It's apparent now that some folks could disagree that the sky is blue, insult those who believe it is, and then claim first hand knowledge of the creation of the universe as proof. If you're still expecting to find great bargains on eBay you'll be sadly disappointed. In the old days at farm auctions, one could occasionally buy Red Wing for pennies on the dollar. In that setting, a shill bidder could really cost you some money if you were the only legitimate buyer.
Collectors drive the market here.
No need for a shill bid in this situation. Rusty seems to think things work in some mysterious way on eBay such that we're continually suckered, but offers no evidence. I'd love to hear it if it exists.
