NGC is the official grading service of the PNG

Numismatic Guaranty Corporation of America (NGC®)

1907 HighRelief obv

When NGC was founded in 1987, it heralded the introduction of a new standard of integrity in coin grading. 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 numismatic professionals ensure 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.
Grading is a team effort, with at least two professional numismatists examining every coin. To maintain impartiality, NGC’s coin graders cannot be involved in the commercial buying and selling of coins. Each coin is examined by one NGC coin grader at a time, who enters the coin grade into the system. The NGC grading team’s only interest is in determining accurate grades for coins. Once graded, the coin is sonically sealed in a holder made of inert material that won’t affect the encapsulated coin.
Beyond its grading services, the NGC website is the number one resource for research tools including the US Coin Price Guide, NGC World Coin Price Guide, Chinese Modern Coin Price Guide, NGC Auction Central and NGC Coin Explorer.
NGC is the official grading service of the Professional Numismatist Guild. NGC is also the Official Grading Service of the American Numismatic Association (ANA).
At NGC we pride ourselves in our uncompromising standards and a commitment to integrity that makes us the leader in coin certification.
