Although AFA's grading scale ranges from 0 to 100 at increments of 5 units, typically AFA-graded Transformers score between 60 and 90 for their overall grade, with a large concentration between 75 and 85. The exact process by which the overall grade is determined is unknown, but it is always either the lowest of the 3 subgrades or 5 units higher than that. Thus, two figures with exactly the same subgrades may receive different overall grades. (E.g., if two different figures receive subgrades of 85 box, 90 window, and 90 figure, then one may receive an overall grade of 85—the lowest subgrade, and the other may receive a 90—the lowest subgrade plus 5.) In addition to the grade on the label, there may also be a "Y" or "U" after the grade, meaning "yellowed" or "uncirculated" (i.e., from an un
