Bubble Quarter

[uc6446]

Does anyone know anything about US Mint defects, and has anyone ever seen a Quarter like this?
It has a bubble on the face and the backside. They don't line up the are off by about a quarter inch.

Hmm I would guess that's post mint damage, but I'm no expert. Definitely cool looking!

Got tumors, probably from being underwater...P,M.D

Nope it's been in a fire. I have found several around old fire pits. I had one that was so bulged out it looked like a tiny UFO.

That makes sense, thanks.

I have found several of these. In quarters and dimes. They were not in a fire. It is environmental damage due to water. The zinc in the coin is causing the damage.

Fire coins can be fun. Found a penny the other day that was 10-15% larger. When it popped our covered in dirt, I though maybe cool token or odd coin. Cleaned off dirt to see it was just a zinc penny, only much bigger due to heat
