a few months back i found this penny in a coin star drop slot, like where the rejects go. My guess was that it went into a commercial clothes dryer, my father ( who has collected coins for his whole life ) thinks otherwise. i am 99% sure that it is PMD, but i wanted to double check with the community.
Hard to tell much of anything but it looks like a dryer coin to me. (Search the threads for "dryer coin" for an explanation.)
