What the AI grades
Centering
Border ratios on front and back. 55/45 or better required for high grades. Advanced mode shows exact L/R and T/B ratios.
Corners
All four corners examined for fraying, rounding, wear, or creasing. Advanced mode gives per-corner scores.
Edges
All four edges checked for nicks, chips, roughness, or splitting. Advanced mode uses dedicated edge photos.
Surface
Front and back for scratches, print lines, stains. Advanced mode uses a close-up for micro-defect detection.
GemRate Labs uses Claude's vision AI. Results are estimates — not official PSA, BGS, or SGC grades. Use this to decide whether a card is worth the cost of professional submission.
