1972 D Ike. Mint error? Post Tomfoolery

Post by Badactor67 » Fri Sep 27, 2013 5:13 pm

Basics on this coin:
1. I call it a "copper sandwich" its the only thing that comes to mind.
2. The thin silver layer is separated from the copper layer by about a 1/8 inch deep gap it is so uniform that it would appear to NOT be done by some amatuer looking to accomplish something.
3. Both sides are reeded the silver side is reeded like a dime, the copper side like an Ike.
4. This was pulled from a bank vault.
5. If it was doctored the only thing I can come up with is it was used as a "cheat" for slot machines. However that does not explain the reeding difference. That is only a theory.
6. The coin is perfectly centered on both sides.
7. The "meat" of the sandwich appears to be copper.

Theories so far:
It was a cheat coin? I could see a sting fitting perfectly into the groove. But again why the different edge?
It was some kind of mint "mock up" for design? Some kind of "just make it work" type thing..

Just an ODD find.

Any thoughts?

It is heavily "hazed" I have not touched it in terms of conservation.

TIA !

other denominations have the same error. A dime has it, not 100% what it is.

i have been trying to find the thread (probably another site) where someone attributed this to a chemical/acid treatment that ate away the copper core, but left the outer layer more intact. Their claim was the copper would be eaten faster than the clad outer layers, resulting in the "sandwich."
I am no master of metallurgy, so this could be way off base, but I do believe some other sites have found simalar coins in the Kennedy Half series. That being said, my vote is that this is indeed tomfoolery, aka PMD.

I wonder if it could been a source metal for a small copper electroplating project?
