How to Spot Rare Errors and Varieties at the Richmond Coin Club Show: A Hunter’s Field Guide to Die Cracks, Double Dies, and Mint Mark Variations

Most people walk right past the tiny details that can turn a common coin into a rarity worth thousands. That’s the hardest truth in this hobby, and it’s one I’ve learned firsthand after over two decades of hunting error coins and die varieties — at shows, in dealer bargain bins, and through grading services across the country. If you’re heading to the Richmond Coin Club Show coming up April 30 – May 2, 2026 at the AccA Shriners Center, 1712 Bellevue Ave., Richmond, VA 23227, you’re walking into one of the best opportunities in the entire Mid-Atlantic region to find exactly those kinds of overlooked treasures.

With 57 dealer tables, free admission, free parking, free appraisals, and — most importantly — ANACS on-site accepting submissions, this is the kind of show where a serious error coin hunter can make their entire year. I’ve been to this venue before, and I can tell you from personal experience: the dealers here bring quality material, and the bargain bins are where the real money hides. Let me walk you through exactly what to look for, how to identify it, and why this particular show is such a prime hunting ground for varieties and errors.

Why the Richmond Show Is a Hotspot for Error Coin Hunters

Coin shows with on-site grading services create a unique dynamic. Dealers bring their best material because they know collectors are submitting on the spot. Collectors, in turn, are more willing to buy raw coins with potential errors because they can get them authenticated and graded within days. The result? A marketplace where knowledgeable buyers find undervalued coins that the average attendee walks right past.

The Richmond Coin Club has been running this show for years, and the venue — right off I-95 — makes it accessible for collectors traveling from D.C., North Carolina, and beyond. I’ve spoken with Bill Scott (contact: 804-350-1140 or woscott1@gmail.com), and the club consistently delivers a well-organized event. With U.S., foreign, and ancient coins and currency represented across 57 tables, the diversity of material means you’re not just hunting modern mint errors. You’re also looking at historical die varieties, repunched mint marks, and ancient coin anomalies that most collectors never think to examine.

Here’s what I love most about this show: the bargain bins. One collector at last year’s event reported finding coins marked 20% off in the bargain bins, including pieces destined for ANACS submission. That’s the kind of deal that separates the prepared hunter from the casual browser — and it’s exactly why I keep coming back.

Die Cracks: The Most Common (and Most Overlooked) Error

Let’s start with the error you’re most likely to encounter at any coin show: die cracks. These occur when a hardened steel die develops a fracture from the immense pressure of striking coins. Metal flows into the crack during the strike, producing a raised line on the surface of the coin. They’re everywhere — once you know what to look for, you’ll start seeing them on nearly every table.

How to Identify Die Cracks

• Raised lines, not incised: A die crack appears as a raised line on the coin’s surface, not a scratch or gouge. Run your fingernail across it and you’ll feel it lift up from the field. That tactile test alone will save you from confusing post-mint damage with a genuine error.
• Irregular paths: Unlike intentional design elements, die cracks follow jagged, branching paths. They often radiate from high-stress areas like the rim, lettering borders, or around the date. If the line looks too “designed” to be a crack, it probably is.
• Consistent across coins from the same die: This is the real power move. If you find one coin with a die crack, check other coins of the same date and mint mark on the same table. The crack will appear in the identical location on every coin struck by that die. Finding two examples at the same show confirms the variety and boosts the collectibility of both pieces.

When Die Cracks Become Valuable

Not all die cracks are created equal — far from it. A minor crack running from the rim into the field might add only a small premium. But when you find a die crack that connects two major design elements (say, from a star to the rim), or one accompanied by a die break where a chunk of the die actually fell out creating a raised blob of metal, or one appearing on a key date or semi-key date coin — that’s when you’re looking at serious numismatic value.

I once found a 1955 Lincoln cent with a dramatic die crack running from the wheat stalks through the rim at a show not unlike this one. The dealer had it in a 25-cent bin. It graded MS-64 Red with the die crack noted on the ANACS holder and sold for over $150. That single find paid for my entire weekend — and then some.

Double Dies: The Crown Jewel of Error Hunting

If die cracks are the common cold of the error world, double dies are the crown jewel. These occur when a die receives multiple impressions from the hub that don’t perfectly align, resulting in visible doubling of design elements. The eye appeal of a strong doubled die is immediate and dramatic.

The most famous example is the 1955 Doubled Die Lincoln cent, which can sell for $1,000 to $25,000+ depending on condition. But double dies exist on virtually every denomination and series, and many of them are still being discovered. The provenance of a newly identified double die — especially one found in the wild at a show — adds a thrill that no amount of online shopping can replicate.

What to Look For

• Doubling of lettering: Check the inscriptions first — LIBERTY, IN GOD WE TRUST, the date, and the mint mark. Look for a distinct secondary image shifted in a consistent direction. Under magnification, the separation between the two images should be visible and crisp.
• Doubling of design elements: On Lincoln cents, examine the bust, wheat ears, and memorial columns. On Jefferson nickels, look at the building columns and the letters of MONTICELLO. The more elements that show doubling, the stronger — and more valuable — the variety.
• Rotation direction: Try to classify the doubling. The famous 1955 cent shows Rotated Hub Doubling (Class I), where the secondary image is rotated around a central point. Other classes include offset, distorted, and modified hub doubling. Knowing the class helps you communicate with other collectors and grading services.

How to Distinguish Real Double Dies from Machine Doubling

This is critical, and it’s where most beginners get burned. Machine doubling damage (MDD) is NOT a true double die. It occurs when a coin shifts slightly during striking, creating a flattened, shelf-like appearance around design elements. Here’s how to tell the difference — and I check this every single time:

• True double die: Shows a distinct, rounded secondary image with clear separation. The doubling appears inside the primary design element and has real dimensional depth.
• Machine doubling damage: Produces a flat, shelf-like “doubling” that extends outward from the design element. It looks like the metal was pushed to one side rather than a second image being applied. Under high magnification, MDD looks smeared. A real double die looks duplicated.

I always carry a 10x loupe to shows, and I’d strongly recommend bringing a 20x or higher magnification jeweler’s loupe for close inspection. When I’m examining a potential double die, I focus on the edges of the letters under magnification. True doubling shows clean separation between the two images. MDD shows a smeared, flattened appearance that falls apart the closer you look. This single skill — telling the difference — will save you more money than any reference book ever could.

Mint Mark Variations: Small Letters, Big Money

Mint mark variations are some of the most rewarding finds for variety hunters, especially on silver dollars and early 20th-century coinage. The mint mark was hand-punched into each die until the mid-20th century, meaning every punch could be slightly different — different position, different angle, different strength. That human element is what makes this area of the hobby so endlessly fascinating to me.

Repunched Mint Marks (RPMs)

An RPM occurs when a mint mark is punched into a die more than once, with the punches slightly offset. The result is a visible “shadow” or secondary mint mark under or next to the primary one. Under good lighting and magnification, these shadows can be dramatic — and they add significant numismatic value to the host coin.

At the Richmond show, I’d specifically recommend examining:

• Morgan Silver Dollars (1878–1921): RPMs on Morgan dollars are extensively cataloged, and many still command significant premiums. Check Carson City (CC), San Francisco (S), and New Orleans (O) mint marks especially. The luster and strike quality on Morgans also helps RPMs stand out more clearly than on worn coinage.
• Peace Dollars (1921–1935): Several notable RPMs exist in this series. One collector at this year’s show traded for a Peace dollar — exactly the kind of coin where an RPM could be hiding in plain sight, adding collectibility that the previous owner never recognized.
• Walking Liberty Half Dollars: RPMs on this series are highly collectible and often underpriced at shows. The delicate design and high relief make mint mark examination a bit trickier, but the payoff is worth the effort.

Specific RPM Characteristics to Hunt

• Direction of repunching: Is the secondary mint mark north, south, east, or west of the primary? Each direction represents a different die variety, and some directions are far rarer than others.
• Degree of overlap: Strong repunches where both mint marks are clearly visible are more desirable than weak ones. A bold secondary punch practically jumps off the coin under magnification.
• Mint mark size and shape: Early mint marks were punched entirely by hand, so a “D” might look slightly different from one die to the next. Learn what a “normal” mint mark looks like for each date so you can spot anomalies immediately.

A Note on GSA Carson City Dollars

One collector at the Richmond show mentioned trading for a GSA 1880-CC Morgan dollar. Carson City dollars are an absolute treasure trove for variety hunters. The VAM (Van Allen-Mallis) catalog lists hundreds of die varieties for CC Morgans, including different mint mark positions and sizes (Large CC vs. Small CC, positioned high, low, left, or right), die scratches and polish lines unique to specific dies, and doubled dies on obverse and reverse elements.

If you find a CC Morgan in GSA packaging at the Richmond show, examine it carefully. The GSA holder and its original government provenance don’t mean it’s a common variety — some of the rarest and most valuable VAMs have been found in GSA holders, where the original packaging actually helped preserve the coin’s mint condition luster and eye appeal. That combination of historical significance and die variety is what makes these coins so special.

Other Specific Errors to Hunt at the Show

Beyond die cracks, double dies, and mint mark varieties, here are the other error types I’d be actively searching for across 57 dealer tables:

Off-Center Strikes

• Look for coins where the design is visibly shifted from center. A 5–10% off-center coin is interesting; 30%+ is genuinely valuable. The visual impact is immediate — you can spot these even without a loupe.
• Check that the date is still visible. Off-center coins with full dates command significantly higher premiums than those where the date is partially or fully missing.
• Lincoln cents, Washington quarters, and Kennedy half dollars are the most common finds in this category, but don’t ignore other denominations.

Broadstrikes

• These occur when the collar die fails to contain the planchet during striking, causing the coin to spread outward under pressure.
• The result is a coin that’s larger than normal diameter with a smooth, unreeded edge. They have a distinctive look that’s easy to spot once you’ve seen one.
• Broadstruck silver coins are particularly desirable because the metal spread means the design is thinner, more detailed, and often exhibits superior strike quality in the central elements.

Clipped Planchets

• A curved clip occurs when the strip of metal from which planchets are punched overlaps a previous punching, creating a crescent-shaped missing section.
• Curved clips on silver and gold coins are especially valuable due to the precious metal content and the dramatic visual appeal of the error.
• Look for the “Blakesley Effect” — opposite the clip, the rim will be distorted and thickened. Confirming this effect is what separates a genuine clipped planchet from post-mint damage.

Wrong Planchet Errors

• A dime struck on a cent planchet, a quarter struck on a nickel planchet — these are dramatic errors that command huge premiums and generate immediate excitement at any show.
• Check the weight and diameter of any coin that looks suspicious. A coin struck on the wrong planchet will be the wrong size, weight, and/or color. A quick check with a digital scale can confirm what your eyes are telling you.
• These are rare, but dealers sometimes don’t recognize them, especially when the error coin has been in circulation and the wear has softened the visual cues. That’s where your knowledge — and your scale — pay off.

Die Cuds and Major Die Breaks

• A die cud is a raised, blob-like area on a coin where a piece of the die broke away entirely. They can range from tiny bumps to massive raised areas that dominate the coin’s surface.
• Cuds near the rim are relatively common; cuds over major design elements like a date or portrait are rare and valuable. The location of the cud is everything.
• Look for coins with unusual raised areas that don’t correspond to any intentional design feature. If you see a lump of metal where there shouldn’t be one, examine it closely — you might be looking at a major die break with significant collectibility.

Your Field Kit: What to Bring to the Richmond Show

After years of hunting errors at coin shows, here’s the kit I never leave home without. Every item earns its place:

1. 10x Triplet Loupe: For general inspection of all coins. I prefer a Hastings triplet for clarity and color correction — it makes a real difference when you’re trying to evaluate luster and patina under show lighting.
2. 20x or 30x Magnifier: For close examination of mint marks and potential doubling. This is non-negotiable for RPM and double die hunting.
3. Good Lighting: A small LED flashlight or headlamp. Many show venues have mediocre overhead lighting, and a focused, angled light source reveals die cracks and doubling that fluorescents completely hide. I can’t stress this enough — better lighting will find you more errors than any other single tool.
4. Reference Materials: The CONECA Error Coin Encyclopedia, Die Variety News, and VAM reference books for silver dollars. Or load these onto your phone — just make sure you have them accessible offline in case the Wi-Fi is spotty.
5. A Scale: A small digital scale that measures to 0.01 grams. Essential for identifying wrong planchet errors. Mine fits in my pocket and has paid for itself dozens of times over.
6. Submission Forms: If ANACS is on-site, bring pre-filled submission forms to save time. Know your turnaround options and fees before you arrive so you can make quick decisions at the table.
7. Cash and Trades: Dealers at shows often prefer cash, and having trade material gives you real negotiating power. One collector I know traded for an 1860-era piece and a GSA 1880-CC dollar at this very show — having desirable trade coins opened doors that cash alone couldn’t.

Bargain Bin Strategy: Where the Real Errors Hide

I’ll let you in on a secret that experienced error hunters already know: the bargain bin is your best friend. Dealers who specialize in high-end material often have bargain bins filled with circulated coins that they haven’t individually examined for errors. They’re priced for quick turnover, not for their potential variety or error value. That’s where the gap between price and numismatic value is widest.

At the Richmond show, collectors have reported finding coins at 20% off in the bargain bins — including material destined for ANACS submission. That’s the kind of deal that pays for your entire show trip before you’ve even left the building.

Here’s my bargain bin strategy, refined over many years:

• Focus on silver first: Morgan and Peace dollars, Walking Liberty halves, and Mercury dimes in bargain bins are where RPMs, die cracks, and doubled dies are most likely to be found. Silver coins tend to hold their detail better in circulated grades, making errors easier to spot.
• Examine every coin: I know it’s tedious, but I go through bargain bins one coin at a time, checking mint marks, dates, and lettering under my loupe. The coins that reward this patience are the ones nobody else bothered to look at carefully.
• Don’t shy away from “ugly” coins: Coins with heavy toning, surface marks, or moderate wear often get overlooked by other buyers chasing mint condition pieces. But an error on a circulated coin is still an error. The price difference between an AU and an MS-63 example can be thousands of dollars, while the error premium remains significant even in lower grades. Eye appeal matters less for errors than you might think.
• Check the foreign and ancient tables: Error coins aren’t just an American phenomenon. Ancient coins with brockages, double strikes, and off-center strikes can be found at reasonable prices if you know what to look for. These tables are often less crowded, which means you get more time with the material.

ANACS On-Site: Why This Changes Everything

The presence of ANACS at the Richmond show is a genuine game-changer for error hunters. Here’s why this matters so much:

• Immediate authentication: You can submit a coin on Thursday and potentially have it graded and slabbed by Saturday. That means you can buy a raw coin, identify the error, submit it, and potentially sell or trade it at the same show with an ANACS-certified label. I’ve done exactly this, and the speed of the process is transformative.
• Expert eyes: ANACS graders are knowledgeable about errors and varieties. If you’re unsure whether a coin is a true double die or machine doubling damage, you can ask for their opinion before submitting. That professional assessment — even informal — can save you a submission fee or confirm a find worth pursuing.
• Variety attribution: ANACS will attribute major die varieties (like recognized VAMs on Morgan dollars and recognized doubled dies on Lincoln cents) on the holder label. This attribution adds significant value and marketability. A coin with a named variety on the slab sells faster and for more than the same coin in a raw flip.
• Market confidence: Dealers know that a certified error in an ANACS holder carries more weight than a raw coin in someone’s flip. That confidence translates directly into better offers when you’re buying or trading. The provenance and authentication provided by on-site grading removes uncertainty from the transaction.

My advice: budget your show money with ANACS submission fees in mind from the start. If you find a coin that looks like a strong variety or error, factor the grading cost (typically $20–$50 per coin depending on service level) into your purchase decision. A $5 bargain bin coin that turns into a $500 ANACS-certified error is the best return on investment in all of numismatics — and it happens more often than you’d think when you know what to look for.

What Collectors Found at Recent Richmond Shows: Real-World Examples

I always believe in practicing what I preach, so let me share what collectors have actually found at the Richmond show in recent years. These aren’t hypothetical scenarios — they’re real finds from real people at this real show:

• An 1806-dated coin was traded and submitted to ANACS. Early American coinage from this era frequently exhibits die cracks, repunched dates, and other striking anomalies that are highly collectible and historically significant.
• A GSA 1880-CC Morgan dollar was acquired through trade. Carson City Morgans are one of the most actively collected series for die varieties, with over 300 VAMs cataloged for the 1880-CC alone. Finding one at a show with an unrecognized variety is entirely possible.
• A Peace Dollar was picked up at the show. The Peace dollar series (1921–1935) has numerous known doubled dies and RPMs that are still being discovered and cataloged by active researchers.
• Multiple bargain bin finds at 20% off — proof that patient, knowledgeable hunters are being rewarded at this show year after year.

These are the kinds of finds that remind me why I keep coming back to shows like this. The coins are out there, waiting for someone with the knowledge and patience to recognize them. The Richmond Coin Club Show consistently delivers for error hunters who come prepared.

Building Your Error Coin Knowledge Before the Show

If you’re serious about hunting errors at the Richmond show — or any show — invest in your education before you go. A few hours of study with the right resources will dramatically improve your hit rate at the tables. Here are the resources I recommend, in order of importance:

• CONECA (Combined Organizations of Numismatic Error Collectors of America): The premier organization for error coin collectors. Their website and publications are essential references for anyone serious about the error side of the hobby.
• Wexler Die Variety Registry: John Wexler’s site catalogs doubled dies and die varieties across all U.S. denominations. It’s free to use and incredibly detailed — I check it regularly, even now.
• VAMWorld: For Morgan and Peace dollar die varieties, this is the go-to resource. Cross-reference any silver dollar you find with the VAM listings before buying. Knowing what you’re looking for before you look is half the battle.
• “The Error Coin Encyclopedia” by Arnold Margolis: The bible of error coin identification. If you only buy one book on this topic, make it this one. It covers the full spectrum of mint errors with clear photographs and practical identification guidance.
• Online forums and image databases: Compare potential finds with authenticated examples before you buy. If a “double die” you’re examining doesn’t match any known variety, it’s far more likely to be machine doubling damage. A quick image search can save you from an expensive mistake.

Conclusion: The Richmond Show Is Your Next Big Find Waiting to Happen

The Richmond Coin Club Show on April 30 – May 2, 2026 at the AccA Shriners Center (1712 Bellevue Ave., Richmond, VA 23227) represents exactly the kind of opportunity that error coin hunters live for. With 57 dealer tables, free admission and parking, free appraisals, and ANACS on-site accepting submissions, the infrastructure is in place for you to find, authenticate, and capitalize on rare die varieties and mint errors.

The coins are there. The 1806-dated early American piece with its historical significance and striking anomalies. The GSA 1880-CC Morgan with hundreds of known VAM varieties, some still hiding in original government holders. The Peace dollar with potential RPMs that the previous owner never thought to check. These are the kinds of coins that patient, knowledgeable hunters are finding at this show year after year. The bargain bins with their 20% discounts are where dealers unknowingly place errors they haven’t identified. The foreign and ancient tables hold brockages and double strikes that most American-focused collectors walk right past.

The difference between a collector who goes home empty-handed and one who finds a coin worth ten times what they paid comes down to three things: preparation, magnification, and the willingness to examine every single coin that crosses your path. Bring your loupes. Bring your references. Bring your cash and your trades. And most importantly, bring your knowledge of die cracks, double dies, mint mark variations, and the full spectrum of mint errors that turn ordinary pocket change into numismatic treasures with real collectibility and lasting value.

For more information about the show, contact Bill Scott at 804-350-1140 or woscott1@gmail.com, and visit https://richmondcoinclub.com/ for updates. I’ll be there Thursday morning, submitting varieties and hunting errors. I’ll see you at the tables.

Thursday & Friday 10AM – 6PM | Saturday 10AM – 5PM | Free Admission, Free Parking, Free Appraisals
