Well, I'll be the contrarian and say they are indeed worth saving and collecting. Whenever the Mint changes a design, the possibility of errors and varieties are increased. These coins are worth a hefty premium especially in mint state. Who wouldn't want to find out that they saved a roll of Speared Bison nickels in mint state inadvertently? Even if no unique varieties or errors are found in your cache, in mint state they are still collectible. It is up to you to market them to the seller. Offering them individually won't garner any premium over face, but if you package them as the complete series, you can expect a positive return on your initial speculative investment. Will you get rich? Not likely, unless you do have that roll of Speared Bison.
