I'm no expert but I have sold around 3000 old crankbaits. Condition is everything. Lures that show a lot of wear won't bring nearly as much as the ones in new condition.
ebay is another place to search. Try to find lures with an active auction. Buy it now format doesn't really help me much. Those prices will be all over the place. I have taken to giving many lures away to the younger generation. I get a lot of satisfaction watching the kids catch fish on them. Alan
