^Population in Higher Grades calculation
Population in Higher Grades reflects the number of coins in the NGC Census population report in higher numeric grades and strike characters. For example, the Population in Higher Grades for a coin graded MS 67 BN would reflect the population for MS 67 RB and MS 67 RD (since these are higher strike characters) as well as all the population for higher numeric grades. Likewise, if a coin is graded MS 70 PL, the Population in the Higher Grades would reflect the population for MS 70 DPL (if any).
Total Graded by NGC: How is this calculated?
The population in a given grade reflects the number of coins graded by NGC with that exact grade, designation (e.g. + or Early Releases) and strike character (e.g. BN or Ultra Cameo). The population “in higher grades” reflects the number of coins graded by NGC with a higher grade and/or better designations and strike characters. If the coin’s label has a signature (e.g. Mercanti Signature), the population will be limited to coins with that exact signature.
For example, if the coin’s grade is NGC AU 58 BN, the population shown will reflect all coins graded NGC AU 58 BN. The population “in higher grades” will include coins graded NGC AU 58 RB, NGC AU 58 RD, NGC AU 60 BN, etc.
