Well my eyes may have decieved me but for $10 after shipping I think well worth the risk... The conservation process i use should clear the area around the date nicely... What date are you seeing
Looks like it could be a 2, 3, or 6. I guarantee there are large cent collectors who could pin it down by the position of the design showing. I may take a crack at it.
Please do take a crack at it if you feel like it... I did enough with the pics to make me think "57 small letters" is a good possibility... I also admit it fits well with the 56 images... either way at $10 a fun coin to play Doctor with lol...
