What is this ErrorsOnCoins struck-thru?

Zoins

I was looking through @ErrorsOnCoins collection and ran across the following cool looking struck thru.

It doesn't say what it's struck thru. Anyone have any ideas?

Possibly a thick piece of fabric of some sort?

Looks like something thick, such as a piece of heavy card paper. Just a guess... Cheers, RickO

The edge of the strike thru is too sharp for grease.

The texture of the strike thru is too uniform for fabric.

The strike thru goes right up to the rim but not over it, so the material was malleable enough to expand under the force of the strike, but wasn't hard enough to deflect the collar.

My guess is that it was a piece of copper plating from another coin, or perhaps a piece of aluminum (are feeder fingers aluminum or steel?). It resembles coins I've seen that were struck through clad layers, though there's no reason for one of those to be near cent dies.

I agree that it's not schmutz. There are a lot of parallel lines visible in the struck through area that imply structure.
