About
Numismatica Ars Classica NAC AG is widely regarded as one of the world's foremost auction houses dedicated to ancient and world coins. Founded in Zurich and now operating across London, Milan, and Chicago, NAC has built an unparalleled reputation for handling some of the most significant numismatic collections ever sold at auction — including the legendary Traveller Collection, with an anticipated value exceeding $100 million. NAC's platform enables collectors, historians, investors, and institutions to participate in world-class coin auctions from anywhere. Users can browse detailed online catalogues, register for live bidding sessions, and access comprehensive price-realized archives to inform their collecting and investment decisions. Each auction features rigorous scholarly cataloguing with high-resolution imagery, historical context, and expert estimates. The firm regularly handles extraordinary rarities — from Greek decadrachms and Roman aurei to British pattern crowns and Italian Renaissance gold coinage. Past highlights include an Athens Decadrachm that realized CHF 800,000 and a Stymphalos Stater that doubled its estimate at CHF 500,000. NAC serves a global clientele ranging from seasoned private collectors and institutional buyers to first-time participants entering the numismatic market.
