I have never seen clad coinage corrode to the point of just being basically the copper layer... Any speculation as to what type of environmental conditions would cause this?

It was most likely caused by some type of acid

For comparison purposes, these are the quarters from the side, next to a normal quarter

I can't imagine how a cashier would react to trying to spend these! I think I made out a 1967 on one of them?

If only acid could cause that, then that is a bit terrifying as these were metal detected not far from where I live... Can only imagine what is in the soil that could do that do a coin...

I would put wrap them with the rest of your coins, they're legal tender after all, so that means you only need 38 normal quarters instead of 40!

Yeah, that's the sort of "even all around" wear one expects from acid. Since the wear is quite even, the devices remain even though the coin is too flat for them to remain if it were circulation wear.

I have a colonial copper that looks like those quarters, but the colonial is only 200 years older. These coins deserve a WOW.

Creepy, but interesting. If coins could become zombie, this is how I would expect them to appear.

I have some dimes like these that I am about to throw back in the wild. Could be acid, Could also be medal detecting finds from a harsh environment.

Acid or ED. May have been buried in contaminated soil.
Rest in Peace

Don't suppose you were metal detecting in Love Canal, NY? It would make perfect sense!
