Personally, I'll take any "junk wax" cards you have. I build sets, and it often isn't the star cards that are hard to find - it's usually the "Joe Blow From Kokomo" common card that keeps the set from being complete.
When I first started collecting, there was no Internet to find the missing common card. If your local card shop didn't have one, you were pretty much out of luck.
So, please don't throw them away. I'll take 'em.
Trades are turned off for now.
