What is a reserve price?
A reserve price is the confidential minimum a seller will accept for a lot at auction. If bidding never reaches it, the item does not have to sell. Here is how reserves work, when to use them, and how Unovance handles them.
A reserve price is the lowest amount a seller is willing to accept for an item at auction. It is set in advance, agreed between the auctioneer and the consignor, and kept confidential from bidders. Crucially, it is not the same as the starting bid: a lot may open low to attract attention while a higher reserve quietly protects the seller.
During the sale, bidders are usually shown only whether the lot has met reserve. If competitive bidding climbs above the reserve, the lot sells to the highest bidder. If it never gets there, the auctioneer buys the lot back (a pass) and the seller keeps the item, often opening the door to a negotiated post-auction sale with the leading bidder.
Example: a piece of equipment is listed with a $1,000 opening bid and a hidden $8,000 reserve. Bidding races to $7,500 but stalls. Because $7,500 is below the reserve, the hammer does not fall — the lot is passed, and the house may follow up with the top bidder to close the gap privately.
How reserve prices actually work.
Confidential by design
Unlike a starting bid, the reserve is hidden from bidders. They see only whether the lot has “met reserve,” not the exact number protecting the seller.
Protects the consignor
The reserve sets a floor below which the seller is not obligated to sell, guarding against an item going for far less than its agreed value.
Drives bidding behavior
Pairing a low starting bid with a hidden reserve invites early action while keeping the seller protected until competitive bidding catches up.
Triggers a buyback or pass
If the high bid never reaches the reserve, the lot is bought back (passed). The auctioneer may then negotiate a post-auction sale with the leading bidder.
Frequently asked questions
What is the difference between a reserve price and a starting bid?+
The starting bid is the public price where bidding opens and is visible to everyone. The reserve price is the confidential minimum the seller will actually accept. A lot can open at a low starting bid to encourage participation while a higher hidden reserve still protects the consignor.
What happens if bidding does not meet the reserve?+
If the highest bid stays below the reserve, the lot does not sell at the hammer — it is “bought back” or passed. The auctioneer often follows up with the leading bidder to negotiate a private post-auction sale, or the lot is re-listed.
Is a reserve price the same as an absolute auction?+
No. An absolute (or no-reserve) auction sells to the highest bidder regardless of price, with no minimum floor. A reserve auction sets a confidential minimum, so the seller retains the right not to sell if that figure is not reached.
Why keep the reserve secret from bidders?+
A visible reserve can anchor bidders to that exact figure and suppress competition above it. Keeping it confidential lets natural competitive bidding push the price as high as the market will bear, while the floor still protects the seller behind the scenes.
