The New York International Numismatic Convention (NYINC) is the premier United States convention for world and ancient coins, held every January in midtown Manhattan. It is the leading venue where international dealers and the major auction houses come together for foreign and ancient numismatics — a distinct focus from the U.S.-federal-coinage shows.
Alongside the dealer bourse, NYINC anchors a dense week of auction sessions from houses such as Heritage, Stack's Bowers, Classical Numismatic Group, Spink and the New York Sale.
For more than five decades NYINC has been the foremost U.S. gathering for collectors and dealers of world and ancient coins, building a calendar of January auctions and society events that has become a fixture of the international numismatic year.
Expect a specialist bourse weighted toward ancient, medieval and world coinage rather than U.S. issues, running in parallel with multiple major auction sessions and lot viewing. The convention also hosts club and society meetings, lectures and educational events that draw the international collecting community to New York each January.
