Looks to me like it has been in a rusty tool box.

I'm in the paint/stain camp, but I've been wrong many times. If you ever had a bulk TPG submission, you could send it in for grins. |

Does acetone remove paint? Try that - won't harm the coins then

An overnight soak in acetone did not affect the copper area, which seems to be flaking along the edges of the coin. The coppery area is impervious to acetone. |

Maybe a science experiment? I mean the reverse is almost exactly half the coin is colored. maybe it was dipped?

Certainly possible, although how do you dip half of one face and not the other?

Somebody tried an electroplating electrolysis experiment.

What I have against it being an annealing issue is there isn't a smooth transition from copper to silver color. There is no way heat would travel as ragged as that edge line appears. Could be a thin plating.

Brandmeister, you could email Mike Diamond to see what he thinks.

How about an overnight soak in distilled water?

By looking at the pics it almost looks copper plated. With the plating failing.
