The market for ancient coins can feel like the Wild West. For every genuine treasure, there’s a clever fake waiting for an unsuspecting buyer. This makes finding the right roman coins to buy feel intimidating. The most important question isn’t just what to collect, but finding the best place to buy roman coins without getting burned. A beautiful coin with a great story is worthless if it’s not real. This guide is your roadmap. We’ll show you how to identify trustworthy dealers and spot the subtle signs of a forgery, so you can find authentic roman coins for sale and build your collection with confidence.
Key Takeaways
- Authentication is Non-Negotiable: A coin’s story and value hinge on it being real. Prioritize pieces certified by third-party services like NGC or PCGS, and learn the basic physical signs that distinguish a genuine, hand-struck coin from a modern fake.
- A Reputable Dealer is Your Best Asset: The quality of your collection depends entirely on the quality of your source. Choose sellers with a long history of positive reviews, a lifetime guarantee of authenticity, and a clear, fair return policy.
- Build Your Collection with a Clear Plan: You don’t need a massive budget to start. Begin with affordable bronze or common silver coins to learn the market, set a spending limit you’re comfortable with, and always handle your coins by their edges to preserve their condition.
What Makes a Roman Coin Authentic?
When you hold a Roman coin, you’re holding a direct link to emperors, legions, and an ancient world. It’s a tangible piece of history. But with that history comes a critical question: is it real? Authenticity is the bedrock of any collection, determining whether you have a priceless artifact or a simple souvenir. It’s what protects the coin’s story and, just as importantly, its value. While it takes years for experts to master the art of authentication, you don’t need a decade of experience to start making smart, confident purchases.
The most reliable way to confirm a Roman coin is genuine is to have it evaluated by a professional. At PGS Gold & Coin, our experts have spent their careers studying the subtle details that separate authentic coins from forgeries. However, arming yourself with some foundational knowledge is the first step toward building a great collection. Understanding what to look for in documentation, professional grading, and the coin’s physical characteristics empowers you to ask the right questions and vet potential purchases. This knowledge helps you protect your investment and ensures that every piece you add to your collection is a genuine piece of the past.
Why You Need Certificates and Documentation
Think of a Certificate of Authenticity (COA) as a coin’s official passport. Issued by a reputable dealer, this document is a written guarantee that the item you’re buying is genuine. A proper COA should include a detailed description of the coin, a clear photograph, and any known history or provenance. This paperwork is more than just a formality; it’s the dealer’s promise to stand behind their sale. It provides a crucial layer of security for your purchase and is essential for insurance purposes or if you decide to sell the coin in the future. Always ask about the documentation that comes with a coin.
Does Professional Grading Matter? (NGC & PCGS)
For an even higher level of assurance, look for coins certified by a third-party grading service. Companies like Numismatic Guaranty Company (NGC) and Professional Coin Grading Service (PCGS) are the gold standard in the industry. They provide an unbiased, expert opinion on a coin’s authenticity and condition. After a thorough examination, the coin is encapsulated in a sealed, tamper-evident holder—often called a “slab”—with a label detailing its grade and unique certification number. Many of the world’s most significant ancient coins are certified this way, giving collectors ultimate peace of mind and making the coins easier to value and trade.
Key Physical Details to Inspect
Before a coin is ever sent for professional grading, you can learn to spot some key physical clues yourself. Start by examining the coin’s overall characteristics. Authentic Roman coins were struck by hand, so they often have slightly irregular shapes and edges—they won’t look like perfectly round, machine-made modern coins. Look closely at the details: the inscriptions should be crisp, and the portraits of emperors or gods should have noticeable depth and relief. Fakes made from molds often appear flat or “mushy,” and you might even spot tiny bubbles on the surface or a faint seam around the edge where the mold came together.
Factors That Determine a Coin’s Rarity and Value
Once you’ve confirmed a coin is authentic, the next step is understanding what makes it valuable. It’s not always the oldest or shiniest coin that commands the highest price. A coin’s worth is a fascinating mix of its history, scarcity, and unique characteristics. Two coins made from the same metal and from the same era can have vastly different values based on the story they tell and how many others like them exist. Understanding these key drivers will help you appreciate the true significance of a Roman coin, whether you’re building a collection or looking to sell an inherited piece.
Historical Importance
Every Roman coin is a small piece of propaganda, a message from the emperor to his people. Because of this, they act as tiny windows into the past, offering clues about the politics, religion, and major events of the time. Coins that commemorate a specific military victory, the founding of a new city, or the completion of a famous structure like the Colosseum are especially desirable. They connect a collector to a specific moment in history, making them far more compelling than a standard-issue coin. The historical context is a huge part of a coin’s story, and a great story always adds value.
Emperors with Short Reigns
The basic economic principle of supply and demand is a major driver of a Roman coin’s value. Emperors who had long, stable reigns produced millions of coins, many of which survive today. However, some emperors ruled for only a few months before being overthrown or assassinated. These short reigns meant very few coins bearing their portrait were ever minted, making them incredibly scarce. Collectors who want to assemble a complete set of emperors will pay a premium for these hard-to-find pieces. Identifying a coin from a short-reigning emperor can turn a seemingly ordinary piece into a significant find.
Unique Designs and Minting Errors
Beyond history and scarcity, artistry and imperfection play a big role in a coin’s value. Some Roman coins are celebrated for their exceptional artistic quality, featuring detailed portraits or intricate reverse designs that are miniature works of art. On the other end of the spectrum are minting errors. Because each coin was struck by hand, mistakes happened. While minor variations are common, significant errors—like a coin being struck twice (double-struck) or on the wrong size piece of metal—create a truly unique artifact. These one-of-a-kind oddities are highly prized by collectors for their rarity and character.
Where Can You Buy Authentic Roman Coins Online?
Finding authentic Roman coins online can feel like a treasure hunt. The internet gives you access to a global marketplace, but it also requires a careful approach to avoid fakes and overpriced items. The key is to stick with reputable dealers who have a proven track record of authenticity, transparency, and excellent customer service. A trustworthy seller will always stand behind their coins, provide clear documentation, and often offer third-party certification from services like NGC or PCGS. This independent verification is one of the best ways to ensure you’re buying a genuine piece of history.
Whether you’re just starting your collection or searching for a rare, investment-grade piece, knowing where to look is the first step. The best online sources range from curated collections at established dealers to large marketplaces and specialized auction houses. Each platform offers a different buying experience, so it’s helpful to explore a few to see which one fits your collecting style and budget. For example, a large marketplace might be great for browsing a wide variety, while a specialized dealer can offer deep expertise on specific types of coins. Below are some of the most trusted places to find and purchase genuine Roman coins, each vetted for their commitment to quality and authenticity.

A Note on eBay
Navigating a massive marketplace like eBay can feel overwhelming, but it can also be a rewarding place to find Silver Roman Imperial Coins. The sheer volume of listings means you can find a huge selection, and the competitive environment often leads to good deals. However, the key to success on eBay is to buy the seller, not just the coin. Carefully vet every seller’s profile before placing a bid or making a purchase. Look for established sellers with a long history of positive feedback specifically for ancient coins. A reputable dealer on eBay will have a clear return policy and should offer a lifetime guarantee of authenticity. Treat it as a platform to connect with experienced dealers rather than a simple bargain bin.
Other Reputable Marketplaces and Sellers
Beyond the major platforms, the world of ancient numismatics is supported by a network of specialized dealers and auction houses. Each offers a unique focus and buying experience, catering to different types of collectors. Exploring these sellers can help you discover new areas of interest and find high-quality, authentic coins from trusted sources. Here are a few more respected names to know as you continue your search for the perfect addition to your collection.

How to Choose a Reputable Roman Coin Seller
Finding the right Roman coin is only half the battle; finding the right seller is just as important. The ancient coin market is built on trust, and a dealer’s reputation can tell you everything you need to know about the quality and authenticity of their inventory. A great seller doesn’t just complete a transaction—they provide peace of mind, stand behind their products, and offer the expertise you need to build a collection you’re proud of. Before you make a purchase, it’s essential to do a little homework on the dealer. Taking these few extra steps can protect you from fakes, overpaying, and a whole lot of buyer’s remorse. Think of it as the first and most critical investment in your collection.
Start with Customer Reviews and Ratings
A dealer’s track record is one of the clearest indicators of their trustworthiness. Look for sellers with a substantial history of positive feedback on platforms like Google, Yelp, or their own website. Don’t just glance at the star rating; read through the comments to see what people are saying about their experience. Are customers happy with the authenticity of the coins? Do they mention fair pricing and excellent customer service? At PGS Gold & Coin, we’re proud of our thousands of five-star reviews and A+ rating with the Better Business Bureau, because it reflects our commitment to every person who walks through our doors or visits our site. A long history of satisfied customers is a sign you’re in good hands.
Insist on Guarantees and Return Policies
Any reputable dealer will stand firmly behind the authenticity of their coins. A lifetime guarantee of authenticity is the industry standard and should be a non-negotiable part of your purchase. This is your assurance that the seller has done their due diligence and is confident in what they’re selling. Beyond that, check for a clear and fair return policy. A seller who offers a reasonable return window shows they care about your satisfaction and are confident you’ll be happy with your coin. If a dealer is hesitant to offer these assurances, it’s a major red flag. True experts are always willing to back up their claims and their inventory.
Check for Professional Affiliations
Serious coin dealers are active members of the numismatic community. Look for affiliations with respected organizations like the American Numismatic Association (ANA) or the Professional Numismatists Guild (PNG). Membership in these groups means the dealer adheres to a strict code of ethics. Additionally, many top-tier sellers offer coins that have been professionally graded and authenticated by third-party services like the Numismatic Guaranty Corporation (NGC) or the Professional Coin Grading Service (PCGS). While not every coin needs to be graded, a dealer’s access to and use of these services shows a commitment to quality and transparency.
Make Sure Your Payment Method is Secure
When buying online, your financial security is paramount. Ensure the seller’s website uses secure payment processing, indicated by “https://” in the URL and a padlock icon in the address bar. Reputable dealers offer trusted payment options and provide clear information about shipping, insurance, and tracking for your order. Whether you’re making a purchase through our secure online store or in person at one of our locations, the transaction should always feel safe and transparent. A professional seller will make sure your investment is protected from the moment you click “buy” until it’s safely in your hands.
Popular Roman Coins to Add to Your Collection
The Roman Empire’s currency system was incredibly complex, with coins minted from gold, silver, and bronze to serve every level of society. This variety is what makes collecting them so fascinating. Whether you’re drawn to the prestige of gold used for massive imperial payments or the humble bronze pieces that passed through the hands of everyday citizens, there’s a Roman coin that tells a story. Understanding the main types is the first step in building a collection you’ll love. Let’s look at some of the most popular categories you’ll encounter.
Gold Aureus Coins
The gold aureus was the pinnacle of Roman currency, a coin of immense value and prestige. Used for large-scale transactions like military payrolls, imperial bonuses, and international trade, the aureus was a symbol of power and wealth. Because of their high value, they were not everyday coins for the average Roman. For collectors today, the aureus is highly prized for both its intrinsic gold value and its historical weight. Holding one feels like holding a direct link to the empire’s elite. These stunning gold pieces are a cornerstone for many serious collectors, and you can often find graded examples in our online collection of ancient coins.
Silver Denarius Pieces
If the aureus was the coin of emperors, the silver denarius was the coin of the people. As the backbone of the Roman economy for centuries, this was the silver piece used for everything from paying taxes to buying goods in the marketplace. It was the standard daily wage for a skilled laborer or soldier. Because they were so widely circulated, denarii offer an incredible variety of designs, featuring different emperors, gods, and historical events. This makes them a fantastic and accessible starting point for new collectors. Each denarius is a small piece of silver that captures the pulse of daily life in the ancient world.
Silver Antoninianus Coins
The silver antoninianus is a coin with a fascinating, slightly troubled history. Introduced by Emperor Caracalla in 215 AD, it was intended to be worth two denarii, but it was made with less silver—a clever but ultimately flawed attempt to stretch the state’s finances. This coin became a key player during the economic turmoil of the Third-Century Crisis, as its silver content continued to drop over time. For collectors, each antoninianus is a small snapshot of this challenging period. They feature a wide array of designs, from imperial portraits to depictions of Roman gods, making them one of the most popular Roman coins to collect. Because they are more common and affordable than gold coins, they offer a perfect entry point for anyone wanting to own a genuine piece of the empire’s dramatic history.
Bronze Sestertius and As Coins
For a true sense of the Roman street-level economy, look no further than bronze coinage. The sestertius, a large and satisfyingly heavy brass coin, and the smaller bronze as were the workhorses of daily commerce. These were the coins used to buy bread, wine, and other everyday necessities. While they lack the glamour of gold or silver, their historical value is immense. They are generally more affordable and abundant, allowing collectors to acquire pieces from various eras and emperors without a huge budget. Their large size, especially that of the sestertius, often allowed for detailed and artistic portraits, making them beautiful display pieces.
Bronze Follis Coins
If you’re looking for the most budget-friendly way to own a real piece of Roman history, the bronze follis is your perfect entry point. Introduced during the major currency reforms of the late 3rd and 4th centuries, these coins were minted in massive quantities across the empire. Because they are so common, you can often find authentic examples for as little as $10 to $30. Despite their low price, each follis is a genuine artifact that passed through the hands of soldiers, merchants, and citizens during a transformative period that included emperors like Diocletian and Constantine the Great. They offer a tangible connection to the past without requiring a significant investment.
Provincial Tetradrachm Coins
For collectors fascinated by the cultural diversity of the Roman Empire, provincial tetradrachms are a fantastic choice. These large silver coins were minted in the eastern provinces, such as Syria and Egypt, and their designs often blend traditional Roman imperial portraits with distinct local artistic styles. This fusion creates unique and often intricate imagery that tells a story of a vast, multicultural empire. Their value can range widely based on rarity, condition, and the historical importance of the mint location, making them an exciting area to explore. A provincial tetradrachm adds a layer of depth to any collection, showcasing the rich numismatic history beyond Rome itself.
Provincial vs. Imperial: What’s the Difference?
Beyond the metal type, collectors often specialize in either imperial or provincial coins. Imperial coins were minted in Rome (or under direct imperial authority) and circulated throughout the empire. Provincial coins were struck in various provinces, from Britain to Egypt, and were often intended for local use. This is where collecting gets really interesting. You can build a collection around a specific emperor like Augustus or Nero, or focus on a theme, like the coins minted by Mark Antony during the civil wars after Caesar’s death. Deciding on a focus like this can give your collection a compelling narrative and help you become an expert in a specific niche of Roman history.
Famous and Historically Significant Coins
Some Roman coins are more than just currency; they are historical documents that capture pivotal moments in time. These are the pieces that tell dramatic stories of ambition, betrayal, love, and legacy. For passionate collectors and strategic investors, acquiring one of these coins is like owning a headline from the ancient world. They are often the crown jewels of a collection, not just for their rarity or value, but for the powerful narratives they represent. While many of these iconic pieces are exceedingly rare, understanding their stories can inspire your own collecting goals and help you appreciate the rich history behind the coins you encounter.
The EID MAR Denarius of Brutus
If there’s one coin that embodies political rebellion, it’s the EID MAR denarius. Minted by Brutus in 42 BC, this silver coin is a bold and defiant celebration of the assassination of Julius Caesar. The name itself refers to the Ides of March, the day the deed was done. One side features a portrait of Brutus, while the other shows a liberty cap flanked by two daggers—a powerful symbol of freedom from tyranny. This isn’t just a coin; it’s a piece of propaganda that captures one of history’s most dramatic turning points. Because of its direct connection to such a monumental event, the EID MAR denarius is one of the most sought-after and valuable coins in all of numismatics.
Julius Caesar Portrait Denarius
Before Julius Caesar, it was unheard of for a living Roman to have their portrait on a coin; that honor was reserved for gods or long-dead ancestors. Caesar shattered that tradition in 44 BC, minting a denarius that featured his own likeness. This was a radical power move, signaling a shift from Republic to Empire and cementing his status as an absolute ruler. The coin was a clear statement of his authority and influence. For collectors, this piece is significant not just because it depicts one of history’s most famous figures, but because it represents a fundamental change in Roman culture and politics. It’s a tangible artifact of Caesar’s ambition, struck just before his assassination.
Titus Colosseum Sestertius
Imagine holding a coin that commemorates the grand opening of the Colosseum. The Titus Colosseum sestertius, minted around 80 AD, does just that. This large bronze coin features a stunningly detailed architectural rendering of the famous amphitheater, complete with spectators. It was struck to celebrate the inaugural games hosted by Emperor Titus, an extravagant festival that lasted for 100 days. These coins are incredibly rare and serve as a direct link to the grandeur and spectacle of ancient Rome. Owning one is like having a ticket to one of the most famous events in the empire’s history, making it a prized possession for anyone fascinated by Roman architecture and culture.
Mark Antony & Cleopatra Denarius
Few stories are as legendary as the romance and political alliance between Mark Antony and Cleopatra. This famous silver denarius, struck around 32 BC, captures their partnership for eternity. One side features a portrait of Antony, while the other displays the image of the Egyptian queen, Cleopatra. The coin was minted to pay Antony’s legions during his ill-fated war against Octavian (the future Emperor Augustus). It’s a powerful symbol of their combined ambition and the deep connection that ultimately led to their downfall. For collectors, this coin is a tangible piece of one of history’s greatest love stories, blending romance, power, and tragedy into a single, remarkable artifact.
How Much Should You Expect to Pay?
One of the best things about collecting Roman coins is that it’s a hobby accessible to nearly everyone. You might be surprised to learn that you can own a genuine piece of history for less than the cost of a night out. Of course, prices can also reach astronomical heights for the rarest and best-preserved specimens. The value of a Roman coin depends on several key factors: its rarity, the metal it’s made from (gold, silver, or bronze), its condition or grade, and its historical significance. Understanding these price tiers will help you set a realistic budget and find the perfect coins for your collection.
Entry-Level Finds (Under $25)
You don’t need a fortune to become a collector. In fact, you can own a genuine piece of Roman history for less than the price of a movie ticket. The most accessible starting point is the world of late Roman bronze coins. Minted in vast quantities during the 4th and 5th centuries AD, these coins are widely available and incredibly affordable. It’s common to find identifiable bronze pieces from this period for under $10, and sometimes for just a few dollars. At this price, you’re not buying a museum-grade artifact, but you are acquiring a tangible connection to the past—a coin that passed through the hands of Roman citizens centuries ago. It’s the perfect way to learn how to identify emperors, handle ancient coins, and begin your journey into numismatics without a significant investment.
Starting Your Collection ($25-$100)
If you’re just starting, you don’t need a large budget to acquire some fascinating pieces. This is the perfect range to get your feet wet. You can find a wide variety of common bronze coins, often from the later Roman Empire, for as little as $15 to $50. These coins allow you to hold real history in your hands and learn to identify emperors and different design elements without a major financial commitment. For under $100, you can easily build a small, diverse group of coins that tells a story and helps you discover what aspects of Roman history you enjoy most.
For the Growing Collector ($100-$500)
Once you have a few coins and a better sense of what you like, the $100 to $500 range opens up a whole new world. Here, you’ll find higher-quality bronze coins with clearer details and more attractive patinas. This is also the price point where you can start acquiring the famous Roman silver denarius, especially those from more common emperors or in average condition. This tier is ideal for the dedicated hobbyist looking to build a more substantial and historically significant collection, focusing on specific rulers or themes without breaking the bank.
Serious Investment Pieces ($500-$5,000)
This is where collecting begins to overlap with serious investing. Coins in this price range are typically in excellent condition, professionally graded, or are significantly rarer than more common types. You can find beautiful silver denarii of sought-after emperors, large and impressive bronze sestertii, and even some gold coins from the later empire. These pieces are not just historical artifacts; they are tangible assets that tend to hold their value well over time. Collectors and investors who shop for coins in this tier are often looking for a combination of historical importance and long-term financial worth.
The Rarest of the Rare ($5,000+)
At the highest end of the market, you’ll find the museum-quality treasures that are the crown jewels of the numismatic world. These coins can cost tens or even hundreds of thousands of dollars. They are exceptionally rare, often because they were minted by a short-reigning usurper, commemorate a major historical event, or have survived in near-perfect condition for two millennia. Acquiring a coin at this level is a major investment that requires deep expertise and trust. Working with a reputable dealer for an expert evaluation is absolutely essential to ensure you are purchasing an authentic and fairly priced masterpiece.
The Niche of “Uncleaned” Roman Coins
What to Know Before You Buy a Bulk Lot
You might come across sellers offering “uncleaned” Roman coins, often sold in bulk lots covered in centuries of dirt. The appeal is obvious: it’s a hands-on treasure hunt where you get to be the archaeologist, carefully cleaning each piece to reveal the history beneath. It’s an affordable way to get into the hobby, and the process of discovery can be genuinely exciting. However, it’s crucial to approach this niche with realistic expectations. These lots are almost never truly “unsearched.” They have likely been picked over by experts who have already removed any valuable or rare coins, leaving behind the common and often heavily worn pieces for new collectors.
Think of buying uncleaned coins as an educational project rather than a financial investment. A significant portion of any given lot will likely be “slugs”—coins that are too corroded or worn to be identified—and there’s always a risk of fakes being mixed in. If your goal is to build a collection of identifiable, historically significant pieces, you are far better off purchasing individual coins from a trusted dealer’s curated inventory. This approach ensures you know exactly what you’re getting and can be confident that you’re investing in a genuine artifact, not just a fun weekend activity that may or may not yield a recognizable coin.
How to Spot a Fake Roman Coin
As you build your collection, learning to identify forgeries is one of the most important skills you can develop. While modern fakes can be incredibly deceptive, many reproductions have tell-tale signs that give them away. Knowing what to look for can protect you from a bad purchase and deepen your appreciation for the real deal. The best defense is a good offense, which means training your eye to spot the subtle inconsistencies that separate a genuine artifact from a clever copy. It’s a skill that grows with experience, and every coin you examine, real or fake, helps you learn.
Of course, some fakes are so convincing that they can fool even seasoned collectors. When you’re in doubt, the safest route is always to seek a professional opinion. Bringing your coin to a trusted dealer for an expert evaluation is the surest way to confirm its authenticity and get a clear understanding of its value. Think of it as an investment in your peace of mind and the integrity of your collection. Below, we’ll cover some of the key areas to inspect when you’re trying to determine if a Roman coin is authentic. These checks won’t make you an expert overnight, but they will give you a solid foundation for making smarter buying decisions.
Look Closely at the Craftsmanship
Authentic Roman coins were struck by hand, not mass-produced by modern machines. This minting process gives them a distinct character. When you examine a genuine coin, look for clear, sharp details. You should be able to make out inscriptions, facial features on emperors, and the intricate designs of gods or goddesses. The relief, or the depth of the design, should be noticeable. If a coin’s details look soft, mushy, or flat, it might be a cast fake. Casting often fails to capture the crisp, high-relief details created by a hammer strike.
Does the Weight and Size Seem Right?
Ancient mints had standards, but the hand-production process meant there were slight variations. However, fakes are often significantly off the mark. One of the quickest checks you can perform is to weigh the coin and measure its diameter. You can find the standard specifications for most Roman coins in online databases or reference books. If your coin’s weight and size are noticeably different from recorded authentic examples, it’s a major red flag. Fakes are frequently made from different, less-valuable metals, which causes these discrepancies.
Is the Patina Natural or Faked?
For bronze and copper coins, one of the best indicators of age is the patina—a thin layer of oxidation that forms on the surface over centuries. A natural patina is stable, often colorful (greens, browns, or reds), and integrated into the coin’s surface. It should look and feel like a part of the coin itself. Be wary of coins that look too new or have a patina that appears powdery, chalky, or can be easily flaked off with a fingernail. These are often signs of an artificially applied chemical treatment designed to mimic the appearance of age.
Watch Out for Modern Tool Marks
The way a coin was made leaves behind clues. Look closely at the edge of the coin. Many cast fakes are made using a mold, which can leave a thin seam or filing marks where the two halves of the mold met. Authentic Roman coins were struck on hand-prepared metal discs (planchets) and won’t have this feature. Also, check for small bubbles or pits on the surface, which are common in cast forgeries. Finally, if a coin looks perfectly round, be suspicious. Hand-struck coins are almost always slightly irregular in shape.
Your First Steps as a Roman Coin Collector
Diving into the world of Roman coin collecting is an incredible way to hold history in your hands. But before you start buying, it’s smart to build a solid foundation of knowledge. Focusing on a few key areas from the beginning will help you make confident choices, protect your investments, and get the most enjoyment out of your new hobby. Think of it as your collector’s toolkit—a set of skills and resources that will serve you well as you build a collection you can be proud of. These fundamentals are what separate a casual buyer from a true collector.
First, Learn the Basics of Roman Coinage
Before you can appreciate the value of a Roman coin, it helps to understand its original purpose. These weren’t just pieces of money; they were powerful tools for mass communication. In an empire without television or the internet, coins were the most effective way for an emperor to spread his portrait, titles, and political messages to every corner of the known world. Each coin tells a story, celebrating a military victory, a new building project, or the emperor’s divine status. Understanding this context transforms you from someone who just owns old coins into someone who can read the history behind them.
Set a Clear Budget for Your Collection
You don’t need an emperor’s treasury to start collecting Roman coins. In fact, you can find fascinating, authentic pieces for less than $100. The key is to set a clear budget before you start shopping. Decide what you’re comfortable spending on a single coin and for your collection overall. This will help you focus your search and avoid overspending. While rare coins in pristine condition can cost thousands, many historically significant ancient coins are surprisingly affordable. Starting with a modest budget allows you to learn the ropes and discover what types of coins truly capture your interest.
How to Properly Store and Handle Your Coins
These coins have survived for nearly 2,000 years, and your first job as a collector is to preserve them for the future. Proper handling and storage are non-negotiable. Always hold a coin by its edges to avoid getting skin oils on its surface, which can cause corrosion over time. Never, ever try to clean your coins with soap, polish, or other abrasives, as this can destroy their historical patina and drastically reduce their value. Instead, store them in archival-safe holders, such as non-PVC plastic flips, which protect them from environmental damage without reacting with the metal.
Safe Storage Solutions
When it comes to storage, your goal is to create a stable, protective environment. The best options are made from materials that won’t break down and harm your coins over time. Look for archival-quality, non-PVC plastic flips—often called “safety flips”—or acid-free paper envelopes. For a more organized display, consider multi-slot coin albums with inert plastic pages. These materials create a barrier against moisture and contaminants without leaching harmful chemicals, which is a common problem with cheap, flexible plastics. Store your collection in a cool, dry place with stable temperatures, like a drawer or a safe, rather than a damp basement or a hot attic. This simple step is one of the best ways to preserve your coins for generations.
What to Avoid When Cleaning and Storing
The single biggest mistake a new collector can make is trying to clean a Roman coin. It might seem like a good idea to polish a tarnished silver denarius or scrub dirt off a bronze sestertius, but doing so can permanently damage the coin and erase most of its value. That layer of toning or dirt is called a patina, and it’s a natural part of the coin’s aging process. Experts see it as proof of authenticity and history. Removing it is like stripping the original finish off an antique piece of furniture. Stay away from metal polishes, jewelry cleaners, toothbrushes, and any kind of abrasive substance. An expert evaluation can determine if professional conservation is needed, but you should never attempt it yourself.
Find Your Community and Helpful Resources
Collecting doesn’t have to be a solo activity. Connecting with other enthusiasts is one of the best ways to deepen your knowledge and share your passion. Online forums and local clubs are great places to ask questions, see what others are collecting, and get advice from experienced numismatists. You can also find incredible educational resources through organizations like the American Numismatic Association, which offers articles, courses, and events. Building a network of fellow collectors and trusted experts will make your journey more rewarding and help you grow as a collector.
Online Identification Tools
Part of the fun of collecting is the detective work, and there are some excellent online resources to help you identify your coins. For coins from the later empire, around 300–500 AD, Tesorillo is a fantastic visual guide. If your coin has clear lettering, the Online Coins of the Roman Empire (OCRE) database allows you to search by inscriptions. For more advanced research when you already have a few details, WildWinds is an extensive database with thousands of examples. Using these tools is a great way to train your eye and learn more about your collection, but remember they don’t replace a professional opinion for confirming authenticity and value on a significant piece.
Online Collector Forums
You’re not alone in your passion for Roman history. Online forums are where you can connect with a global community of collectors who are just as excited about these artifacts as you are. Websites like CoinTalk have dedicated sections for ancient coins where you can post pictures of your latest find, ask for help identifying a tricky piece, or just read through conversations to absorb knowledge from seasoned numismatists. These communities are invaluable for getting advice, learning from others’ experiences, and sharing the thrill of the hunt. It’s a perfect way to deepen your understanding and make your collecting journey even more rewarding.
Should You Visit a Local Coin Dealer?
While online marketplaces offer incredible convenience, there’s something special about stepping into a physical coin shop, especially when you’re dealing with ancient artifacts like Roman coins. The experience provides a level of confidence and education that’s hard to replicate through a screen. For new and seasoned collectors alike, visiting a trusted local dealer can be one of the most rewarding parts of building a collection. It transforms a simple transaction into a personal connection with both the coins and the experts who handle them.
At PGS Gold & Coin, we have five locations in the Chicagoland area where you can see our collection firsthand and speak with our specialists. An in-person visit allows you to ask questions, compare different pieces side-by-side, and make decisions with all the information right in front of you. It’s an opportunity to learn directly from professionals and ensure every piece you acquire is a perfect fit for your collection.
The Advantage of Seeing Coins in Person
Nothing compares to holding a piece of history in your hand. When you buy Roman coins from a physical dealer, you can examine every detail up close. You can feel the coin’s weight, check its size, and inspect the strike and patina with your own eyes. This hands-on evaluation is critical for judging a coin’s condition and authenticity. It helps you develop a feel for what a genuine ancient coin looks and feels like, which is an invaluable skill for any collector. This direct interaction gives you a much stronger sense of confidence in your purchase than simply looking at photos online ever could.
Why You Should Build a Relationship with an Expert
Building a relationship with a knowledgeable coin dealer is one of the best investments you can make in your hobby. A trusted expert does more than just sell you coins; they become a guide on your collecting journey. They can offer valuable insights, help you identify your interests, and point you toward pieces that fit your budget and goals. A local dealer gets to know you and your collection, often setting aside specific coins they think you’ll love. This personalized guidance helps you avoid common mistakes, learn to spot fakes, and build a collection that truly reflects your passion.
Get Your Coins Authenticated on the Spot
One of the biggest advantages of visiting a brick-and-mortar shop is the access to on-the-spot expertise. Instead of buying a coin online and waiting anxiously for it to be authenticated, you can get a professional opinion right away. Our experts can help verify a coin’s authenticity during your visit, saving you time, money, and the hassle of shipping items to third-party graders. This immediate feedback is especially helpful when you’re considering a significant purchase. It provides peace of mind and confirms you’re adding a genuine, high-quality piece to your collection, backed by the dealer’s professional assessment.
Common Mistakes to Avoid When You Buy Roman Coins
Collecting Roman coins is like holding a piece of history in your hands. Each coin tells a story of an emperor, a battle, or a cultural shift. But as with any valuable collectible, the market has its share of risks. For every genuine treasure, there’s a potential pitfall that can turn an exciting purchase into a costly mistake. Understanding these common traps is the first step toward building a collection you can be proud of.
The most significant challenges for new and even experienced collectors are telling real from fake, knowing a fair price, finding a trustworthy seller, and understanding the importance of proper documentation. The allure of a rare find can sometimes cloud judgment, leading buyers to overlook red flags. Forgeries have become increasingly sophisticated, and the vast range of coin types means that pricing can be complex. Without a trusted expert to guide you, it’s easy to feel overwhelmed. By learning to spot these issues, you can protect your investment and ensure the coins you acquire are authentic, fairly priced, and a genuine asset to your collection.
Avoiding Fakes and Modern Reproductions
The market for Roman coins is unfortunately filled with fakes, forgeries, and modern reproductions passed off as originals. Some of these are crude tourist souvenirs, but others are deceptive fakes created to fool serious collectors. While learning the characteristics of genuine coins—like proper weight, style, and signs of age—is a valuable skill, visual inspection alone is often not enough. The most reliable way to be certain a Roman coin is real is to have it examined by a professional. An expert numismatist can spot subtle inconsistencies in manufacturing methods, wear patterns, and metal composition that an untrained eye would miss. Don’t risk your money on a guess; professional authentication is the best protection for your investment.
Don’t Overpay for Common Coins
A common misconception is that all ancient Roman coins are incredibly rare and expensive. While some can be worth thousands of dollars, many are quite common and affordable. The price of a Roman coin depends on its rarity, historical significance, metal type, and, most importantly, its condition or grade. For example, coins of late-empire rulers like Constantine are often abundant and can be purchased for less than $100. New collectors sometimes overpay for these common coins because they aren’t familiar with the market. Before making a purchase, research recent sale prices for similar coins and consult with a reputable dealer who can provide an honest assessment of a coin’s value.
Steer Clear of Unvetted Sellers
Where you buy your coins is just as important as what you buy. The internet has made it easy to find coins for sale, but it has also opened the door for untrustworthy sellers. Be cautious when buying from online auction sites or forums where sellers are anonymous and accountability is low. You should always research sellers before you buy anything. A reputable dealer will have a long-standing history, transparent business practices, and positive customer reviews. Look for sellers who have a physical storefront, as it adds a layer of legitimacy and service. Always prioritize dealers who guarantee the authenticity of their items and offer clear return policies.
Never Buy a Coin Without Paperwork
A Roman coin sold without any documentation or certification should be approached with caution. Professional authentication does more than just confirm a coin is real; it also provides an impartial grade of its condition, which is a major factor in its market value. Third-party grading services like Numismatic Guaranty Company (NGC) and Professional Coin Grading Service (PCGS) encase certified coins in secure, tamper-proof slabs with detailed labels. This certification provides peace of mind and makes the coin easier to sell in the future. While you can certainly buy “raw” (ungraded) coins, doing so carries more risk. For significant purchases, always prefer coins that have been professionally graded and certified.

Frequently Asked Questions
Is it better to buy a professionally graded coin or a “raw” one? This really depends on your goals. If you’re new to collecting or making a significant purchase, buying a coin that has been graded and encapsulated by a service like NGC or PCGS is a great idea. It gives you a guarantee of authenticity and a clear assessment of its condition, which takes the guesswork out of the equation. On the other hand, many collectors enjoy “raw” coins because they can handle them directly and they are often more affordable. The right choice comes down to your comfort level with assessing coins yourself and the level of security you want for your purchase.
I inherited a Roman coin. What’s the first thing I should do? The most important first step is to resist the urge to clean it. That layer of grime or color is actually a natural patina that has formed over centuries, and removing it can drastically reduce the coin’s value. Handle it carefully by its edges and store it in a soft, dry place. The next step is to have it identified and evaluated by a professional who can tell you exactly what you have, its history, and its current market value.
Are Roman coins a good financial investment? They certainly can be. Because they are tangible historical assets, their value isn’t directly tied to the fluctuations of the stock market. High-quality, rare coins have a strong track record of holding and increasing their value over time. However, it’s best to approach it as a collector first and an investor second. The market is driven by rarity, condition, and historical demand. The wisest strategy is to buy the best quality coins you can afford and focus on pieces you genuinely find fascinating. Any financial gain should be seen as a bonus to owning a piece of history.
Is it ever okay to clean an ancient coin? In a word, no. Cleaning an ancient coin is one of the most common and damaging mistakes a new collector can make. That surface patina is a key part of the coin’s history and authenticity, and collectors value it highly. Using polish, abrasives, or even soap and water can strip this layer away, leaving behind unnatural scratches and an altered surface that can destroy its historical and financial value. Leave any restoration work to trained museum conservators.
What’s a good “starter” coin for a new collector? A silver denarius is a fantastic place to start. These coins were the workhorses of the Roman economy for centuries, so they are widely available and relatively affordable. You can find a nice example from a famous emperor like Trajan or Hadrian for a reasonable price. Another great option is a large bronze coin from the later empire, such as one depicting Constantine the Great. Both options give you a substantial, authentic piece of history to hold without a major financial commitment.
