What ACTUALLY happened as opposed to idle speculation about the prices they sold for and why.
The 3 jetons only had 3 bidders (4 on 2 of them but I dropped out as I knew that 2 others wanted them more than me and, although I was the first bidder, I thought it was the decent thing to do) and the reason the prices went up had nothing to do with the edge. I was speaking to the underbidder as the auctions were ending and the prices went up as they weren't bidding enough hence the higher prices (in order) of £147, £180 and £230. That's why the pink one went for more, no other reason.
Just thought I'd clear that up for anything who thinks anything else (not that anybody cares).
