What I Check Before Selling Coins to a Dealer

The first time I sold coins to a dealer, I walked out feeling vaguely cheated even though I'd accepted the offer willingly. I didn't know enough to know I didn't know enough. Since then I've developed a routine before I hand anything over, and the difference in outcomes has been significant.

Know what you have before anyone else tells you

The single biggest mistake sellers make is walking into a coin shop cold. If you don't have at least a rough idea of your coin's grade and ballpark value, you have no footing to evaluate any offer. A coin price guide runs ten to thirty dollars and pays for itself immediately. The Red Book for US coins is the standard reference — it's not perfect, but it gives you a defensible floor. Online resources like PCGS CoinFacts list recent auction results so you can see what similar pieces actually sold for, not what someone hopes to get.

Grade matters enormously. A coin in Fine condition might be worth a few dollars; the same coin in Mint State could be worth hundreds. A basic coin grading guide helps you place your piece roughly on the spectrum before a dealer weighs in. You don't need to nail the exact grade — you just need to know whether you're in the "circulated and common" bucket or something more interesting.

Check dealer credentials before you make an appointment

The Professional Numismatists Guild is the relevant body for US dealers. Membership requires adherence to a code of ethics and some minimum standards of conduct. It's not a guarantee of a great deal, but it does mean there's a formal complaint mechanism if something goes wrong. Look for PNG membership on the dealer's website or ask directly. The American Numismatic Association also maintains a directory.

Coin shop reviews on Google and Yelp tell you something about how disputes get handled, which is more useful than five-star reviews praising how "nice" the staff was. What you want to see is patterns: do sellers report lowball offers with no explanation, or does the dealer at least walk through the reasoning? A dealer who explains their math is one you can negotiate with.

Get more than one offer

This sounds obvious but most people don't do it. A single offer feels like the market. Three offers actually tell you where the market is. Because dealers factor in different profit margins depending on what they need for inventory, the spread between the highest and lowest offer on the same coin can be surprising — sometimes 30 to 40 percent on a moderately valuable piece.

If you have a coin collection album with multiple pieces, bring photos of the full set rather than individual coins on a first visit. Some dealers will pay a premium for a complete or near-complete set because it saves them assembly time. Others just want the cherries. Knowing which type you're dealing with affects strategy.

Understand the business model, don't fight it

Dealers buy at wholesale and sell at retail. That's the arrangement. They're not stealing from you when they offer 60 percent of retail value — that margin is how they keep the lights on. What would be unreasonable is offering 20 percent of retail on a coin they can quickly flip for full catalog price. Understanding the difference requires knowing what coins are genuinely in demand locally versus what sits in cases for months.

Common date silver dollars in circulated condition are plentiful. A dealer who says they can only offer melt value on a 1921 Morgan is probably right — there are plenty of those and buyers aren't queuing up for circulated examples. A key date coin or a strong-grade piece in a popular series is a different conversation. Bring your coin value reference and don't be embarrassed to consult it in front of the dealer.

What I'd skip

I'd skip selling at any venue where you can't take the coin back if you change your mind. Auctions at coin shows work well for higher-value pieces because there's competitive bidding pressure. But if you're walking in with a small lot of average material, the auction fees and timeline don't make sense — a direct dealer sale is simpler. I'd also skip any dealer who won't explain their grading call. "I can give you $40 for this" with no further context is not a good sign; "this grades VF-20 and that's where the market is right now" is a dealer you can work with.

The bottom line: selling coins doesn't have to feel like a coin toss. Do your research, check credentials, collect multiple offers, and bring a numismatic reference book you've actually read. The dealers who make you feel rushed or discourage questions are the ones to walk away from.
