NGC: Coin Grading's
Standard of Integrity
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 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.
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.
At NGC we pride ourselves in our uncompromising standards and a commitment to integrity
that makes us the leader in coin certification.
