Canadian dollar, half-dollar, quarter and dime coins minted after 1919 and before 1967 contained 80-percent silver. Those minted 1919 or earlier are sterling (92.5%) silver. For these coins (1920 - 1966), every CAD$1.00 in face value contains of silver. The 1967 quarter and dime were minted in either 80% or 50% silver. The 50% quarters and dimes continued part way through 1968 until the mint introduced the 100-percent nickel versions of all the coins mentioned beforehand. To tell the 1968 nickel and silver coins apart, the ones made from nickel are magnetic whereas the silver coins are not.
