Hi,
I'm new to collecting so forgive me if this is something common or mundane.
I was looking through some 1982P small dates, and noticed the reverse has some raised lines running through the "I" of both "United" and "America".
Is this an error, and if so, what type of error is it?
Please note that this is a copper cent, not zinc.
Also, I apologize for the poor pictures. I'm still experimenting with lighting.
