I save bronze pre-1982 cents, post-1982 Zincolns (because Zincolns are still worth more than face value) and I save all U.S. nickels for their copper/nickel content. When me and my mother go to 7 Eleven, I always ask the clerk for two nickels back in change, instead of one dime, when my mom buys a slurpee for $1.90. I think that the nickels are almost more worth it then the copper cents, seeing as you have to sort pre and post-1982s, while, with the nickel, you know you are always getting the same metals (unless you stumble across silver
War Nickels) I also ask my 7 Eleven clerk friend, to hoard all Canadian cents, regardless of what they are made of, since Canada quit making cents, pre-2000 copper/ nickel, and pre 1986 nickel nickels, and pre-2000 nickel dimes, quarters, and if he ever happens to get any, pre-2000 nickel halves, and pre-2012 loonies and toonies if for some reason, he gets them.
Speaking of copper coins though, does anyone here think people will start hoarding the current coins if the government decides to either, eliminate cents, or make them out of steel, and make the nickel, dime and quarter, and possibly the half and dollar coins out of cheaper metals? (I sometimes see mentions in articles about changing the metals in the half to a cheaper metal, but mostly they just mention the cent, nickel, dime and quarter, and sometimes they mention the end of the cent, and I have never really read anything that I can remember about them changing the metals in the dollar coins)
If they do change our U.S. coins to plated steel, I plan to start hoarding all copper clad coins I come across in circulation. (I wonder if history will repeat itself with the half, if the change the cent, nickel, dime and quarter ti a cheaper metal composition, and leave the same, more expensive metals in the half)
