PSA vs CGC: Understanding Grade Differences and the Role of Centering

How PSA and CGC Grading Scales Compare

Both PSA and CGC use a 1-10 grading scale for trading cards. PSA's highest standard is Gem Mint 10, while CGC offers both a Gem Mint 10 and a Pristine 10 tier, the latter requiring perfect subgrades in centering, corners, edges, and surface. PSA 10 cards tend to carry the highest resale value and are the most liquid in the market. CGC is known for faster turnaround times and often lower submission costs, making it appealing for some collectors and sellers.

Centering Requirements: What Gets You a 10?

Centering is a critical subgrade in both systems. For a top grade (10) from either PSA or CGC, your card typically needs front centering around 55/45 or better. Back centering standards are generally more lenient but still important. Neither PSA nor CGC publish exact tolerances for every grade, and requirements can change, so always review their official guidelines before submitting. To avoid guesswork, measure your card's exact centering using the Midpoint app for iOS or Android before deciding where to send it.

Other Subgrades: Corners, Edges, and Surface

• Centering is just one factor. Both PSA and CGC also assess corners, edges, and surface quality.
• Even with perfect centering, flaws in other areas can prevent a card from achieving a 10.
• CGC's Pristine 10 requires all four subgrades to be perfect, making it harder to achieve than a Gem Mint 10 from either service.

Which Grader Should You Choose?

If resale value is your top priority, PSA 10s are generally the most sought after. If you want a faster, often less expensive grading process or are aiming for a Pristine 10, CGC may be a good choice. Since centering standards for a 10 are nearly identical, your card will often receive a similar grade from both, provided other subgrades are equal. Always measure your card's centering in advance with Midpoint to set realistic expectations and avoid wasted grading fees.
