About CGC Trading Cards Grades

What do the CGC Trading Cards grades mean?

CGC Trading Cards uses a highly accurate 10-point grading scale, with grades ranging from 10 (Pristine) to 1 (Poor). To determine a card's grade, graders consider factors such as centering, manufacturing and handling defects, how well the card has been preserved, evidence of play, scuffing, indentations, soiling, fading and more.

What are sub-grades?

Sub-grades are grades that provide further detail into the card's overall grade. There are four sub-grades: Centering, Surface, Corners and Edges.

Does CGC Trading Cards offer sub-grades?

Yes, CGC Trading Cards offers sub-grades for an additional £14 fee per card (excluding VAT) or £16.80 (including VAT).

How do a card’s sub-grades relate to its final grade?

CGC Trading Cards has developed a proprietary algorithm to determine a card’s final grade based on its sub-grades. While we can’t reveal how we arrive at a final grade and sub-grades for a specific card, we can share some guidelines. First, it is important to note that the final grade is not simply an average of the sub-grades. Rather, it is based on numerous rules that are built into CGC Trading Cards’ proprietary systems and grading process. For example, the final grade can be no more than 1 point higher than the lowest sub-grade. In addition, if the two lowest sub-grades are the same, then that is the final grade for the card. For more information on CGC Trading Cards’ grades, including detailed explanations for each grade and sub-grade, see the CGC Trading Cards Grading Scale.
