I don't know what to do!
I have found a 1999 "D" penny. Upon careful observation, I've noticed that the thickness of the penny was not even. I say one side of the penny is about 35 thinner than the other side and does not have the usual rim that goes around the coin (meaning the surface of the coin is even all the way to the edge). My question is, is it worth something? Worth grading? What is the rariety factor?
