    found this one in change, the pic is admittedly terrible. But it is obvious seeing it that the left hand rim is thicker than the right hand side, it forms almost a crescent shape of a ridge that extends farther from where the rim should be, the right hand side is normal, and the reverse is normal, the obverse looks like it is shifted up and to the left a bit, the "L" in liberty is messed up because it hangs over the edge of the thicker side as is the "in" in the motto, it is more dramatic than it looks in the pics, any ideas? Thought it was kind of interesting.

    It's a form of die deterioration that's almost exclusively associated with zinc cents.

    hmm thanks for the input, so even though the rest of the features are pretty sharp, and the rest of the lettering is sharp it would be a deteriorating die? What would cause it to make the thicker rim on one side? And what about a deteriorating die would cause the lettering in the motto to be right on the edge of the rim? Or is it a combo of things? I have collected coins for over 30 years, but I haven't ever gotten into errors except popular DD's overdates etc, so any other input would be appreciated as to how that can happen so I can better understand.

    I think the die might have been slightly slanted at the time the coin was struck. :whistle:

    The die undergoes deformation. The area just inside the die's rim gutter sinks in.

    OK here are some better pics, the consensus seems to be die deterioration, if that is the case why would the strike be fairly sharp as it appears to be? You can also see where the "in" in the motto is almost gone because it is on that ridge and the "L" in liberty is the same way. Please help me understand the details of how that works, if it is over polishing or worn out die wouldn't the details be weak or the motto spread out and flat? What would cause the thicker ridge on the left? Thanks!

    OK, thanks, if you don't mind I am trying to wrap my head around the mechanics of this, die deterioration usually occurs because of over polishing or simple wear right? Why would the rest of the strike look OK where the thicker ridge isn't? Or is it that only that side of the die is weak and didn't stamp far enough into the planchet? Thanks for the lesson.

    It's obvious peripheral die damage.

    There is absolutely no sign of damage to this die.
