I'm kind of new at this I noticed that they're looking for a penny small date 1982 at 3.1 grams I found this one looks different and it it weighs in at 3.0 grams
You have a 1982 large date copper cent. Because it is worn and corroded it weighs .30 a new copper cent weighs .31. Worth 1 cent or 2 cents for scrap.
There's only 1 1982-D small date copper, if you want to look through billions of coins for another one, OK. But so far a 2nd one has not been discovered. There are more 1983 off metal coins (copper that are supposed to be zinc) than the 1982-D small date. Your coin is from Philadelphia.
