Is this a nother stamped coin I've never seen one made like this one I have some but there your normal stamp coin. The liberty bell and the united States of America on one side the Bell on the other side found it in a roll of wheat pennies. But I've not seen this one around it's a new one own me.
Counter stamp.. Done way after it left the US Mint. Not a Mint Error of any kind. Just a damaged Cent. It does not matter if it is a N or a Z.
You guys crack me up I done know paddy man it don't have no value stamped coins are not errors but some times they are cool but yeah you're right it don't matter what it is just never Saw this stamped coins I done a lot of reading about them like I said I've done a lot of reading I knew it was not worth probably the penny but I might be able to slide it back in cirlation I don't like it anyway it's ugly.
The correct term is counter stamped. They do have value. Yours is on a 1996 coin so the value will be low and the coin has a spot of zinc rot which doesn’t help. Counter stamps on older coins can get expensive. Some of them are very rare.
