This penny seems to have a chunk missing behind Lincolns' eye...?? Also strange raised line up the reverse of the coin..? Any ideas?
The line on the reverse looks like a plating blister. I don't know what that is on the obverse. Your photo isn't clear enough. ~ Chris
Lincoln's eye is normal, maybe a bit more defined than others or it could be a small plating bubble that bursted open. The reverse is a plating blister. Nice one but not worth any extra. I'd keep it for educational purposes.
