Grading Scale
We use an industry-standard grading scale from 1 to 10, including half-grades to precisely reflect the condition of your cards. The overall grade is based on four factors: surface, edges, corners, and centering (if applicable). The overall grade can be a maximum of +1 grade above the lowest sub-grade. For example, if your sub-grades are "10 - 9.5 - 9 - 7," your overall grade will be an 8. To achieve a 10 GEM MINT, you need three sub-grades of 10 and one with a minimum of 9. To earn a 10+ Perfect, all four sub-grades must be 10. Note: the sub-grades will not be displayed on the Ultra Compact label.
