Canadian coins often filter down to the states; So, I have tube filled with Canadian pennies as well.

I like that Canada added a dodecagonal frame to the design so that it is easier to separate the copper from the copper coated pennies.

Half of the 1982 pennies in the US are copper. The other half is copper coated zinc. One has to weigh each penny to keep the designs separate.

BTW, the coin the US nickel is the coin to collect today. It's melt value is worth more than a nickel.
