Your consignment
Full attention for your collectibles
We hold our internationally renowned auctions every spring and autumn. Our experts ensure professional handling – both before the auction and after the hammer falls. This includes hardcover catalogues with perfect image quality and accurate descriptions of each individual item. In order to reach collectors around the world, each auction can also be viewed online and is published on our own platform as well as on Sixbid and Numisbids.
We greatly value personal contact with our customers. This is why SINCONA auctions always take place as traditional floor auctions at our headquarters in Zurich. You also have the option of bidding online via live bidding – securely, reliably and in real time.
