It is a fascinating thing to compare the prices things fetch on ebay with what a similar piece will fetch at an auction house auction with bidders on the floor .
So far in my experience ebay auctions can often be the better value plus there is no "Buyer's Premium"

to tack another 15-20% on to the high bid price .
I often wonder if it is the heat of the moment on the auction floor that drives pieces to such heights whereas bidding on ebay is a solitary detached kind of experience .
I definitely would not have bid the price those fetched (unless I had a nice big chunk of ivory or two to send to Battara

)
