70+ year old coins

It always amazes me somewhat when I find coins this old still floating around in circulation.  Kind of makes me wonder what things will be like in another 70 years.  I'm betting the nickel won't be around...

7 rolls of nickels

1939-S (I just need three more to complete the set)

14 rolls of pennies

1951
1976 Canada 1 Cent
104 pre-1982 coppers
