Absentee bid

Also called: commission bid, book bid, left bid, maximum bid, proxy bid

An absentee bid is a bid left with the auction house before the sale, stating the most a bidder will pay for a lot, which the auction house or platform then executes on the bidder's behalf against the competition.

An absentee bid lets a bidder compete in a sale without being present, in the room or online, at the moment the lot is offered. The bidder tells the auction house the most they will pay. The auction house, or the platform, then bids on their behalf only as far as needed to beat the competition, up to that limit.

How an absentee bid is executed

The rule is one increment above the competition. Suppose a bidder leaves $1,000 on a lot that opens at $400 with increments of $50.

  • If nobody else bids, the lot is knocked down to the absentee bidder at the opening bid or the reserve, whichever is higher.
  • If the room reaches $600, the absentee bidder is taken to $650 and wins there.
  • If the room reaches $1,000, the absentee bidderโ€™s limit is matched, and because their bid was placed first, the auctioneer may knock it down to them at $1,000 or ask the room for $1,050.
  • If the room goes past $1,000, the absentee bidder loses.

In a live sale the clerk executes absentee bids from the book, or the platform does it automatically against room, phone and online bidders. In a timed sale the same logic runs as a maximum bid: the platform bids for every maximum bidder in turn, enforcing the increment table, until each lot has a winner or passes unsold.

Why absentee bids matter to the auction house

Absentee bids are the best signal an auction house has before a sale. A lot with three absentee bids above the low estimate will sell; a lot with none needs marketing or a word with the consignor about the reserve. A good auction house CRM records every absentee bid against the client, successful or not, because an underbidder on a rare coin is the first person to tell when a similar one comes in.

Phone bids are the other form of remote bidding, where a member of staff relays the bidding to the client live. Platforms that manage phone bidder cards and absentee bids in one console keep both from clashing during the sale.

Frequently asked questions

Will I pay my full absentee bid?

Only if the competition pushes the price that high. Absentee bids are executed one increment above the next highest bid, so a bidder who leaves $1,000 and faces a top competing bid of $600 wins at $650, not $1,000, assuming the reserve is met.

What is the difference between an absentee bid and a maximum bid online?

They are the same mechanism. Absentee or commission bid is the traditional term for a bid left with the auction house for a live sale; maximum bid or proxy bid is the online term. In both cases the platform bids for you, one increment at a time, up to your limit.

What happens when two absentee bids are the same amount?

The bid received first wins at that amount. Platforms record a timestamp on every bid for exactly this reason.

Can I leave an absentee bid below the low estimate?

Usually yes. The bid is only successful if it reaches the reserve, which may be below the low estimate. Many auction houses will tell you if a bid has no chance of succeeding.
