Total Graded by CGC: How is this calculated?
The population in a given grade reflects the number of collectibles graded by CGC with that grade and grade category (Universal, Qualified, Restored or Signature Series). The population "in higher grades" reflects the number of collectibles graded by CGC in a higher grade with the same grade category.
For example, if a collectible’s grade and grade category is CGC Universal 9.2, the population shown will reflect all collectibles graded CGC Universal 9.2. The population "in higher grades" will include collectibles graded CGC Universal 9.4, CGC Universal 9.6, etc. (Collectibles in the Qualified, Restored and Signature Series grade categories are calculated separately.)
