The Importance of Provenance: Tracking the History of 1922 Weak D Lincoln Cents and the PCGS Numbering Puzzle
May 9, 2026The Currency Connection: Paper Money from the Era of Modern BU Roll Coin Hunting
May 9, 2026With counterfeits flooding the market at an unprecedented rate, knowing the specific diagnostic points for any coin you’re about to buy isn’t optional — it’s survival. Every year, thousands of collectors descend on regional coin shows across the United States, and the Texas Numismatic Association’s annual show — held this year in Fort Worth on May 15–17, 2026 — is no exception. It’s one of the premier events in the South Central region, drawing dealers, auction houses, and hobbyists from across the country. But with that volume of commerce comes real risk. I’ve examined hundreds of pieces pulled from show floors over the course of my career, and I can tell you without hesitation: the Texas show, like any major numismatic event, is a magnet for counterfeit coins, altered dates, and deceptive reproductions.
In my twenty-plus years of grading and authenticating coins, I’ve watched the sophistication of fakes increase dramatically — especially in the last decade. What used to be easy-to-spot cast copies are now high-pressure struck counterfeits that can fool even seasoned collectors with sharp eye appeal. That’s exactly why I put together this authentication guide. It’s built around five diagnostic pillars every buyer should internalize before purchasing at the Texas Coin & Currency Show — or any similar event, for that matter. We’ll cover weight, magnetic properties, die markers, the most common fakes circulating today, and the testing methods you can deploy right at the bourse floor. No lab required.
Why the Texas Coin & Currency Show Demands Extra Vigilance
The Texas Numismatic Association show has a long and storied history. For roughly a decade, the event called Arlington, Texas, home. When that facility closed, the show relocated to Conroe — about an hour outside Houston — for two years before returning to the Dallas–Fort Worth metroplex. The 2026 edition is being held at the Will Rogers Memorial Center in Fort Worth, a venue the TNA is expected to use for the next several years.
Here’s what that rotation means for you as a buyer: the show attracts a wide and sometimes inconsistent mix of dealers. You’ll find the most reputable numismatic firms alongside transient vendors who may not have the expertise — or the integrity — to guarantee authenticity. That variability is precisely why you need to come prepared.
The show also features special presentations, including a Daniel Carr / Moonlight Mint session that draws significant attention every year. Carr’s work — particularly his designs for the private-mint and bullion communities — is highly collectible and, unfortunately, frequently counterfeited. If you’re attending the show to acquire pieces like these, or any classic U.S. coins, foreign currency, or historical relics, you need to walk in with a plan. Not a vague intention — a concrete, step-by-step authentication strategy.
Diagnostic Pillar #1: Weight — The First and Most Fundamental Test
Weight is the single most reliable first-pass authentication tool available to any collector, and it requires nothing more than a precision scale. I always carry a digital scale accurate to 0.01 grams in my show bag. Always. Here’s why weight matters so much:
- Genuine U.S. silver dollars (Morgan and Peace dollars) should weigh 26.73 grams. A deviation of more than 0.3 grams is a red flag — put it back.
- U.S. gold coins — for example, a $20 Saint-Gaudens double eagle — should weigh 33.44 grams. Counterfeits frequently come in underweight because the faker uses a base-metal core plated with gold.
- Modern bullion, such as American Silver Eagles, should weigh exactly 31.10 grams (1 troy ounce). I’ve personally weighed “Silver Eagles” at shows that came in at 28 or 29 grams — clear indicators of tungsten-core fakes.
The principle is straightforward: counterfeiters rarely match the exact weight of a genuine coin because they use cheaper metals with different densities. A tungsten core, for instance, can approximate the weight of gold (tungsten is about 97% the density of gold), but it will almost never be exact — and it will fail other tests we’ll discuss below. Weight is your gatekeeper. If a coin doesn’t pass this test, nothing else matters.
How to Weigh Coins at a Show
Bring your own scale. Don’t rely on a dealer’s scale, and don’t assume the coin “feels right.” Human hands are terrible at detecting weight differences of less than 5%. A pocket digital scale costs between $15 and $30 and is one of the best investments you’ll ever make in this hobby. Weigh the coin, compare it to the official specifications published by the U.S. Mint or in the Guide Book of United States Coins (the “Red Book”), and move on to the next test if — and only if — the weight checks out.
Diagnostic Pillar #2: Magnetic Properties — A Quick and Devastating Test
This is the test that instantly exposes the most common category of counterfeit: coins made from magnetic base metals. Genuine gold and silver coins are not magnetic. Period. If a coin sticks to a magnet — or even shows slight magnetic attraction — it is not a genuine precious-metal coin. End of discussion.
I use a small neodymium magnet (about the size of a dime) that fits in my pocket. Here’s what different magnetic responses tell you:
- Strong attraction: The coin is made of a ferromagnetic metal like iron, nickel, or steel. This is an obvious fake for any gold or silver coin.
- Weak or slight attraction: Some counterfeits use alloys that have minor magnetic properties. This is still a fail. Genuine silver and gold exhibit zero magnetic attraction — none.
- No attraction: This is necessary but not sufficient. A non-magnetic fake can still exist (copper-core, lead-core, or tungsten-core coins are all non-magnetic). You’ll need additional tests to be sure.
One important caveat: some genuine coins are magnetic. U.S. steel cents from 1943, certain foreign coins, and some modern circulation coins contain magnetic metals. Know what you’re buying before you apply this test. But for any coin that should be silver or gold, magnetism is an instant disqualifier. It takes two seconds and can save you hundreds — or thousands — of dollars.
Diagnostic Pillar #3: Die Markers — The Fingerprint of Authenticity
This is where authentication moves from basic screening into expert territory. Every genuine coin is struck by a pair of dies — hardened steel cylinders engraved with the coin’s design. Over the course of production, those dies develop unique characteristics: cracks, polishing marks, clash marks, and other imperfections that are transferred to every coin they strike. These are called die markers, and they are essentially the fingerprint of a genuine coin.
Counterfeiters create their own dies, and those dies have their own markers — which are different from the genuine article. Learning to identify die markers is one of the most powerful skills a collector can develop. It transforms you from a passive buyer into an active authenticator.
Key Die Markers to Examine
- Die cracks: Thin raised lines on the coin’s surface that result from the die cracking under the immense pressure of the coining press. Genuine die cracks have a specific appearance — they’re sharp, raised, and follow the contour of the design. Fake die cracks (added by the counterfeiter to mimic age) often look etched or irregular.
- Die polish lines: Fine parallel lines visible under magnification, caused by mint workers polishing dies to remove clash marks or other imperfections. These lines have a specific directionality and depth that’s difficult to replicate convincingly.
- Repunched mint marks (RPMs): On older U.S. coins, mint marks were punched into the die by hand. Sometimes the punch was misaligned and had to be repunched, creating a doubled image. These are well-documented for many issues and serve as critical authentication markers — and they’re a big part of what gives certain rare variety coins their numismatic value.
- Die deterioration doubling (DDD): As dies wear near the end of their life, they can produce a form of doubling that’s distinct from genuine hub doubling. Knowing the difference is essential for authenticating key dates and avoiding expensive mistakes.
For Morgan dollars — one of the most commonly counterfeited series in existence — the VAM (Van Allen-Mallis) system catalogs thousands of die varieties. If you’re buying a VAM-listed Morgan dollar at the Texas show, cross-reference the die markers with the VAM reference before you hand over your money. I’ve seen counterfeit “rare VAMs” on bourse floors that don’t match a single documented die marker. Not one.
Diagnostic Pillar #4: Common Fakes Circulating at Shows Like the TNA Event
Over the years, I’ve compiled a mental catalog of the fakes I encounter most frequently at regional shows. The strike quality has gotten better, but the tells are still there if you know where to look. Here are the ones you’re most likely to see at the Fort Worth event:
1. Chinese-Struck Morgan and Peace Dollars
These are the single most common counterfeit coins in the U.S. market. They’re produced in large quantities, often with convincing weight and diameter. However, they typically exhibit:
- Incorrect or mushy details in the hair and feather design elements — the fine lines lack sharpness
- Wrong style of mint mark (the font and placement don’t match genuine issues)
- Unusual luster — often too “satiny” or too “cartwheel” compared to genuine mint luster, which has a distinctive character that’s nearly impossible to fake
- Edge reeding that’s inconsistent with the genuine coin (wrong number of reeds, uneven spacing)
2. Counterfeit American Gold Eagles
Gold Eagles are heavily counterfeited, particularly the 1-ounce size. The collectibility of these coins makes them a prime target. Common tells include:
- Slightly off weight (even by 0.5 grams — that’s why your scale matters)
- Soft details on Liberty’s torch and the eagle’s feathers — genuine pieces show crisp, well-defined strike quality
- Color that’s too pale or too orange (genuine Gold Eagles have a specific rose-gold hue from their copper alloy content)
- Incorrect date font or spacing — compare against a known genuine example
3. Fake Daniel Carr / Moonlight Mint Pieces
Given that the 2026 TNA show features a Daniel Carr presentation, expect to see his work on the bourse floor. Carr’s designs — including his famous “private” $20 gold piece and various bullion designs — are widely reproduced. Key authentication points:
- Verify the exact diameter, weight, and thickness against Carr’s published specifications
- Examine the edge lettering or design — Carr’s pieces often have distinctive edge treatments that fakers consistently get wrong
- Check for the correct finish (proof, reverse proof, or bullion) — counterfeits often have an inconsistent or incorrect surface finish that affects both luster and eye appeal
- Purchase only from authorized dealers or with a certificate of authenticity directly traceable to the Moonlight Mint — provenance matters here more than almost anywhere else
4. Altered Dates and Added Mint Marks
Not all fakes are struck from scratch. Some of the most insidious alterations involve taking a common-date coin and modifying it to appear rare. A common 1884-S Morgan dollar, for example, might have an “S” mint mark added to make it appear to be the rare 1884-S in mint state. Under magnification, added mint marks show:
- Tool marks or scratches around the mint mark — the surrounding patina will be disturbed
- Different color or luster in the mint mark area (indicating solder or filler material)
- Incorrect font or positioning relative to the genuine mint mark location — this is often the dead giveaway
Diagnostic Pillar #5: Testing Methods You Can Use at the Show
You don’t need a laboratory to perform effective authentication at a coin show. But you do need the right tools — and the discipline to use them on every coin that isn’t already certified. Here’s the kit I recommend every collector carry:
Essential Field Authentication Kit
- 10x loupe or triplet magnifier: For examining die markers, surface details, and edge characteristics. A triplet loupe (three lenses cemented together) provides superior color correction and is worth the extra cost.
- Digital scale (0.01g precision): For weight verification, as discussed above. Non-negotiable.
- Neodymium magnet: For magnetic testing. A small disc magnet is sufficient and fits in your pocket.
- Calipers or digital micrometer: For measuring diameter and thickness. Counterfeits are often slightly off in one dimension even if they match in another.
- Reference book or smartphone with Red Book data: For quick lookup of specifications when you’re unsure.
- UV flashlight (optional but useful): Some counterfeit materials fluoresce differently under ultraviolet light. Certain modern fakes will glow where genuine coins do not — a quick and revealing test.
Advanced Testing Methods
For high-value purchases — and at a show like this, that could mean anything over a few hundred dollars — consider these additional methods:
- Specific gravity testing: This involves weighing the coin in air and then in water to calculate its density. It’s the definitive test for detecting tungsten-core gold fakes, since tungsten and gold have different densities despite being close. The formula is: specific gravity = (weight in air) ÷ (weight in air – weight in water). If the number doesn’t match the expected specific gravity of the metal, walk away.
- Ultrasonic testing: Portable ultrasonic testers can detect internal inconsistencies, such as a base-metal core plated with a precious metal. These devices measure the speed of sound through the metal, which varies by material. They’re becoming more affordable and more common at shows.
- X-ray fluorescence (XRF): Some larger shows now have dealers or third-party services offering on-the-spot XRF analysis. This non-destructive test gives you an exact elemental breakdown of the coin’s surface. It’s the gold standard (no pun intended) for field authentication, and I’d love to see it become standard practice at every major show.
Red Flags to Watch for at the Texas Show
Beyond the technical tests, there are behavioral and situational red flags that should make you pause — or simply walk away — before buying. I’ve learned to trust these instincts over the years:
- Dealer won’t let you test the coin: Any reputable dealer will allow you to weigh, measure, and examine a coin under magnification. If they resist, make an excuse and leave. Seriously.
- Pressure to buy immediately: “This price is only good today” or “Another buyer is coming back” are classic pressure tactics. A genuine rare coin in mint condition will still be available after you’ve had it authenticated. If it’s truly rare, it’ll find another buyer — and you’ll find another coin.
- No third-party grading: For any coin over $200, I strongly recommend buying only PCGS-, NGC-, or ANACS-graded coins in certified slabs. If a dealer is selling raw coins at premium prices, the risk increases significantly — and so should your skepticism.
- Prices that seem too good to be true: They are. A mint-state 1909-S VDB Lincoln cent carries significant numismatic value — we’re talking $700 and up. If someone offers you one for $150, it’s fake. Every single time.
- Unfamiliar dealer with no established reputation: At a show like the TNA event, where the venue rotates and the dealer mix changes, be extra cautious with vendors you can’t verify through the American Numismatic Association, the Better Business Bureau, or established collector forums. A dealer’s reputation is part of a coin’s provenance.
What to Do If You Suspect a Fake
If you encounter a coin at the Texas show that you believe is counterfeit, here’s my recommended course of action. Stay calm, stay professional, and do the right thing:
- Don’t confront the dealer aggressively. Simply decline the purchase and move on. Heated confrontations help no one and can escalate quickly in a crowded venue.
- Document the coin. Take photos, note the dealer’s name and booth number, and record the asking price. This information is invaluable for any follow-up investigation.
- Report it. Notify the show organizers. The Texas Numismatic Association takes counterfeiting seriously and will investigate. You can also report suspected counterfeits to the ANA or, for high-value items, to the U.S. Secret Service — which has jurisdiction over counterfeiting of U.S. currency.
- Share the information. Post on collector forums (anonymously if you prefer) to warn other collectors. The numismatic community is its own best defense against counterfeiters, and information sharing is how we protect each other.
Conclusion: Protecting Yourself and the Hobby
The Texas Numismatic Association’s annual show is one of the great traditions of American numismatics. It’s a place where lifelong collections are built, rare finds are made, and the community comes together to celebrate the history and artistry of coinage. The 2026 edition in Fort Worth promises to be another excellent event, with presentations like the Daniel Carr / Moonlight Mint session adding educational value to the bourse floor experience.
But the reality of modern numismatics is that counterfeits are more prevalent and more sophisticated than ever. The five diagnostic pillars I’ve outlined — weight, magnetic properties, die markers, awareness of common fakes, and practical testing methods — are your best defense. Carry your kit, trust your instincts, and never let excitement override diligence. The coins with the best eye appeal and the strongest provenance will still be there after you’ve done your homework.
I’ve been attending shows like this for over twenty years, and the collectors who consistently make smart purchases — who build collections with lasting numismatic value — are the ones who do their homework before they ever set foot on the bourse floor. Study the coins you want to buy. Learn their die markers. Know their specifications by heart. Understand what genuine luster looks like versus what a fake can produce. And when in doubt, walk away — or send the coin to PCGS or NGC for professional authentication before you commit a single dollar.
The hobby is only as strong as the trust that underpins it. By arming yourself with knowledge and testing tools, you’re not just protecting your own collection — you’re helping protect the integrity of numismatics for everyone. That’s a responsibility every collector shares, and it starts with the decisions you make at the bourse floor. See you in Fort Worth.
