For some reason I seem to find dimes with issues. I'm pretty sure this is some sort of error. Reverse and obverse pics below. In the same spot on both sides the rim appears to be doubled. If you look at the coin from the side it is noticeably thicker on one end of coin. Anyone know if this is an error and if it adds any value?
Looks like it was struck w/ a minor misaligned die. Some M.A.D. errors can command significant premiums, but unfortunately, I don't believe yours would. -Brian
