I have seen it so many times if you listen to the auctions very carefully you can even hear the conversations between the auctioneer and room bidders. Even if you bid 500 as your max he will say to the interested party" bid £500 and that will clear my commissions" (they don't like these bids too much hard work). It negates the who bid first rule because you will never know anyway. And he probably nudge nudge wink wink'd a deal . Most of them are there every auction. Old pals act. Internet bidders are a faceless entity . Far easier to get paid there and then than to email internet bidders with all the spiel . Just creates more of a paper trail. If proof is in the eating of the pudding the only two bids I left I lost with the exact same price as the winning bid. Every coin I bid on live and won . I won no problems. I will never leave bids again.
