The thing is, the Treasury is looking at new metal compositions for the nickel because the value of the coin itself is actually 7.2 cents, not 5 cents. At some point in the next few years, you'll see current nickels leaving circulation (Gresham's Law), very much like pre-1965 silver coins.
Am I hoping to make a lot of money this way? No. I suspect you will be able to buy bags of nickels at some point in the next 5-10 years at double or perhaps triple face value. Still, I can't see myself stockpiling a million nickels. Part of me just likes the thought of gaining instant value for my cash. The other part likes the idea of having a story to tell in 20 years why I've got bags of nickels in the basement.

Worst case scenario, nickels have an internal put option--the least they'll be worth is 5 cents.
