A nickel is now worth over six cents and will probably soon be made out of zinc.  Right now they're 25% nickel and 75% copper.  Collecting nickels is a great way to save with no financial risk since a nickel will always be worth at least a nickel.  I've started to collect them, getting a few rolls every time I go to the bank.  I figure it's like making a 20% profit on every roll I buy.  The downside is figuring out where to keep them all.
