Numismatic Guaranty Corporation (NGC)
With a firm commitment to accuracy, consistency and integrity, Numismatic Guaranty Corporation (NGC) is a leading third-party certification and grading service for coins, tokens and medals. Since 1987, NGC has graded more than 47 million coins, each one backed by the comprehensive NGC Guarantee.
NGC employs more than 30 full-time coin graders as well as outside consultants. To ensure impartiality, NGC and its full-time graders do not buy and sell coins commercially, and strict procedures are in place to prevent consultants from influencing the grades assigned to their own submissions.
NGC invested more than £500,000 in research and development to create the most advanced protective holder for coins, tokens and medals. Designed for long-term preservation, the NGC holder is used by the Smithsonian Institution and other museums around the world to protect their most treasured rarities.
Over the last decade, NGC has steadily expanded its services, now boasting two locations in Europe: NGC International UK Limited (NGC UK) in London, United Kingdom, and NGC International GmbH (NGC GmbH) in Munich, Germany. NGC hires locally to best assist collectors and dealers. You can contact our NGC UK team by phone +44 (0) 20 3968 3848 or via email [email protected]
