Sweet, I pulled out a 1952 dime out of a coinstar on Thanksgiving 2018. Every once in a while you'll find something nice in them.
My find a couple weeks ago included a Canadian Dollar and a Canadian 2 Dollar, a New Hampshire toll token (stopped using them about 8 years ago, probably more), a Penny of unknown origin that has Queen Elizabeth 2 on it, a couple of dimes, a nickel, and about 20 US cents. P.S. - there is a thread dedicated to Coinstar finds. https://www.cointalk.com/threads/reject-tube-coinstar-finds.201092/
The QE II penny is British. Just like on their postage stamps, Britain doesn't put the name of the country of origin on their coins. They were the first to issue postage stamps as we know them today, so I guess they didn't see the need to put their country name on them.
