How Collectors Can Benefit from Using NGC Census Data
Coin collectors often refer to the grading services’ census reports to study how populations have increased. Additionally, collectors can educate themselves and determine the right acquisitions for their collection. Furthermore, understanding the number of coins in each grade can help separate a collection from the pack. In many cases, a single grade can means hundreds or even thousands of dollars in cost difference for a coin.
The World’s Largest, Most Trusted Numismatic Grading Service
The NGC Census is an up-to-date population report showing the latest number of coins, tokens and medals graded by NGC for every type and grade.
With an unparalleled commitment to accuracy, consistency and integrity, NGC is the world’s largest and most trusted third-party grading service for coins, tokens and medals. Since 1987, NGC has graded more than 52 million coins, each one backed by the industry-leading NGC Guarantee.
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. Data is updated weekly and includes all specimens graded by NGC.
