Ways to Bid
There are two types of auctions available for bidding, Live and Timed.
- Live auctions are real time sales that allow you to watch the auction in progress and participate during the sale. The date and time you see listed for Live sales are the time the auction begins. You can place an absentee bid on a lot in a live sale, up until the time that lot is opened for live bidding. If you are the highest absentee bidder, our system will place your bids automatically, one increment higher than the last in-room bid, until we have reached your maximum bid.
- Timed auctions are internet-only auctions that are run for a set duration and available for absentee bidding only. These auctions allow you to place bids until the scheduled end time for a particular lot. Whoever has the highest bid when the time runs out wins the lot. The date and time you see listed for Timed auctions are the time that bidding on the first lot ends.
