i'm thinking it was dipped in some type of acid
That's what I'm thinking too. What it was dipped in is a mystery. Maybe someone will know.i'm thinking it was dipped in some type of acid
I knew someone would know! Good job.Being in salt water for years does that and eats the copper out of the edges like that too. Looks like a detector found it, tumbled it, and spent it.

Mister Wizards!! Please post the results!
Here is an idea, someone glued it to the top of their car battery to act as a sacrificial metal, The quarter corrodes before the battery cables and thus the cables are not eaten away. You can do it with old copper pennies or clad which is zinc
Interesting... I was wondering if maybe it had been in a fire.. then into an acidic environment..
Yeah, we've seen a couple on the forums with the inner layer eaten away due to salt water or some other kind of corrosive. This one really got it bad with the face all cracked up like that. I wouldn't even try to spend that one.
But why the black stuff in between the layers of this matal..like black glue..doesnt seem to be a metal esp. Being black
