Selling with Koller Auctions

Seven steps, from proposal to payment

1. Valuation

Our specialists examine your works of art at our premises or in your home, without obligation and free of charge. Afterwards you receive our auction estimates and a detailed proposal for sale at auction.

2. Shipping

If you decide to sell with us, we organise the shipment from anywhere in the world to Zurich upon request. Sellers do not pay any Swiss taxes for cross-border consignments.

3. Expertise

Our specialists thoroughly research and catalogue the items entrusted to us, if need be with the assistance of internationally recognised experts and scholars.


4. Marketing

The auction catalogues are published digitally and in printed form and are sent to collectors worldwide. In the weeks previous to our four annual auction series, we also publish our magazine KOLLERview with a circulation of between 20,000 and 400,000 copies. KOLLERview presents highlights from upcoming auctions as well as a review of recent results. The presence of our digital catalogues on important international art and auction platforms, and marketing that extends far beyond Switzerland and Europe ensure that our auctions attract worldwide attention.

5. Preview

All items coming to auction are exhibited in our premises in Zurich, and highlights are shown in Geneva, Basel and Germany. For outstanding works we also organize previews in other cities, and we regularly exhibit important Asian objects in China. At these previews, collectors can obtain information about the individual auction items and speak with our specialists. We also send condition reports and additional photographs upon request and give personalised advice to prospective buyers.

6. Auction

At our classic saleroom auctions, interested parties can bid in person or live online, as well as by telephone or by leaving a written absentee bid. All bidders must be vetted and approved.

7. Payment

The proceeds of the auction sale are transferred to the seller after receipt of payment by the buyer, within six weeks after the auction.
