A Population report is a reference guide prepared by a certification service that some collectors use to help assess the relative rarity of a certified coin. Population reports show the number of coins at different grade levels known by that particular certification service. Please keep in mind that rarity is only one factor to consider in determining the market value of a coin.

A Population report's accuracy is limited by characteristics inherent to the marketplace. You should consider these limitations to avoid being misled by the data in the Population report. For example, certain coins may appear rare because a certification service has very few records of that coin being graded. This may be explained by the fact that inexpensive coins are not usually submitted for certification, and does not indicate a higher value. As another example, certified coins removed from their holders without notice to the certification service may still appear in the data.

Note: In many cases, eBay has access to information only from the latest update processed. If you have recently had your coin certified, then it may temporarily not be included in the population report.
