Looking for some help on this penny to determine if it is unique - It appears to be a rainbow penny with some sort of die error or ddr on reverse - It looks like a 1 above shield
Stained/discolored obverse Although the photo of the reverse isn't great, it appears to have a liquid or someone on the surface, plus lots of scratches. Everything you see as 'different' on it occurred after the coin was in circulation.......sorry
I've mentioned the following plenty of times.. Could be dried urine. When it dries it leaves rainbow tones. Always wash your hands after handling coins.
