Copper dime would be a Dime struck on what pennies are supposed to be struck on. If it's dated after 1982 it'd only be 2% copper and 98% Zinc. I'd think that you should be able to get any where between $15.00 to $50.00. The YEAR and MINT is probably going to be all the difference between what you can expect to get. Your best option would be to sell it on Ebay. These are pretty rare but I can't tell you other than put a reserve amount, because it might be worth more to you, than someone who stumbles across your Auction. There should be a good bit of an edge around it due to the dime being smaller than a penny.
I really don't have any idea Greenville Coins
