do you pick up Canadian coppers while you still can? Heck, if you can get *any* Canadian pennies the value is already well over face!
Actually I do, I have a massive amount of them at the moment. Have been taking them out of circulation for a long time now. They are incredibly easy to find since they kept making them until the late 1990's here. They will be completely going out of circulation soon though as Canada is getting rid of the penny and going to 5 cents as our lowest denomination.
Nice. Even wrote two articles on it:

and

I think it's important that the people keep the value in these coins rather than hand them back to the government. Glad you have a stash!
