Coin dealers and collectors may be able to help you, too. Take a clear photo of both sides of the coin and send it to coin collector groups online when you can’t bring the coin in person.

Coins are graded on a 70-point scale where 0 is “Poor” and 70 is “Mint Condition. ” Coins rated “Good” or 6 are actually very worn, and ones rated “Fine” or 12-15 have a medium amount of wear.

Coins are listed at wholesale price. You may not get as much when you sell the individual coins.

You can also separate the coins based on how worn they are, the metal used in them, or where they were printed.

Many dealers can also handle rare coins, but you’ll usually get more money from auctions or private collectors when selling these coins. Remember that dealers are running a business. To make a profit, they’ll pay you less than the wholesale price. It’s best to let multiple dealers evaluate your coins. Stay polite as you continue to shop around.

Take good pictures of the coins to get more interest and fairer offers for your coins. Work in a well-lit environment so the lettering and mint marks are as visible as possible.

Whatever you do, avoid advertising in your local newspaper. Even if you meet someone in a safe place, this makes your coins a potential target for thieves.
