October 27, 2025I’ve Watched Collectors Lose Thousands – Don’t Make These 5 Coin Show Mistakes
After 15 years hunting coins at Manchester NH shows, I’ve seen the same five errors drain wallets faster than a slot machine. That excited rush when you spot “new gold” can blind even seasoned collectors. Let me show you where buyers stumble and exactly how to sidestep these traps.
Mistake 1: Falling for Pretty Faces Without Proof
Why “It Looks Genuine” Isn’t Good Enough
Last spring at Manchester, I watched a collector drop $2,800 on an “1861 gold piece” – later revealed as a skilled Chinese fake. My gut knew something was off: the eagle’s wing feathers looked mushy under my loupe. Never buy gold coins without checking:
- Edge lettering alignment (grab a 10x loupe)
- Exact weight (carry a pocket scale – real gold doesn’t lie)
- Magnet test (gold should never stick)
My 3-Minute Reality Check
When I spot a potential buy, I always:
- Verify certification on NGC/PCGS apps immediately
- Compare to authenticated coins using CoinFacts
- Get written guarantees – no paper, no deal
Mistake 2: Paying Top Dollar for Common Coins
The Red Flag Every Collector Misses
That “rare” 1890-CC Morgan? In well-worn G-4 condition, it’s actually pretty common. I’ve watched folks pay 40% above market value just because the coin looked “cool.” Always:
- Check real-time Grey Sheet bids on your phone
- Review recent Heritage Auction prices
- Calculate melt value for gold coins first
The Coin Show Price Formula That Works
Smart Price = (Grey Sheet Bid × Condition) + Max 15% “Show Tax”
Example: An MS-64 1884-CC Morgan priced at $2,500? Grey Sheet says $1,850 – with 10% show premium, you shouldn’t pay over $2,035.
Mistake 3: Forgetting Fingerprints Are Forever
The Invisible Value Killer
Those bare-handed collectors oohing over Morgans? They’re leaving $200 value drops with every fingerprint. Protect your buys:
- Use nitrile gloves (cotton leaves fibers)
- Keep drinks three tables away
- Bring snap-tight holders for safe transport
Oops, I Touched It! Now What?
If skin hits a proof surface:
- Freeze – no wiping!
- Pure acetone soak (drugstore grade works)
- Distilled water rinse
- Air dry on microfiber cloth
Mistake 4: Buying “Original” Stories
When “Untouched” Means “Artificially Aged”
Dealers love pushing “original surface” Morgans – but I’ve seen chemical dips create those “natural” rainbows. Watch for:
- Straight-line toning (real patina flows randomly)
- Cloudy surfaces (dip residue)
- Over-darkened edges (common in fakes)
My Show Floor Lighting Trick
Spot doctored coins in seconds:
- Tilt coin 45 degrees
- Shine phone light across surface
- Look for sanding marks
- Check for hairlines with loupe
Mistake 5: Buying Without an Escape Plan
Why “Cool” Coins Make Bad Investments
That collector who traded an MS Morgan for a “rare” low-grade piece? Unless it’s a key date, they just killed resale value. Always ask:
- Can I flip this quickly? (Bid-ask over 25% = trouble)
- Who actually buys these?
- How often do they sell at auction?
The 4-Point Liquidity Test
Only buy coins that pass:
- At least 5 dealers trade this series
- Sells 3+ times/year at major auctions
- PCGS/NGC population under 500
- Grey Sheet rating B+ or higher
Your Manchester Coin Show Must-Haves
Never walk the floor without:
- Precision scale (0.01g accuracy)
- 10x loupe with light
- Nitrile gloves in your back pocket
- Grey Sheet access on your phone
- UV flashlight for spotting glue
Become the Collector Who Always Wins
Manchester NH coin shows offer incredible finds – if you dodge these five traps. Remember: trust scales over stories, liquidity over looks, and always pack your loupe. Follow these steps and you’ll leave with treasures – not regrets.
