Hi guys, I have this 2002 P Indiana State Quarter and would like to know if this is an Improperly Annealed Planchet? For comparison I have shown the 2 state quarters side by side. The quarter I am referring to is on the left side. I looked at the edge of the quarter and see that the copper part of the edge starts to transition to a really dark brown color. (rim photo quarter is on left side) Is this an indication of an improperly annealed coin?
In my opinion, their just toned differently . Here is a link for the Error in Question .Improper Annealing (error-ref.com)
The normal consideration is that an edge would be normal if improperly annealed. An improperly annealed coin would not affect an edge. IMO, so just discoloration . Jim
Appears to just be environmental toning differences to me. @paddyman98 has shared some of his improperly annealed coins before and there is a more obvious color difference between coins. JMHO
