Yeah this happens all the time in Western NY. I remember growing up hating getting Canadian quarters because they wouldn't work in U.S. vending machines.
Not sure if this is still the case, but when I was a kid I loved getting the occasional Canadian quarter because it would respond to my magnets (where as US coins wouldn't).
So what Canadian quarters lack in currency value, they make up for in entertainment value.
I used to love Canadian quarters because they kept their steel/silver color all the way around, unlike the hideous copper-sandwich US coins. Was disappointed to learn as a kid that the Canadian coins were worth about 20% less than the American ones!
Just a couple years ago they were worth 10% more. Then oil tanked.
They're plated steel now, but they used to be five-nines nickel when we originally left coin silver behind.
