Numismatic Guaranty Corporation (NGC)
NGC was founded in 1987, and for coin grading, its opening heralded the introduction of a new standard of integrity. From the beginning NGC focused on only one objective, a standard of consistent and accurate grading.
As NGC has grown to become the leader in third-party grading services, we have maintained a steadfast and uncompromising commitment to this standard. The knowledge, integrity and dedication of NGC’s team of grading experts ensures you a level of grading consistency unparalleled among grading services. This record of consistency, built over the years, has helped to foster greater stability throughout the rare coin marketplace.
To ensure impartiality and accuracy, three numismatic experts, each with decades of successful professional experience in rare coins, evaluate each coin submitted for grading. A grading finalizer assigns a final grade and the coin is then sonically sealed in a protective, inert plastic holder. NGC’s full-time grading experts are no longer active in the commercial coin marketplace, and are prohibited from buying or selling coins to ensure impartiality. Most have been with NGC for many years. The NGC grading team’s only interest is in determining accurate grades for coins.
At NGC we pride ourselves on our uncompromising standards and a commitment to integrity that makes us the leader in coin certification.
