Rare coin scams cost American investors millions of dollars every year. Mostscams follow predictable patterns — and they are entirely avoidable once youknow what to look for. Sovereign Numismatics publishes this guide becauseprotecting investors protects the industry.

The Most Common Rare Coin Scams

1. Overgraded Raw Coins Sold as "Investment Grade"

The most widespread scam in numismatics. A dealer sells raw (uncertified)coins with inflated grade claims — calling an AU58 coin "Mint State" or acleaned coin "original." Without PCGS or NGC certification, the buyer has noobjective standard. This scam is eliminated entirely by purchasing onlycertified coins.

2. Extreme Markup Over Wholesale Value

Some firms sell PCGS/NGC certified coins at 50–200% above Greysheetwholesale value. The coins are genuine and properly graded — but grosslyoverpriced. Always ask to see the Greysheet value before purchasing. Areasonable retail markup is typically 10–25% above wholesale depending onthe coin's rarity and grade.

3. Bait-and-Switch on "Rare" Dates

A dealer promotes a specific coin at an attractive price, then claims it soldand steers the buyer toward a di!erent, higher-priced coin. Legitimatedealers honor their quoted prices and maintain inventory they actually hold.

4. Pressure to Buy Immediately

Phrases like "this coin won't last," "prices are going up tomorrow," or "I'mholding this for you but I have other buyers" are classic high-pressure tactics.Certified rare coins are a long-term market. Any dealer creating artificialurgency is not acting in your interest.

Red Flag: Any dealer who refuses to provide Greysheet wholesale values,discourages you from getting a second opinion, or pressures you to decideimmediately should be avoided. Legitimate dealers welcome informed buyers.

How to Protect Yourself

Buy only PCGS or NGC certified coins. Verify Greysheet wholesale valuesbefore purchasing. Confirm a written return policy before sending payment.Check the dealer's ANA/PNG membership. Research the dealer online andwith the Better Business Bureau. Consult a second dealer for a pricingopinion on any purchase over $5,000.

The rare coin industry has both exceptional professionals andpredatory operators. !e di"erence is certification, transparentpricing, and willingness to be held accountable. SovereignNumismatics welcomes scrutiny because legitimate dealers havenothing to hide.
