About NGC

With a firm commitment to accuracy, consistency and integrity, Numismatic Guaranty Company (NGC®) is a leading third-party grading service for coins, tokens and medals. Since 1987, NGC has graded more than 60 million coins, each one backed by the comprehensive NGC Guarantee.

Our Grading

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.
