This page offers instructions for new bidders in our auctions. It explain the difference between bids placed prior to the auction and bids placed live during the auction. It also gives a complete list of the different bidding methods. If you are looking for the conditions of sale, they are available on a separate page:


Pre-bids are bids placed prior to the auction. They will be defended by the auctioneer during the live auction session against the room bidders, the live bidders and the phone bidders.

You are invited to enter your maximum bid. Your first bid will be at the reserve and will then be increased by the appropriate bid steps (see our conditions of sale) against the other bids until all other bids are surpassed, or your maximum bid become surpassed by another bid. The book bid has priority in the auction room in the case of a tied maximum bid. If the winning bid is tied by two book bids, then the priority is given to the bid we received earliest.

Pre-bids must be placed at least 3 hours before the live auction start. See the list below of the different options you have to place pre-bids:

Room bidders attend the auction in person, register and are attributed a paddle number. Then they can attend the auction room where they can place bids by raising their paddle number.
