Please excuse my first new to this. I tried to upload pics of my coin but haven't figured out how to get the pic to display. What I have is a 1979 d penny missing the o in the word of on back of coin. It appears that the stamp didn't completely set into the coin. The f is also missing part of its form. Has anyone ever seen anything like this. Will post pics as soon as someone can help me get them on here.thanks in advance
