Other than the public reporting, how is that transaction different than a buyer negotiating and purchasing the item from a dealer at a show? There is an independent buyer and seller who have agreed to a price. Does that not establish a market price? Why do we need a third party (the underbidder) to establish a market?
How do you tell the difference when looking at past sales for comps? You can't which is why shill bidding increases the supposed market value of a card.
