PSA 10 vs SGC 10: Real Differences and the Role of Centering

PSA 10 and SGC 10 are both top trading card grades, but their centering standards and grading approaches have important differences that can affect your submission success.

PSA 10 vs SGC 10 - The Real Difference & How Centering Decides

How PSA and SGC Judge Centering for a 10

PSA and SGC both require excellent centering for a Gem Mint 10, but their published standards differ. PSA specifies that a 10 needs approximately 55/45 to 60/40 or better centering on the front. SGC, widely respected for vintage cards, requires centering that appears very even, but does not publish exact ratios. Instead, SGC judges by the visual balance of the borders. In practice, both companies expect near-perfect centering for a 10.

Why Centering Matters for Grading

Centering is just one of several factors in a card’s overall grade, alongside corners, edges, and surface. However, off-center cards will not achieve a 10 from either PSA or SGC, regardless of other condition aspects. Precise centering measurement is critical before you submit a card, especially with valuable or vintage cards.

Measuring Centering: What You Can Do

PSA publishes specific centering guidelines (about 55/45 to 60/40 front).
SGC expects near-even borders, but exact tolerances are not published.
Always check each grader’s current published standards before submitting.
You can measure your card’s exact front and back centering using the Midpoint app, which detects borders and calculates centering ratios from a photo. This helps you know where your card stands before paying for grading.

Choosing Between PSA 10 and SGC 10

Collectors often prefer PSA for modern cards and the broadest resale market, while SGC is a favorite for vintage due to its reputation and slab design. Both grades are highly respected, but the choice may come down to card type and your goals. Since SGC does not print sub-grades and uses visual judgment for centering, borderline cases may receive different results than PSA’s ratio-based approach.

Key Takeaways Before Submitting

Both PSA 10 and SGC 10 require excellent centering and overall card condition.
PSA’s centering standards are more specific; SGC’s are more visual.
