Sell Error Coins in Denver
We buy genuine mint errors from sellers around the Denver metro, and we tell you plainly when a coin turns out to be damage instead. Each suspected error is checked under magnification in front of you before anything goes in writing.
Private appointments across the Denver metro. We call back the same business day.
How error coins are priced
A true mint error is priced on collector demand, which depends on the kind of error, how bold it is and the coin it happened to. A cent struck slightly off center and one struck halfway off the blank are very different coins. A suspected error that turns out to be damage is priced like any other coin of its date and metal.
What sets the price of an error
- The kind of error comes first, since some types are much scarcer than others.
- A bold error you can see without a loupe usually brings more than a faint one.
- The coin's own date, mint mark and grade still count.
- Damage after the coin left the Mint, plating bubbles and wear add nothing.
- A PCGS or NGC slab that names the error can make resale easier.

Selling in Denver
Why D-mint errors turn up around Denver
The Denver Mint has struck coins on West Colfax Avenue since 1906, and over that time it has turned out a huge share of the cents, nickels, dimes and quarters people carry. Any mint working at that pace lets a few mistakes slip through. So it makes sense that sellers in Lakewood, Aurora and Commerce City find odd coins with a D mint mark in their change jars.
Most of what people bring us is not a mint error, though. That is the honest answer, and we give it at the table. A coin that rode around in a cup holder for a year, went through a washing machine or got run over in a parking lot can look very strange. Videos online that promise a fortune in pocket change add to the confusion, and we see a lot of hopeful sellers because of them.
Damage happens after a coin leaves the Mint. Tires and snowplows flatten and scrape coins dropped on the street. Heat and household chemicals change the color. Cents made since 1982 are copper-plated zinc, and that thin plating can bubble, peel or turn gray. Plating trouble and heavy wear fool more people than anything else we see.
Real errors leave signs that damage cannot copy. A doubled die shows doubled letters or numbers with rounded, raised edges, because the die itself carried the doubling. An off-center strike leaves part of the design missing and a blank crescent of metal. A clipped planchet has a smooth curved bite out of the rim. A wrong-planchet strike puts one coin's design on a blank meant for another. Die cracks show as thin raised lines, and a cud is a raised blob where a piece of the die broke away at the edge.
We check each suspect coin under magnification while you watch. If it is damage, we say so and explain what we saw. If it is a genuine error, it goes on your written offer as its own line, priced on current collector demand. Some sellers choose to send a strong error to PCGS or NGC for grading before they sell, and we can talk that through.
Bring the coins loose or in flips, and please do not clean or scrape them to get a better look. Call 303-401-0104 to set up a free evaluation, and we will return your call the same business day.

Questions
Common questions
How do I know if my coin is a real error?
A real mint error happened when the coin was struck, so it follows patterns damage cannot copy. Doubled dies show raised, rounded doubling. Off-center strikes leave a blank crescent of metal, and clipped planchets have a smooth curved edge. Damage tends to look scraped, flattened or pushed. We check each coin under magnification and explain what we see.
Why do so many suspected errors turn out to be damage?
Coins take a beating once they leave the Mint. Wear, scratches, heat and chemicals can all make a coin look odd. Cents made since 1982 have copper plating over zinc, and that plating can bubble or peel. These changes look strange, but they happened outside the Mint, so collectors do not pay extra for them.
Does the Denver Mint make more errors than other mints?
We have no reason to think so. Denver strikes a lot of coins, so around the metro many of the odd coins people find carry a D mint mark. A D-mint error is priced the same way as one from any other mint, on the kind of error, how bold it is and the coin it appears on.
Should I send my error coin to PCGS or NGC first?
It depends on the coin. A strong, genuine error can be easier to sell once it sits in a slab that names the error. A minor one may not be worth the grading fee. Bring it to us first. The evaluation is free, and we can tell you whether the coin looks like a real error before you spend anything.
What happens if my coin is not an error?
You keep it, along with our written notes on what we found. If it is damaged, we can price it like any other coin of its date and metal, and you can sell it or take it home. There is no charge for the look and no obligation to sell, and you leave knowing what you have.
