This looks to me like a Ring in operation, Maybe four or more people bidding against each other with the full knowledge of whats going on. Usually its a move to inflate the value of something or to prove some provenance. They probably have three or four of Moore's first LP's.Look at who is bidding. They most ly have one item in the record and one person with 20 successful auctions in his file is ahead now.
Is my skepticism showing???
