    big lamination error. It almost looks like it was buried in the ground for a while. Where are all the metal detector hounds out there? @paddyman98 ?

    I don't think it is a mint generated Lamination Error. It seems to me that this type of peeling was caused by some kind of extreme environmental exposure .

    Well, I peeled the layer off and look what's left, not much to look at now. OBV.JPG REV.JPG

    I think it might have been paint or glue or something, whatever it was it wasn't good for it.

    It didn't have layers to start with.

    A corrosive agent or oxidizer reacted with the coin's surface, long and hard enough to go fairly deep. This reaction produced a layer of copper oxide, and that's what peeled off. At least, that's my bet.

    Cool, Did the layer that you took off crumble up into a sand like texture?

    Yeah, it turned to dust when I rubbed it between my fingers. It weighs only 2.7 grams now.

    Yeah, I think you're right.

    For what it's worth, I fiddled a bit baking cents with a giant Fresnel lens and sunlight. Zincolns wrinkle and spill their zinc core; at the peak of summer, one actually burst as the zinc interior boiled. But copper cents got exactly the kind of layer you show here, and it behaved exactly the same way.

    I haven't yet managed to melt cupronickel, and I don't think I've melted copper/bronze, but I've softened silver enough to warp a Roosie (which was already holed, and fated to suffer a grisly death in one experiment or another).

    Looks like some old added plating that eventually came off. PMD.
