How Collectors Can Use NGC Census Data

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. Collectors often refer to the grading services’ census reports to study how populations have increased, as well as help determine the right acquisitions for their collection.

Understanding a coin’s population

Population, or the number of coins in each grade, is key for collectors to establishing a coin’s rarity. In many cases, the grade can mean a difference of hundreds or even thousands of dollars in price. Understanding the populations can help you make better acquisitions.

Collectors Trust NGC

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.

Impartial, accurate and consistent

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.
