The Top 5 Costly Mistakes New Collectors Make at the Texas Coin & Currency Show — And How to Avoid Them

We all make mistakes when we start collecting, but some are more expensive than others. Here is how to avoid the classic traps with this piece.

The Texas Numismatic Association’s annual coin and currency show is right around the corner, scheduled for May 15–17, 2026, at the Will Rogers Center in Fort Worth. If you’re planning to attend — whether you’re driving in from Dallas, flying in from out of state, or even tying the show into a broader vacation — you’re in for a treat. This has always been one of the best regional shows in the South, very well put on, with a strong dealer base and educational programming like the Daniel Carr/Moonlight Mint presentation that always draws a crowd.

But here’s the thing I’ve learned after decades of walking the bourse floor: the biggest threat to your wallet isn’t the price of the coins. It’s the mistakes you make when you buy them. Every year I watch new collectors — and even some experienced ones — fall into the same five traps. Let me walk you through each one so you can walk into Fort Worth with your eyes open and your checkbook intact.

Mistake #1: Buying Cleaned Coins Without Realizing It

This is, without question, the single most expensive mistake a collector can make, and it happens at every show, including Texas. I cannot tell you how many times I’ve had a young collector bring me a Morgan dollar or an Indian Head cent, eyes wide with excitement, only to hold it under my loupe and see the telltale signs of a past cleaning.

What Does a Cleaned Coin Look Like?

Over the years, I’ve examined thousands of coins that have been cleaned, and the signs become second nature once you know what to look for. Here are the most common red flags:

• Hairline scratches: Fine, parallel lines across the surface, often visible only at certain angles under light. These come from abrasive polishing or wiping with a cloth.
• Unnatural luster: A coin that looks too bright, too white, or too uniform. Original mint luster has a cartwheel effect — it rolls across the surface as you tilt the coin. Cleaned coins often have a flat, lifeless, or overly glossy appearance.
• Discoloration patterns: Streaks or uneven toning that suggest chemical dipping. A coin that’s been over-dipped will appear chalky or overly pale, especially on copper and silver issues.
• Loss of detail: On high-relief areas like the hair on a Liberty Head design or the feathers on an eagle, aggressive cleaning will soften the sharpness of the strike.
• Micro-pitting: Under magnification, you may see tiny pits or roughness on the surface where the metal has been etched by harsh chemicals.

Why It Matters So Much

A cleaned coin is a damaged coin in the eyes of the grading services and the market. The difference in numismatic value between an original, uncleaned coin and a cleaned example of the same type can be staggering. Take, for example, a 1909-S VDB Lincoln cent. In PCGS MS-65 Red, an original coin might fetch $1,500 or more. The same coin, if flagged as cleaned by PCGS or NGC, might struggle to bring $200. That’s not a typo. You’ve just lost over 85% of the value.

At a show like the Texas event, you’ll see coins in every condition and from every era of numismatics. Some dealers are meticulous about disclosing cleaning. Others are not. And some simply don’t know — they inherited a collection or bought a lot at auction and never had the coins properly evaluated.

Actionable Takeaway

Bring a good loupe — at minimum 10x — and learn to use it before you go. Tilt every coin under the light. Look for that cartwheel luster. If something looks too good to be true, or if the surface seems “off” in any way, walk away or negotiate aggressively. When in doubt, stick with slabs from PCGS, NGC, or ANACS, which will clearly note cleaning on the label.

Mistake #2: Overpaying for Common Dates

This one is a rite of passage for almost every collector, and I’ll be honest — I did it myself when I was starting out. You see a beautiful Morgan dollar, or a Mercury dime, or a Walking Liberty half dollar, and you assume that because it’s old, it must be valuable. Not necessarily.

The Difference Between a Key Date and a Common Date

In virtually every series, there are key dates and semi-key dates that command significant premiums, and then there are common dates that are, well, common. Here are some examples that are relevant to what you’ll find at the Texas show:

• Morgan Dollars (1878–1921): The 1893-S, 1895 (Philadelphia, no mint mark), and 1889-CC are legendary rarities. But the 1881-S, 1882-S, 1883-O, 1884-O, 1885, and 1885-O are among the most common dates in the series, often available in mint condition for $30–$60. Yet I’ve seen new collectors pay $100 or more for an 1881-S Morgan in MS-63 simply because it looked “old and shiny.”
• Mercury Dimes (1916–1945): The 1916-D is the king of the series. The 1921 and 1921-D are also scarce. But dates like the 1938, 1939, 1940, 1941, 1942, 1943, and 1944 are extremely common in all grades and can often be bought in mint condition for under $15.
• Walking Liberty Half Dollars (1916–1947): The 1916, 1916-D, 1916-S, 1921, 1921-D, and 1921-S are the keys. But the 1941, 1942, 1943, 1944, 1945, 1946, and 1947 are abundant and affordable.
• Lincoln Cents (1909–present): The 1909-S VDB, 1914-D, 1922 No D, and 1955 Doubled Die are the famous rarities. But the vast majority of Wheat cents from the 1930s and 1940s are common dates worth only a few cents to a few dollars.

How to Protect Yourself

Before you go to the show, do your homework. Pick up a copy of the Guide Book of United States Coins (the “Red Book”) or use online resources like PCGS CoinFacts, NGC Coin Explorer, or the US Mint’s own historical pages. Look up the mintage figures and current retail values for the dates you’re interested in. If a dealer is asking $75 for a coin that retails for $30 in the same grade, you need to ask yourself why.

Also, be aware that some dealers will try to sell common-date coins in attractive toning or in old holders at a premium. A beautifully toned 1943 Mercury dime is still a common date. The toning may add some eye appeal, but it doesn’t transform a $5 coin into a $50 coin.

Actionable Takeaway

Make a want list before the show. Research every date on that list. Know the approximate retail value in the grades you’re targeting. And don’t be afraid to walk away from a deal that doesn’t feel right. There will always be another coin.

Mistake #3: Trusting Bad Holders

This is a subtle one, and it trips up even experienced collectors. Not all holders are created equal, and not all grading is reliable.

The Problem with “Off-Brand” Slabs

The gold standard in third-party grading is PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company). These two services have been grading coins for decades, have consistent standards, and their slabs are widely accepted in the marketplace. ANACS (American Numismatic Association Certification Service) is also well-respected, particularly for its historical role as the first third-party grading service.

But there are other holders out there — and I’ve seen them at the Texas show — that should make you very cautious:

• ICG (Independent Coin Graders): While ICG has its defenders, the market generally does not value ICG-graded coins at the same level as PCGS or NGC. In my experience grading and reselling coins, an ICG MS-65 will typically bring 10–20% less than the same coin in a PCGS or NGC holder of the same grade.
• PCI (Photographic Certification Inc.): PCI was a grading service that operated in the 1990s and early 2000s. Their slabs are notorious for overgrading. I’ve seen PCI MS-67 coins that I would grade no higher than MS-63 or MS-64 by current standards. Avoid these entirely.
• SEGS (Southeastern Grading Service): SEGS has a small following, but their market acceptance is limited. Coins in SEGS holders often need to be resubmitted to PCGS or NGC to achieve full market value.
• Raw coins in homemade or generic holders: Some dealers will place a raw coin in a generic plastic holder with a handwritten or printed label claiming a grade. These are essentially worthless as a guarantee of authenticity or grade.

Why the Holder Matters

The holder is your guarantee. When you buy a coin in a PCGS or NGC slab, you’re paying not just for the coin but for the assurance that the coin is genuine, accurately graded, and properly described. If the coin is later found to be counterfeit or overgraded, both PCGS and NGC have guarantee programs that will make you whole.

With off-brand slabs, you have no such guarantee. And at a show, where you may not have the time or equipment to fully evaluate a coin before purchasing, the holder is your first line of defense.

Actionable Takeaway

Stick with PCGS, NGC, or ANACS for your major purchases. If you’re considering a coin in an off-brand holder, either negotiate a significant discount to account for the risk, or plan to have the coin resubmitted to a major service. And always, always verify the coin against the grading service’s online database — both PCGS and NGC offer free verification tools where you can enter the serial number and confirm that the coin matches the label.

Mistake #4: Falling for Marketing Hype

The coin market is not immune to marketing, and at a show like the Texas event, you’ll encounter it in many forms. Some of it is legitimate — a dealer highlighting the genuine rarity and historical significance of a coin. But some of it is pure hype designed to separate you from your money.

Common Hype Tactics to Watch For

Here are the marketing tricks I’ve seen over and over again:

• “Investment-grade” coins: Every dealer wants you to believe that the coin you’re about to buy is a surefire investment. The truth is, coins are not stocks. They don’t pay dividends. Their value depends on collector demand, which can fluctuate. A coin that’s “investment-grade” today may be less desirable in five years if the market shifts.
• “Last one” or “rare opportunity” pressure: If a dealer tells you that this is the last coin of its kind they’ll ever have, or that someone else is coming back for it at 3 PM, be skeptical. There are millions of coins in the market. There is always another opportunity.
• Special mint sets and commemoratives: The U.S. Mint and private mints like the Moonlight Mint (which will have a presentation at the Texas show) produce beautiful products. But beauty does not equal rarity or investment potential. Many modern commemoratives and special sets are produced in large quantities and never appreciate significantly beyond their issue price.
• “VAM” or variety hype: VAMs (Van Allen-Mallis varieties) are die varieties of Morgan and Peace dollars that are collected by specialists. Some VAMs are genuinely rare and valuable. But many are common, and I’ve seen dealers hype minor die cracks or doubling as “rare VAMs” to justify a premium. If you’re not a VAM specialist, be very cautious about paying extra for a variety attribution.
• Unrealistic grade claims: A dealer who tells you that a circulated coin is “almost uncirculated” or that a coin in a no-name holder is “solid MS-65 quality” is trying to inflate the perceived value. Trust your own eyes and your own research.

The Daniel Carr / Moonlight Mint Factor

Speaking of the Moonlight Mint presentation at the Texas show — Daniel Carr is a talented designer and engraver whose work is genuinely beautiful. His designs, including the amero patterns and various fantasy pieces, have a dedicated following. But it’s important to understand what you’re buying. These are private mint products, not U.S. government issues. They have a place in the market, but their value is driven entirely by collector demand for the specific design and metal content, not by any government backing or legal tender status. Enjoy them for what they are, but don’t confuse them with rare U.S. coinage.

Actionable Takeaway

Before you buy anything at the show, ask yourself: “Am I buying this because I genuinely want it and understand its value, or because someone is telling me I should want it?” If the answer is the latter, put your wallet away and keep walking.

Mistake #5: Not Setting a Budget (and Sticking to It)

This is the mistake that ties all the others together. Every single trap I’ve described — cleaned coins, common dates, bad holders, marketing hype — becomes more dangerous when you haven’t set a budget.

Why Budgets Matter at Shows

A coin show is an exciting environment. There are hundreds of tables, thousands of coins, and dozens of dealers all competing for your attention. It’s easy to get caught up in the moment and overspend. I’ve seen collectors blow through a $500 budget in the first hour and then spend the rest of the show regretting it.

How to Set and Stick to a Budget

1. Decide your total budget before you arrive. Write it down. Put the cash in an envelope if that helps. If you’re using a debit or credit card, set a hard limit and don’t exceed it.
2. Allocate your budget by category. For example, if you have $1,000, you might allocate $400 for Morgan dollars, $300 for type coins, $200 for currency, and $100 for “fun money” — coins that catch your eye but aren’t on your want list.
3. Walk the entire floor before buying anything. This is the single best piece of advice I can give you. Do a full lap of the bourse floor. Look at everything. Take notes. Compare prices. Then go back and make your purchases.
4. Bring a buddy. If you’re going with a friend — like the collector from Dallas mentioned in the forum thread — hold each other accountable. A good collecting partner will tell you when you’re about to make a mistake.
5. Don’t be afraid to negotiate. At most shows, dealers expect some haggling. If a price seems high, make a reasonable counteroffer. The worst they can say is no.

Actionable Takeaway

Your budget is your shield against every mistake on this list. Set it before you go, write it down, and stick to it. You’ll thank yourself on the drive home.

Bonus Tip: Know the Show Logistics

A few practical notes for the Texas Coin & Currency Show:

• Venue: The show will be at the Will Rogers Memorial Center in Fort Worth, TX. This venue has been confirmed for the next few years, so if you can’t make it in 2026, you’ll have future opportunities.
• Dates: May 15–17, 2026. Friday through Sunday.
• Location history: The show has rotated through various Texas cities over the years — Arlington for about a decade, then two years in Conroe (about an hour outside Houston), and now back in the DFW metroplex. It’s a well-established show with a strong reputation.
• Check the TNA website: For the most current information on hours, admission, dealer lists, and special events like the Daniel Carr/Moonlight Mint presentation, visit texasnumismatics.org.

Conclusion: Collect Smart, Collect Long

The Texas Coin & Currency Show is one of the best regional numismatic events in the country, and it’s a fantastic place to build your collection, learn from experienced dealers and fellow collectors, and find coins that you’ll treasure for years. But the bourse floor is also a place where costly mistakes happen every day — to new collectors and veterans alike.

The five mistakes I’ve outlined here — buying cleaned coins, overpaying for common dates, trusting bad holders, falling for marketing hype, and failing to set a budget — are the ones I see most often, and they’re the ones that cause the most financial pain. Every one of them is avoidable with a little knowledge, a little discipline, and a good loupe.

Numismatics is one of the most rewarding hobbies in the world. Every coin has a story — a story about the era it was minted, the hands it passed through, and the history it witnessed. When you collect wisely, you’re not just accumulating metal. You’re preserving history. And that’s worth getting right.

So do your homework before May 15th. Make your want list. Set your budget. Charge your phone (for looking up values on the bourse floor). And when you walk into the Will Rogers Center, walk in with confidence — because you’ll know exactly what to look for, and exactly what to avoid.

See you on the bourse floor.
