I have two 1971 no mint Mark quarters, both different from the other, you be the judge. (side note found both on the ground)
I think I see coin wrapper crimping machine damage on the left and circulation wear on the right? Not any kind of Mint Error
Two coins, with Two varying types of damage, whilst in circulation. I don't see any specific errors but then I'm just casually looking at it because nothing specific was pointed out.
What I see by looking at them is the thickness of the 9 and 7 on the one with the promeprom ring is thicker then the other. Caused by wear ? The B is thicker as well. I appreciate all whom have responded, and am now hooked on coin talk.
