A passed lot is a lot that didn’t sell at auction — either no one bid on it, or bidding didn’t reach the reserve. The auctioneer “passes” the lot and moves to the next one without dropping the hammer.
Passed lots can sometimes be sold post-auction at a “second-chance” price negotiated with the highest under-reserve bidder, or they revert to the consignor unsold. High passing rates indicate weak buyer demand, aggressive reserves, or both. Auction houses track “sell-through rate” (the percentage of lots that sold) as a key performance metric — consistent rates of 80%+ indicate healthy auctions.
Passed lots have a second life. Many auction houses run a “post-sale” window where unsold lots are offered to underbidders at the reserve or a negotiated price. Some lots are returned to the consignor and re-cataloged for the next sale at a lower estimate. Some are pulled from the auction circuit entirely and listed with private dealers. From the consignor’s perspective, repeated passing is expensive: storage fees, photography fees, and re-cataloging fees add up. Reserves that are realistic for the current market reduce passing and improve net proceeds.
