Our auctions are held in the spring and autumn. Our catalogues are produced in printed form. Hardcover, high image quality and accurate descriptions are a matter of course for us. Since high quality standards as well as the love of numismatics are important tu us, these aspects are included in the descriptions of the auction lots. The estimates are based upon the market and provide a fair indication of the value.
The "Gantbeamte" is an important feature at all our auctions in the canton of Zurich. This state official supervises the proceedings, writes a further log and has the last word. In the case of any doubts, he officially confirms the final bid and gives consignors and bidders a certainty that only exists in Switzerland.
After the auction, we check and insure the delivery of the auctioned items to the address specified by you. Of course, you can also collect the purchased items in person. Following your purchase, we will gladly assist you with processing and support in terms of administrative matters and the export of your valuables.
