OCE Grading uses a highly accurate 10 point grading scale (1-10). Cards which exhibit high-end qualities within each particular grade may receive a half-point grade increase (eg. 9.5). To determine the final grade of a card we assign it four subgrades: surface, centering, corners and edges. These four subgrades are used in an algorithm to calculate a cards final grade. 

 

Below are OCE Gradings standards for each subgrade:
