Wow a power tool and wire brush on a copper cent? IDK how you'd get that wavy look. Would love to see you're example in comparison. Heat or a chemical application would be more plausible then a power tool and wire brush. Nothing I've heard thus far fully satisfies my curiosity about this odd ball coin. IDK maybe chemical application with a wire brush then heat applied? lol

These coins get called heat. I don't think so. As you said, it would take a lot of experience with a torch to heat up just the inside to the point of melting and not harm the outer surface. In fact I've ran a torch from the 7th grade till my retirement, and I don't think it can be done. But what I think they are are sandblasted with glass beads. Sand would leave the surface sharp, but beads would leave the surface smooth and wavy.

This is a terrible phone camera pic. (it'll be a week before I'm near my camera setup) . This showes the waves created by a motor driven wire brush on a copper cent. Different hardness of wire should created different waves. A telling factor is how the brush skips over the high points of the design and forms the shape of the design as it drops down to meet the field.

Don't recall seeing a working die altered in this fashion. I'm thinking the coin was altered after strike. Thanks, Doug.

Lol sorry. The craft website is a DIY that involves torching a Penny. Someone mentioned it was a torch burn. And who wouldn't want to know how to make penny jewelry? Lol you're welcome.

Yes I would say my curiosity is satisfied, thanks everyone. Just got to say; Why on Gods green earth would someone do that to honest Abe? It's disgusting to this old man.

Just as an update I've found a few more strikingly similar to this one in three tubes I examined yesterday. Also found some possible grease struck through examples. I post pictures later. Wife has me working on the house today.

stoneman227 please let us know when you're "camera set-up" can display better pics. While you're pics resembles this coin I'm still not ready to toss this in a cull pile. If you can produce these characteristics in a pre-1982 cent with a mechanical wire brush I'd love to see pics.
