It depends on what you have and if there's a crazy person out there to buy it.
If you have any of the round head, fine toothed, quick release, flex head ratchets, they fetch 4-5 times their original catalog price depending on age & condition.
Likewise, some of the Craftsman Professional series wrench sets, like the deep offset double boxed end wrenches get pricey on ebay. Look for the items you have in the completed auction search feature on Ebay to get a feel.
I don't think the regular plane jane U.S. Made craftsman stuff does that well though but, there are idiots that prove me wrong often
