I think it depends. Are these proof sets of coins that were actually circulated? Those might be worth something though it would obviously depend on which ones. As an example, if you have a proof set of the 1935 Canadian penny, nickel, dime, quarter, 50c and silver dollar then you've got something worth a great deal. If you have a set of the coins issued for the 1976 Montreal Olympics, then you've got some silver trinkets but that's it. To me at least, this is a key dividing line: the coins of highest interest were those that were actually used to buy things. Though ironically, the ones that are most valuable now are those that were never used to buy things and are therefore in mint state!
If I were you, I would find a reputable dealer or appraiser and show the whole mess to them.
