Selling a Painting at Auction: A Complete Guide

Selling a painting at auction exposes the work to a competitive field of motivated buyers. A well-prepared consignment file can make a significant difference in the final hammer price.

What Determines a Painting's Value

The Artist and Signature. A legible signature, or a documented attribution, is the primary criterion.
Provenance. This includes invoices, exhibition catalogs, gallery labels, and a documented history of ownership.
Condition. Craquelure, restorations, surface dirt, and the state of the stretcher and frame are all assessed.
Subject, Period, and Size. Two works by the same artist can have vastly different values depending on these factors.

What to Prepare for a Valuation

Clear photographs: the entire work (front), the back, the signature, any labels, and any visible damage.
The dimensions, medium (e.g., oil on canvas, gouache), and information about the frame.
Any provenance documents or certificates of authenticity you possess.

The Auction Process

Appraisal. Based on your photos, a specialist provides an estimated value range. Learn more about our valuation process.
Authentication. For works with uncertain attribution, an expert opinion can provide security and confidence for the sale.
Reserve Price. This is the confidential minimum price below which you agree not to sell. It is set in consultation with the auction house.
Consignment and Sale. This stage includes professional photography, cataloging, marketing, and the auction period itself.
Settlement. After the auction, the buyer submits payment. Your proceeds are transferred to you within 48 hours of our receiving the buyer's payment. For clients who register before December 31, 2026, there is no seller's commission. See our guide to comparing auction fees.

Common Mistakes to Avoid

Cleaning or retouching the painting yourself. An amateur cleaning can significantly decrease its value.
Changing the frame or removing labels from the back. These are part of the artwork's history and provenance.
Setting an overly high reserve price. A lot that goes unsold (is "bought in") is often harder to sell later.
Hiding condition issues. Disclose them upfront. An informed buyer bids with confidence.
Submitting blurry or dark photos. This will only delay the appraisal process.

How to Choose a Reserve Price

Start with the low and high estimates provided by the auction house. Then, research recent auction results for comparable works: same artist, same medium, similar size. A reserve price set near the low estimate encourages competitive bidding and can help the work surpass its high estimate.

How to Photograph Your Painting

Use diffuse, natural light to avoid glare on the varnish.
Photograph the painting straight-on, first with the frame visible, then a shot of the artwork alone.
Take close-ups of the signature, the back of the canvas, any labels, and any areas of damage.
If helpful, place a common object next to the artwork to provide a sense of scale.

Documents That Add Value

Gallery invoices, certificates of authenticity, exhibition labels, old catalogs, and correspondence from previous owners are all valuable. For a modern artist, inclusion in the catalogue raisonné or an opinion from the artist's official committee or rights holder can be crucial. Read "Modern vs. Contemporary Art: What's the Difference?" to understand why.

Frequently Asked Questions

Should I have the painting restored before selling? Not always. A poor or unnecessary restoration can reduce its value. We recommend seeking our advice before any intervention.

Can I set a minimum price? Yes, this is called the reserve price and is set confidentially with the auction house before the sale.

What if I don't have any documents or provenance? You can still request an appraisal. While a lack of provenance is factored into the valuation, it does not prevent a sale.
