Does anyone know anything about coins. I found this coin in an attic while working today. It is a penny, and I think it may be a mint error. It looks like it has 2 Lincoln heads, it says liberty twice (once directly across from the other, and written backwards), you can make out the word trust, but it is backwards and on the wrong side, and it has two dates, 1983 and 1994 written backwards. It also looks like it is slightly off center and the bottom part is smashed. You can make out a little bit of the back, but it is hard to see. Anyone have any ideas what causes this? I have pictures, but it wouldn't let me upload them.
