Master the CGB Grading Scale with Confidence
Discover detailed criteria and clear explanations to accurately evaluate your card’s condition from pristine to damaged.
Each card submitted to the Collector Grading Bureau (CGB) is evaluated across four key categories and will receive Subgrades:
- Centering – How well the card’s image is aligned from left to right and top to bottom.
- Surface – The condition of the card’s front and back, including gloss, print quality, scratches, or blemishes.
- Edges – The sharpness and cleanliness of the card’s borders.
- Corners – The sharpness, wear, or rounding of each corner.
Each category receives a numerical score based on CGB’s 1–10 grading scale.
The final grade is determined by calculating the average of these four subgrades.
Rounding Rule
- If the combined average ends in 0.5 or higher, it is rounded up to the next whole number.
- If the combined average ends in below 0.5, it is rounded down to the nearest whole number.
Example:
If a card receives the following subgrades:
- Centering: 9
- Surface: 10
- Edges: 7
- Corners: 8
Average: (7 + 10 + 8 + 9) ÷ 4 = 8.5
Final Grade: Rounded up to 9 (Mint) + 0.5 Eye Appeal
This method ensures that every CGB grade reflects both the technical accuracy of its measurable aspects and the overall balance of its visual appeal.

What criteria define the CGB grading scale?
Explore precise explanations of each grade to assess your card’s condition with confidence and accuracy.
While a large part of grading is objective — identifying print defects, surface wear, corner and edge imperfections, centering, and other measurable flaws — there is also a subjective element to every evaluation. The best way to understand this subjective component is to ask: What would collectors and the market reasonably accept for this particular issue?
The majority of grading decisions are made using a consistent and objective standard, but the eye appeal of a card can influence the final result. This subjective factor typically comes into play when a card’s centering or overall presentation is in question.
For example, while most cards fall clearly within the centering guidelines for a specific grade, some may fall just inside or slightly outside the printed standards. In these cases, CGB graders reserve the right based on the overall strength or weakness of the card’s appearance to make a professional judgment call on the final grade.
At the Collector Grading Bureau, our goal is to balance precision with fairness, ensuring that every card is graded accurately, consistently, and with a keen understanding of what truly defines its quality and appeal within the hobby.
