Answer 2

There are only centennial Canadian quarters, not bicentennial ones, because Canada was established in 1867 and won't be 200 years old for quite some time.

Canada changed the composition of its coins several times due to increases in the price of silver. Some centennial quarters were minted in the older alloy of 80% silver, 20% copper, but in mid-year the composition was changed to a 50-50 balance. The best way to tell them apart is by weight: an unworn 80%-silver quarter weighs 5.83 gm while a 50%-silver coin weighs 5.05 gm.
