Is PreGradeCards accurate compared to PSA?

Our AI is trained on over 1.2 million PSA-graded cards and predicts the final grade with 95% accuracy within 1 point.

Why use PreGradeCards before PSA?

To save money. PSA charges $25+ per card regardless of the grade. PreGradeCards ($0.19) filters out low-grade cards so you only submit the winners.

Yes. We use the standard 1-10 Gem Mint scale, but we also provide sub-grades (Corners, Edges, Surface, Centering) which PSA does not reveal.

Don't fly blind. Compare our AI pre-grading with Professional Sports Authenticator (PSA) to see how you can save money and improve your return on investment.

Before submitting to PSA: Filter out cards that won't grade a 9 or 10.
Buying Raw Cards: Quickly assess condition before purchasing online or at shows.
Checking Centering: PSA is strict on centering (60/40 front). Our tool measures this precisely.

Don't send 20 cards to PSA just to get 5 Gem Mints. Send only the 5 that will pass, and save the rest for raw sales.
