Selling a collection is rarely an easy decision. It seldom begins with a price, but with a question: what will become of what has been gathered over decades?
We treat every consignment as what it is: the result of selection, patience and judgement. With us, your collection is not one among many. It stands at the centre of our work, from the first examination to the final payment.
Not every collection belongs in an auction. We buy Goldvreneli, Swiss circulating silver coins and modern bullion coins directly
at current rates. Inherited a coin collection? Please see our page for heirs.
Send us photographs or a list by email or WhatsApp. We will tell you which pieces are suited to auction and which are not.
We examine the coins in our premises at the Müllerhof, or at your home or your bank if the collection should not be moved.
We set out the terms, estimates and auction date in writing. From handover your coins are insured.
Every lot is studied, photographed and – wherever possible – given its documented pedigree.
You receive your lots with descriptions and estimates exactly as they will appear in the catalogue for your approval.
You can follow the sale in the saleroom or online. After the auction, we settle your account on the agreed date.
In 2015 we launched Ex-Numis®, the first online provenance research service for ancient coins. It rests on our digitised library of several thousand auction catalogues, the oldest from the late 19th century: almost a million images, which our image recognition compares in seconds.
Since then we have recovered more than 15,000 lost provenances. For you as a consignor, this is no academic detail. A documented provenance provides legal and ethical certainty, supports authenticity and can raise the hammer price considerably. Every eligible consignment goes through this process before it enters the catalogue.
We ensure that every coin and medal in our auctions receives the greatest possible attention, in Switzerland and on international markets. Over more than fifteen years we have built an extensive network, from international collectors and professional numismatists to museums and institutions, from Asia and the United States to Europe and the Gulf States.
Our sales also appear on Sixbid, NumisBids and Drouot, and through the AUEX live-bidding platform clients around the world take part in our auctions in real time. This digital network gives our consignments the reach of the largest houses in the trade.
Since September 2026 we have welcomed our clients at the Müllerhof, St. Niklausstrasse 1,
a listed country seat in the heart of Solothurn’s old town, with its own saleroom.
Solothurn lies on the direct railway line from Zurich to Geneva-Airport:
35 minutes from Bern, 45 from Basel and 55 from Zurich.
Parking is available at the building, and a lift provides step-free access.
Visits by appointment.
This is how we present important pieces. Take a few minutes for these medals and their stories.
