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.

All our auctions are also available online and published on platforms such as Sixbid and Numisbids to ensure that we reach collectors around the world.

Our auctions are held as traditional floor auctions at our premises in Zurich - personal contact with our clients is a top priority for us. However, thanks to reliable and delay-free technology, it is of course also possible to participate in the auctions in real time via the Internet from all over the world (SINCONA Live Bidding).

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.
