I always get a bunch of coin tips at work, and I've noticed some coins that don't quite look the same as others. So I decided to start collecting weird coins, I'm sure this one is worth about .01¢. I think it looks cool nonetheless. I'm a beginner to this and I was curious what could make this happen to a penny? Any ideas? I tried looking for another coin similar but I can't seem to find what this would be considered? Or if it's just damaged? Thanks beforehand for any answers!
