You might be better off listing them on Ebay in small lots of a few figures each. I sold a bunch of loose Vintage ones years ago and I did them in lots of 3 or 4 that all went together in some way - core characters, by location (Hoth/Endor/Tatooine/Bespin, etc), by affiliation (Rebel/Empire/Cantina/Jabba, etc.). In other cases, I listed a vehicle with 1 or 2 figures that went with it.

Another tactic is to put two "peg warmers" - lesser demand figures - with 1 "valuable" one. Then people are forced to take the cheap stuff in order to get the important one.
