I have a 1982(small date) coin with a strange error. Or what I believe to be an error. I'm curious to learn what is wrong with this coin. I believe it weighs like a normal penny for that year. Either the 2.5 or 3ish grams. Don't know which one exactly, I just remember it weighing normal. Not like the 1.4g or whatever they usually are. Any help is greatly appreciated! Thank you.
