Canadian quarters and pennies showed up fairly regularly, and everyone tries to get rid of them in vending machines. Never saw pesos, and I lived 100km from MX.

Or any countries next to each other

I assume Canadian/USA coins and Mexican/USA coins turn up in each others places sometimes.

Apart from the usual NZ coins, I've gotten a Fijian 5c piece, a Malaysian 10 sen coin, and a Saudi coin I got no idea what it's worth. Same size as a 10c coin.

What foreign currency have you gotten as change from the shops in your countries by accident?

will be in NZ soon enough. I'll go with Kiwibucks for you.
