What is PreGradeCards? How does AI card grading work?

PreGradeCards is an AI-powered card pre-grading service at pregradecards.com. It uses computer vision neural networks to analyze trading card scan images and predict the grade a card would receive from professional grading companies — specifically PSA (Professional Sports Authenticator), BGS (Beckett Grading Services), SGC (Sportscard Guaranty), and CGC Cards.

The AI evaluates all four grading criteria: corners (sharpness, whitening), edges (chipping, roughness), surface (scratches, print lines, dimples), and centering (left/right and top/bottom border ratio). Centering is measured at pixel level with 99.2% accuracy.

Why collectors use it: PSA Regular grading costs $79.99/card in 2026 with ~65 day turnaround. Submitting a card that comes back PSA 7 instead of PSA 10 wastes the entire fee. PreGradeCards pre-screens cards at $0.19 each, identifying which cards have 70%+ PSA 10 probability before collectors spend $79.99+ per card.
