The seller ended that auction early (fee-bay should not allow this). Tens of thousands WSOP chips are produced and readily available, just buy into a tournament. Drop chips like the Trop, Luxor, MGM, and Arizona Charlies are made in limited quantities and those poker rooms have a no sale policy, even going so far as to threaten dealers with termination if they sell one. It is not insane, its simple supply vs. demand.
