I'm Canadian so I can't help you with that question.
I do collect copper but as copper 1 Cent pennies that are 1996 and earlier date. the Canadian 1 Cent has been demonetized since 2014. They are worth almost 3 cents in US or, slightly over 4 cents CAD just for the copper. I have almost 10 pounds of them and may be useful as change once again.
