Copper slugs?

[theshoenlebens]

These spit out when I dumped my coins in the bank counter today. Are they slugs someone put in quarter rolls or what?
They are 1 inch dia. and approx. 1\32 thick and appear to be copper.

They look like planchets--preborn pennies--except they'd be 3/4" in diameter. Grade 1 planchets don't yet have the rim; Grade 2 planchets have been through the process that creates the rims.

If they're a true 1", I have no idea what they are.

foreign? what countries have 1 inch copper?

Yup, they are 1 inch and yup, they have a rim. It was funny how it came about. Just started dumping in nickels and out flies these three slugs and a Canadian nickel. This is unusual in itself because this machine never spits out the rejects. It throws them on the inside of the machine where you can't recover anything
So I just picked them up and brought them home and hoped you guys will know.

Maybe planchets for some sort of transit, parking, or gaming tokens?

Here are the "things" I'm wondering about.
