Quote:Yes, to be sure the surface is pitted, at least on the obverse left side. I wonder if this could be
PMD while the copper visible on surface is NOT a result of wear or
PMD, but rather mint error. Consider:
1. quarters which are much older and much more worn (to the extent that all text is illegible) don't even show this much copper on surface
2. on reverse the surface over "AMERICA" is copper tone, AND the edge of the coin closest to it is full copper, NOT a typical "sandwich" of copper-nickel/zinc
Wrong allegations..
1. The coin do not show Cu color.
2. "sandwich" is not a numismatic term. We say Clad
3. This coin has the environmental ferric oxides.
Hope will help you in the future to made distinction between Cu aging colors spectrum and environmental oxide.
