PSA 10 vs TAG 10: Real Differences and How Centering Affects Your Grade
PSA 10 and TAG 10 are both top grades, but they use different methods and standards - especially for centering. Here’s what you need to know before submitting your card.

How PSA Grades Centering for a 10
PSA uses expert graders to visually assess cards and assigns a single overall grade. For a PSA 10, the published standard is front centering roughly 55/45 to 60/40 or better. PSA does not publish a more exact requirement, and centering is only one aspect - corners, edges, and surface also matter. Always check PSA’s most current standards before submitting.
How TAG Grades Centering for a 10
TAG (Technical Authentication & Grading) uses computer vision and algorithmic analysis, not human eye. Every card receives a centering sub-score, reported transparently. To achieve a TAG 10, the centering must be extremely close to perfect. TAG's centering assessment is strict and precise, so even slight centering issues can prevent a 10, regardless of other subgrades.
Why Centering Matters More with TAG
- TAG’s image analysis is very similar to how Midpoint measures centering.
- Even a small centering flaw can mean the difference between a TAG 10 and a lower grade.
- Knowing your exact centering percentages before submitting is critical for TAG grading.
How to Measure Your Card’s Centering Before Submitting
You can measure your card’s centering precisely using the Midpoint app (available for iOS and Android). The app calculates exact front and back centering percentages from a single photo, so you know where your card stands before you pay to submit it - especially important for TAG, but also helpful for PSA and other graders.
Other Grading Factors
Remember, centering is only one part of grading. Both PSA and TAG consider corners, edges, and surface condition. A card with perfect centering but flaws elsewhere may not achieve a 10. Review all grader standards and measure your card’s centering in Midpoint to make informed submission decisions.
