I think I have ruled out a few things. I don't think it was exposed to high heat because quarters exposed to high heat seem to have a more smooth bubble. The copper interior melts at around 2000 and the nickel at around 2600. But in this coin I think some of the copper is exposed. The nickel exterior couldn't melt and bead up (not bubble) without the copper interior melting. And there are absolutely no bubbled areas where pressure from inside have made a dome in the plating. I also don't think its solder (something I saw on error-ref) because of the accuracy of the raised parts on letters and features. The coin weighs 5.59 grams 86.4 grains The D is about 2.06 mm thick. Any info/rarity/value would be great, along with any references to anything similar. Thank you! Report this Post to the Staff

Crazyb0 Rest in Peace 10197 Posts	Posted 04/09/2017 9:02 pm That is a clad quarter that has been exposed to extreme heat, intentional or not. Heat causes the copper core to melt quicker than the cupronickel coating. This causes pockets of gas and "bubbling as seen. I would venture a torch, flame on obverse only, coin laying on concrete.

All the heated quarters I have found have smooth mounds 10x larger that look to me nothing like this. Edited by slow_livin_fast_time 04/09/2017 10:47 pm Report this Post to the Staff

They will all look different. Yours definitely looks like it was exposed to high heat. Not just the bubbles but the coloring as well, especially in the first pic you just posted.
