What Is a Reserve Price?
A reserve price is the minimum amount a seller is willing to accept for a lot at auction. If bidding does not reach the reserve, the item remains unsold — the auctioneer will "pass" the lot rather than hammer it down below the threshold. The reserve is typically confidential, known only to the seller and the auction house.
Reserve Price vs. Estimate vs. Starting Bid
These three figures are often confused by first-time sellers:
- Reserve price: The secret minimum. If not met, no sale occurs.
- Pre-sale estimate: The auction house's public guide price range, based on market research and comparable sales. Usually published in the catalogue.
- Starting bid / opening bid: The price at which bidding begins. Often set well below the reserve to attract early interest.
A common structure: starting bid at 50% of the low estimate, reserve at or just below the low estimate.
Why Setting the Right Reserve Matters
Setting your reserve too high is one of the most common mistakes sellers make. An unsold lot costs you in several ways:
- You may still owe a "buy-in" or unsold lot fee to the auction house.
- The item gets a public record of failure to sell, which can affect future buyer confidence.
- You lose the momentum and marketing exposure of the auction.
Conversely, setting no reserve (a "no-reserve" auction) can generate competitive excitement and sometimes push prices well above expectations — particularly for desirable or rare items.
How Auction Houses Advise on Reserve Prices
Most reputable auction houses will suggest a reserve range based on:
- Comparable sales: What similar items have sold for recently at auction.
- Current market demand: Is this category of item trending up or down?
- Condition and provenance: Documented history and strong condition command higher reserves.
- Seasonal factors: Certain categories perform better at specific times of year.
It's worth consulting with at least two auction houses before agreeing a reserve, as valuations can vary considerably.
Practical Tips for Setting Your Reserve
- Use the low estimate as a baseline: Many auction houses set the reserve at or slightly below the low end of their estimate range.
- Be realistic, not sentimental: Your emotional attachment to an item doesn't affect market value.
- Consider current market conditions: A softening market may warrant a lower reserve to ensure a sale.
- Ask about the buy-in fee: Know the financial cost of the lot not selling before you set an aspirational reserve.
- Review reserves right up until the auction: Many houses allow adjustments in the days before the sale — use recent comparable results to recalibrate if needed.
No-Reserve Auctions: When to Consider Them
For highly sought-after items — rare collectibles, items with strong provenance, or pieces in a specialist sale with a dedicated collector audience — removing the reserve entirely can be a powerful tactic. Bidders love the excitement of a no-reserve lot, and competitive bidding can easily exceed what a reserve would have secured. However, this strategy carries real risk for everyday items with less guaranteed demand.
Summary
Your reserve price is your safety net — but set it too high and you deny yourself a sale. Work closely with your auction house specialist, research comparable results, and approach your reserve as a market-informed decision rather than a personal valuation.
