Unless, of course you want to keep them and hope they'll have some premium in 50 years. After all, crisp sequential silver certs have more of a premium than if you sold them individually. To each his own, but I believe that modern FRNs (especially crisp uncirculated) will be worth something in the future (no one seems to care much about them unless they're a fancy serial)
Edit: On the other hand, forget everything I just said! (It's my secret strategy, the less surviving crisp specimens the better!)
