Private sale or auction: choosing the right exit for a major work

10 October 2026

Every owner of an important work eventually faces the same decision: consign it to an auction, or sell it privately. Above €100,000 the choice is worth making carefully, because the two routes differ in what they cost, what they reveal, and what they leave behind. This note sets out the differences as they apply in practice, and when each route is the right one.

What an auction really does

An auction house offers three things: a date, an estimate, and a public competition. For the right work, that competition can produce a spectacular price. Or, if there is a lack of buyers, the seller is informed just before the sale and can lower the reserve price. But the costs are structural. The seller pays a commission, typically between 10% and 25% of the hammer price. The buyer pays a premium on top, commonly 25%, which suppresses what bidders are willing to bid. And everything is public: the estimate, the result, and usually the consignor’s identity are published and archived permanently.

There is also the risk the catalogue never mentions. If bidding stops below the reserve, the work is bought in. It becomes publicly associated with a failed sale, and the next time it appears, buyers know. Collectors call such a work burnt, and the discount it carries is real.

What a private sale really does

A private sale inverts the mechanics. Instead of offering the work to everyone at once, it is shown to a small number of qualified buyers who have already expressed interest in exactly that artist or period. The price is negotiated directly. Nothing is published, and neither party’s identity needs to be disclosed until the transaction settles.

The trade-offs are real. A private sale forgoes the competitive bidding that occasionally produces an exceptional price, and it depends on the work actually being matched to the right buyers, which requires a network rather than an advertisement.

The arithmetic on a €500,000 work

Take the average Finarta transaction, about €500,000. Through Finarta, the seller pays 3%, or €15,000, and the buyer pays 3%. At auction, the seller’s commission on the same result would typically be €50,000–125,000, and the buyer would pay €125,000 in premium on top of the hammer. Both sides of a private transaction keep more, and the buyer’s saving is what allows the seller’s net price to hold.

When the auction is the right choice

Auctions still earn their place. A work with broad, well-documented secondary demand and an owner who wants a public price record may do better under the hammer. An estate that needs every asset sold by a fixed date may value the auction’s binding calendar. And a genuinely fresh-to-the-market work with several known collectors competing can justify the public exposure.

When the private sale wins

The private route wins whenever discretion carries value: estates and successions that should not appear in a catalogue, collection restructurings that should not signal a change of taste, and any owner who cannot afford the word burnt attached to their work. It also wins on speed where no fixed date forces the decision, since a private negotiation runs on the parties’ schedule, not a season’s.

How the decision is made in practice

At Finarta Art Club, members do not choose between the two routes blind. A work is submitted confidentially, matched against the active requests of vetted collectors and a network of 450+ top-tier galleries in 30 countries, and real indications of interest come back before anything is consigned anywhere. If the private indications are strong, the work sells quietly at a 3% seller fee. If they are not, the owner has learned something no auction estimate would have told them, at no public cost.
