Dave G"...considering some bidders consider the activity of other bidders into their considerations of the value of an item."
I think this statement is the key to the whole process......its not how much an item is really worth, it's who else is interested in it and why. Sadly in some major card auctions it clearly is not a truely knowledgable person bidding, but someone with money who will have it at all cost - especially if he doesn't want other specific people to have it.
