Since no conditions/restrictions are placed on the bidding, then
the bidding is conducted as a "normal" auction. The auction ends
when no one wishes to bid higher, just as a normal auction.
The Methuselah who played the card should conduct the auction
and use some form of "going once ... going twice ... fair warning
and sold" method of closure.
