Grading Standards
Four components. One final grade.
Every card is evaluated on four core components. The final grade is determined after senior review and cannot be changed without an official audit log.
Centering
Front and back border ratios are measured to ensure symmetry.
Corners
Four corners are inspected for rounding, whitening, and minor chipping.
Edges
Card edges are evaluated for integrity, including fraying and chipping.
Surface
The surface is checked for scratches, print defects, gloss, and indentations.
