1982-D Small date - maybe copper?
First off, I'm not expecting this to be copper. I know there are only two that have ever been found out of billions. I don't have a coin scale, but I'm hoping to get one soon. The only reason I bothered to ask the forum about this one is that I did the sound test and it sounded almost identical to the copper penny. However, I know the sound isn't exactly reliable. Figured some more experienced people could tell me if it's copper or zinc if there are visible markers. Thanks.
