About Numismatic Guaranty Company® (NGC®)
NGC, the world's largest and most respected third-party coin grading service, was founded in 1987. From the beginning, NGC has committed itself to developing an impartial, trusted standard of consistent and accurate grading. To uphold this commitment, NGC's full-time grading professionals are no longer active in the commercial coin marketplace, and are prohibited from buying or selling coins to ensure impartiality. As NGC has grown to become the leader in third-party grading services, we have maintained a steadfast and uncompromising commitment to this standard. Learn more at NGCcoin.com.
