Where academic rigour & esthetic value meet: Our vision of the numismatic market is based on a dual approach. We believe that true cataloguing must bridge the gap between academic numismatics and careful market analysis.
For us, a rare coin or medal is not simply a commercial commodity or a list of technical specifications; it is a historical artifact that demands academic responsibility, as well as a tangible asset that requires objective financial awareness.
We ensure every coin and medal in our auctions receives maximum exposure on the national and international numismatic markets, thanks to a large and vetted database of international collectors, professional numismatists, museums, and institutions located in all parts of the world, from Asia to the USA, and throughout Europe and the Gulf countries.
We leverage a comprehensive omnichannel promotion network allowing us to match the market reach of the industry’s largest auction houses. Among them are the websites Sixbid.com, Numisbids.com, and Drouot.com, as well as the live-bidding plattform AUEX where international customers can participate “live” in our floor auctions from any part of the world.
In 2015, we launched Ex-Numis®, the first provenance research service for Ancient coins. Using digital image recognition technologies (facial recognition) associated with a database of almost 1 million pictures extracted from old auction catalogues, it allows us to find lost provenances in seconds. For the last 10 years, with the help of Ex-Numis®, we have been able to recover more than 15’000 lost provenances for our consignors and our international clientele of collectors and institutions.
Postitive impact on our Hammer Prices:
For rare coins and medals, a rediscovered provenance can change a bidder’s perspective entirely, often increasing the final hammer price by 40% or more. By running every eligible consignment through our provenance research process, we ensure that no hidden, valuable information is left unrecorded before the auction.
In 2021 we received a small group of outstanding medals from the late Middle Ages and the Renaissance for sale. Among them was „La Calaisienne“, a large silver medal from Charles VII, which celebrates the end of the 100 Years’ War. Documented through historical provenance research, these masterfully cast work attracted intense interest from institutional and private connoisseurs, reinforcing our house’s ability to position highly complex, historic collections successfully in the international market.
This exceptional silver medal achieved a historic hammer price of 408,000 CHF (including fees), establishing the world record as the most expensive French silver medal ever sold at auction.
This landmark result was the direct outcome of combining all the core pillars of our auction strategy. Through meticulous historical research and art-historical cataloguing, we contextualized its immense cultural importance, while our cinematic storytelling videos and direct outreach to our international network of collectors and curators brought the piece to the attention of astute collectors, far beyond the sole world of numismatics.
