Expertise and appraisals - the expert's eye
Thanks to the experience of our specialists and their extreme attention to detail, Koller is able to identify even seemingly unremarkable works of art and to sell them for important prices. Following are just a few examples of million-franc discoveries:

June 2009: Koller auctions places a chest of drawers by the famous cabinetmaker to King Louis XIV, André-Charles Boulle, within the context of nine other nearly identical pieces, today in some of the world's most important collections. The work sells for CHF 963 000 / EUR 640 000.

September 2008: After research by Koller's specialists and associated experts, a previously unknown still life is able to be identified as a masterpiece by Ambrosius Bosschaert the Elder (1573-1621). At auction, the work sets a record for the artist at CHF 5.77 million / EUR 3.61 million.

September 1999: A small oil on copper that was initially appraised at "only" CHF 100 000 / EUR 62 000 is identified by Koller as being an important work by Mannerist artist Joachim Wtewael (1566-1638), and is sold for CHF 3.14 million / EUR 2 million, a world record for this artist.

Estate management: we handle everything
"Cherry picking," or choosing only the most interesting works from an estate and leaving the family to deal with the rest, is not a part of the business philosophy at Koller. We prefer to offer a complete service, finding the best sales platform for all of the items in an estate: either in our main auctions, or in our Koller West sales for more moderately-priced works.

Shipping: art without borders
Koller auctions' logistics management team works with international transport companies to insure the surest and most reasonable shipment of your works to and from Zurich. Our experience in these matters is considerable, especially since over 80% of our buyers and 20% of our consignors are from outside of Switzerland.

Insurance guidance: better safe than sorry
Koller's team of specialists are available to appraise works of art or entire collections for insurance purposes, and to recommend the appropriate insurance agency.

Restoration made to order
Koller Auctions has an in-house cabinetmaking workshop in close proximity to the main auction galleries. Clients thus have the possibility to have their purchases restored to their liking by professional and highly experienced craftsmen.

A family business
Koller Auctions Ltd is owned and operated by the Koller family. This independent and flexible structure provides a favorable working environment for Koller's department heads, who have been with the company for an average of 15 years. This in turn translates into a stable and efficient buying or selling experience for our clients, and the guarantee of quality that only comes from a company that stands behind its family name.
