Still no explanation for the upper area. I did take a plastic flossing pick & semi lifted the bottom edge. It's clean lookng copper color with green corrosion. (Not bad at all) on both sides of the piece. After 34 years I'd expect it be rotted to oblivion if that were zinc rot. We've all seen it lol

Good find! It's exactly what Mike Diamond said it is.

Definitely a keeper, I'd love to find one like that.
Keep in a 2 x 2 for sure or even an air tight container to keep the corrosion away.

A couple of cuts with a razor blade and leave in the wild for a time and you can make one yourself. PSD. |

Okay then so it is not a struck through? This is its own copper coating lifting up?

Correct. If it was a struck through foil, the zinc would still be covered. Its not, so that is the normal copper plating coming off the coin.

Oh. So the Copper plating is coming off, from someone prying it off with a sharp tool?

I can't explain the top. Picture 1 & 4 clearly shows there is copper under said foil. No exposed zinc. If I rip off the bottom piece, its clean matte looking copper. & the 4 & detail below goes with it. I lifted it & looked carefully. Remember the channel you see is not indented. Both the top & bottom overlap what appears to be a cut.

Just going by what I saw. I'll take your word for it.

It's possible some of the plating started cracking before the coin even emerged from the plating bath. In that way, you could have plating deposited over an exposed area of zinc core. That's the only explanation I can come up with for your observation. I see no evidence of human interference in the formation of any of these cracks.

This makes great sense.. Not only would that allow the mentioned Cu plating over zinc to occur but would also allow thickening of the lift.. There's no way a typical plating thickness of copper would still be holding solid and hanging around after all this time; it would have peeled / lifted off and/or broken away in pieces and bits long ago..
