Centering
Front and back alignment, border balance, image placement, and overall visual symmetry.
Human judgment. AI-assisted precision.
IGC condition reviews are built around the physical characteristics collectors inspect most closely. The goal is consistency, clear documentation, and a grade that can be understood—not just displayed.
Front and back alignment, border balance, image placement, and overall visual symmetry.
Sharpness, touches, wear, fraying, softness, and structural integrity under close inspection.
Whitening, chipping, rough cuts, edge wear, and consistency across all four sides.
Scratches, print defects, dimples, staining, gloss, indentations, and visible surface flaws.

An IGC 10 reflects exceptional presentation across centering, corners, edges, and surface.
