Hello and welcome to cointalk. It is a bit hard to tell from your picture but it looks like your penny was struck twice from the mint and is definitely worth hanging onto. If possible try and get better pictures of it or scans of the front and back if possible and we will be able to help you better. Nice find though! J
Yeah sorry - it does look like a hammer job and not double striking. Letters are going the wrong way. Just a damaged coin.
Thanks for showing the back. That indicates that it is a hammer or squeeze job and not a mint error. (The fact that the letters are incuse and reversed on the obverse is NOT enough to prove a squeeze job. ) The obverse COULD look like that if it was struck between a freshly capped die and a blank planchet in the coining chamber, assuming the obverse was the anvil die. (hence my request for a picture of the reverse) But to have incuse and reverse lettering on both sides it would have to be caught between TWO struck coins Something that would not happen in the press.
This image shows what happened. Your image and they the lower half reversed. Note how the letters on AMERICA is normal and all others are reversed. Definitely an alteration of a normal coin. Besides this coin would never fit into a roll.
