I've seen nickels and cents from Canada, but what about quarters? While in Ohio, I got a crapload of CA money back in change along with a 1993 quarter. Anyone? Anyone? Bueller? Bueller?
Nickel is only slightly magnetic. Candian coins of the dates you specify are STORNGLY magnetic causing me to believe that they are not .999 nickel but steel. I have some verified pure nickel that I compared this to.
I can find no reliable source that gives the composition of Canadian coins including the Canadian Mint. If a magnet sticks to it, it's most likely steel.
