Here is a coin for which I have no explanation. The reverse center is depressed, around which is a raised doughnut like shape then a depression between the doughnut and the rim. When I first found this coin I thought it was someones attempt at putting two coins together, but under 20 power magnification I could see no seam on the reeded edge nor could I see any seam inside of the rim. The obverse of the coin is prominently domed,however I have not been able to get a good picture to show this.

I think the coin was tampered with.

Im curious if it weighs as much as a quarter. If it does, then I'd guess, too, that it's either damaged or tampered with.

The rim and the edge of the rim has some characteristics of a Dryer Coin (or one that has been hammered/spooned just a bit), but the rest of the coin doesn't look like a Dryer Coin to me.

Does it sound hollow? Although I don't know what a hollow coin would sound like.




Rest in Peace

This is the effects of heat. The trapped gases between the layers expand causing the bulging.

I wondered if heat could do that.

What is a Dryer Coin? and if this is heat induced can this result be reproduced? If so how would it be done, I might like to experiment to see if it can be done. Thanks

a Dryer Coin is one that went through the laundry dryer. Go the whole nine yards, though; wash the coin first.

I Dryer Coin is a coin that lives in the fins of a commercial dryer for a while...if it lives in there long enough, the rims become flattened, and the coin looks thicker on edge.

Looks like one of those electromagnetically shrunken quarters, but the power setting was too low. The field started to crush the quarter but either the capacitors were not fully charged or the coil failed prematurely.
