If you click on the "number of bids" link in each auction (even though zeros, now), it shows the reasons for bid changes. A few bidders, with high bids, did retract their bids, using a reason as "entered wrong amount". BUT, most of the bids were cancelled by the Seller, not the bidders.

I don't know who the Seller is. He/she may have gotten word about the new find, and being very ethical, cancelled these auctions so no buyers would feel they got "burned". If so, kudos to the Seller!!
