1980 Copper Dime???


New member
Found this metal detecting in a backyard - any ideas what this is??? Looks like a penny but it's a dime.

Note: There are some scratches which is what the shiny parts are in the pictures.

Thats the stuff you have to get of the surface before the banks will take them, numerous recipes for cleaning on here. Sometimes CoinStar will let them pass through.

will anything remove that copper coating?
I clean my clad in a rock tumbler with a mixture of a handful of pea gravel, 1/4th cup of white vinegar and 2 tablespoons of salt. Tumble a good handful of coins for about 1 1/2 hours, depending on how bad they are. Don't clean cents with dimes, nickels and quarters. And for cents I use the above with the exception of using apple cider vinegar rather then white. Good luck. HH jim tn

1/4 cup white vinegar, 10 squirts of Gojo or Orange type pumice hand soap. Just enough water to cover coins. Can fill tumbler about 40 percent full, or my Lortone wont tumble due to weight. Two hours or so, they come out steel gray, decent. As mentioned do pennies separate, or you will make brown quarters. Never tumble a collectible coin.

If you can find one 1964 or older they were silver back then and they come out of the ground nice and shiny.
Not all of them! I had some that I didn't know were silver until I tumbled them. Be careful to keep from tumbling pennies with dimes and quarters; pennies discolor them pink. You don't need to ask how I know. Also if tumbling corroded zinc pennies, white vinegar will react and bulge the container with too much pressure.
