PSA Pre-Grading Checklist for Trading Cards

Use this PSA pre-grading checklist to screen a trading card before you decide whether to submit it. BAO Grade is independent of and not affiliated with Professional Sports Authenticator (PSA). A BAO estimate cannot guarantee a PSA grade. The safest reference for PSA-specific requirements is always PSA’s current published grading standards and service information.

1. Start with authenticity and alteration concerns

Pre-grading is not authentication. PSA describes authentication as a step that occurs before grading and publishes reasons a card may not receive a numeric grade, including certain forms of trimming, restoration, recoloration, altered stock, cleaning and questionable authenticity. Do not try to “improve” a card before submission with whitening, recoloring, pressing, polishing or another alteration. If authenticity or alteration is uncertain, a photo-based condition score cannot resolve that question.

2. Measure centering without forcing a grade

Measure the printed border from the physical card edge, not from the edge of a sleeve or camera crop. Use the BAO centering calculator for the ratio, then compare that measurement with PSA’s current published standards rather than relying on an old screenshot or a copied threshold from a forum. PSA’s standards also note that eye appeal and grader judgment can matter around borderline cases, so a ratio alone should not be presented as a guaranteed label.

3. Inspect corners and edges under magnification

Check all four corners from the front and back for whitening, softness, rounding, crushing or bends. Trace every edge for chips, roughness and discoloration. Dark card backs can make small white spots easy to see, while light borders can hide edge wear. A sleeve or slab can obscure the exact physical edge, so record that limitation rather than assuming the underlying card is clean.

4. Rotate the card to inspect the surface

Use soft light first, then a second angled light to reveal scratches, print lines, dents, impressions, creases, staining, clouding or surface contamination. A photograph taken from only one lighting angle may miss shallow defects. Holographic and textured cards are especially sensitive to reflections. If a suspected defect moves with the reflection, capture another angle before counting it as physical damage.

5. Decide whether professional grading serves your goal

Condition is only one part of the submission decision. Consider why you want the card graded, the current service level, declared or insured value requirements, handling and shipping risk, and whether the likely outcome would matter to you. PSA’s service details and turnaround estimates can change, so use its current official service page when you are ready to submit rather than relying on a static BAO article.

How BAO fits into PSA pre-grading

BAO can help organize visible evidence into centering, corners, edges and surface, and it can flag weak photographs that need recapture. It cannot duplicate an in-hand PSA examination, authenticate every card, detect every alteration or predict discretionary decisions. Use BAO to reduce obvious submission mistakes and identify areas that need closer inspection, then use PSA’s own current standards for the final submission decision.
