Hi guys, I have this 1941 D Lincoln Wheat Penny and would like to know what is going on with the top of the Reverse of this penny. There is a ridge on the upper part and the metal sinks down lower and is a different texture.
I thought delamination? but I'm not familiar with the strike-through error. I wouldn't know what to look for
It looks connected to a die crack that runs through "E" and under "P" of "E PLURIBUS", then runs under ON[E]. I'm guessing "No" on corrosion.
Not a lamination, imo. Photos are very dark, but as P & G says, this looks like corrosion or chemicals on the reverse.
My knee-jerk is a lam. But look at those letters. There's no way this is a lam, as a lam would have mangled those, some, and they're intact.
