Service, Quality, Reliability, Integrity

  • These are the keywords we have committed ourselves to as a mission statement!

Benefit from our worldwide auctions, our expertise and Zurich as an outstanding place for auctions.


We gladly accept consignments for our SINCONA Auctions on May 17-19, 2021, until February 2021. We're looking forward to hearing or reading from you!

Going once, going twice and...

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.

As a consignor, you will be able quickly to verify the professional handling before and after the auction. Our quality, our international clientele and our contacts to global numismatists ensure the success to which we have dedicated ourselves as SINCONA AG.
