Can you help me? I really don't know how to find something remarkable on the coins, I have some 1982 not mintmark but it's seems there are son worth. what I have are copper 3.10, this is one of them. I know it's not 1982 d small date.
large date, you say copper? did you weight it? if copper it should be right around 3.11g. I see a lot of circulation hits and wear. Nothing really special though. Just a normal Philadelphia minted CENT
