Guys, there's a difference between a "silver" weapon (a weapon made out of pure silver) and a "silvered" weapon (a weapon the incorporates enough silver to make it damaging to weres and other beasts with low damage reduction).
Yes, pure silver makes a lousy weapon. But be reasonable - they wouldn't include "silver" damage reduction if the only way to get it by core rules would make the weapon unuseable. Silvered weapons either are an alloy, or have a form of silver coating, or somesuch. They're harder and more costly to make than normal, but should still be viable weapons (and should cost significantly less than a +1 magic weapon).
