That's..... Interesting.


I'd like to take this opportunity to address this, one of the many reasons WHY, and I think I've made my opinion known, that you guys don't be so quick to discount types and varieties based on bad pics coupled with what you might think you know to be fact....

Sorry for the side track. Carry on.

New to this as I am not a collector. I have however set aside coins that appear to be out of the ordinary. What types of non destructive testing are used to authenticate a coin like this? Any recomendations?

That's certainly a nice find! I'd send that to a TPG for authentication and grading.

Could it be a foreign planchet that was supposed to be minted for other country and accidentally minted this cent around that time period?

Video suggests stainless steel or nickel plated steel to me.

Both metal compositions harder than copper plated zinc; this suggests that if normal striking pressure was used, then the detail on the coin should appear if it has been lightly struck. Compare striking detail with normal 1987 Cent.

Alloy composition can be found with XRF analysis, but for surface only.
Take it to a bullion dealer or jewelry buyer; they should have a hand held instrument.

The problem is where would such a planchet come from? We stopped striking coins for other countries in 1984. On the other hand the cent planchet were from an outside supplier. It is possible they were also making planchets for some one else and one got mixed in with the planchets shipped to Philadelphia. It has been known to happen. Who it would be for I have no idea.

The Royal Australian Mint hasn't made it's own planchets for a long time, either.
