With an unparalleled commitment to accuracy, consistency and integrity, Numismatic Guaranty Company (NGC®) is the world's largest and most trusted third-party grading service for coins, tokens and medals.
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. The combined expertise of the NGC grading team results in unparalleled accuracy and consistency.
NGC invested more than $1 million 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.
