The minimum price a seller will accept for an item at auction. If bidding does not reach the reserve, the lot 'passes' — it does not sell. Reserve prices are confidential (not disclosed to bidders). The opposite is a no-reserve or absolute auction.
How It Works in Practice
Reserves protect sellers but create a trade-off: lots with reserves attract fewer bidders because the outcome is uncertain (the item may not sell even if they bid). Most estate auctioneers prefer no-reserve sales for general household goods and only set reserves on the top high-value items. When using reserves, set them at 50–70% of estimated value — high enough to protect against a bad day, low enough to allow competitive bidding. The reserve should never equal the estimated value.
