I found these with a group of coins I bought last summer. I have no idea on value and would like to sell them since I don't collect Canadian. I also have a bunch of halves, quarters, dimes and 5 cent silvers I wanna move too.
They are all common coins. If you were to try to sell them, you wouldn't get much more than $10-15 Canadian for the whole lot ($8-12 US). Those years all had large mintages and yours lack any easily identifiable varieties.
