Wasn't there a period from mid-60's until ? during which Canadian higher denomination coins were (non-magnetic) nickel alloy? This webpage helps answer, and it looks like instead of the USA nickel alloy composition (25% Ni, 75% Cu) the Canadian mint used nearly pure nickel from 1968-1999 for dimes, quarters, and halves. Pure nickel is ferromagnetic so presumably these are attracted to a magnet also, besides those minted 2000 and onward which are primarily steel (boo!). I may have found some Canadian dimes in those 99.9% nickel composition years -- I'll see if I can find them and check with a magnet. Or maybe one of you would... Update: just checked a 1975 Canadian dime with a magnet. Yep, they attract! So although that won't tell you if it's iron (2000-present) or nickel (1968-1999), it should in most cases (I don't think 1982-1999 5 cent pieces which were same alloy as US 5 cent pieces) tell silver from non-silver. All the valuable stuff I learn here everyday.... Link to comment Share on other sites More sharing options...
kac Posted July 3, 2020 Share Posted July 3, 2020 Pure nickel or near pure nickel will stick to a magnet like the tiny denmark coin which is probably similar to the transitional Canadian coins. Odd how once alloyed, nickels turn to trash in the ground. Link to comment Share on other sites More sharing options...
