How PSA normally grades a card

PSA first checks whether the card is genuine. If it passes authentication, PSA reviews condition and assigns a grade on its 1 to 10 scale, with 10 as the highest grade. The graded card is then sealed in a tamper-evident holder with a certification label.

Authentication Graders check whether the card is original and look for signs of trimming, recoloring, restoration or other tampering. Step 1

Condition review Centering, corners, edges, surface, gloss, focus and print quality all affect the final grade. Step 2

Encapsulation After grading, PSA seals the card in a protective holder with its grade and certification number. Step 3

Why centering matters

Centering compares the left-to-right and top-to-bottom borders of the card. A card can be sharp, clean and authentic, but still lose grade potential if the printed image sits too far toward one side. PSA's published standards allow tighter centering for higher grades and wider centering for lower grades.

Strong centering Borders look balanced on both axes. This gives the card better high-grade potential if the rest of the condition is clean.

Noticeable shift The image leans to one side. This can still grade well, but the condition ceiling depends on PSA's centering allowance for that grade.

Off center Large border imbalance usually lowers the numerical grade or can receive an off-center qualifier depending on the card and grade.

What collectors should check before grading

Corners and edges

Look for whitening, dents, lifted corners, rough cuts, chips and fraying. Even small edge wear can matter on modern trading cards.

Surface

Check under strong light for scratches, print lines, stains, fingerprints, dents, roller marks and pressure marks.

Centering

Compare border widths on the front and back. Front centering is especially visible to buyers and graders.

Authenticity and tampering

Cards with trimming, recoloring, restoration or questionable authenticity may not receive a normal numerical grade.
