Included with every TCG card

  • Four subgrades: centering, corners, edges and surface
  • A 1–10 composite grade
  • A digital report with front and back scans, corner close-ups, centering measurements and a surface heatmap
  • A tamper-evident slab with a unique cert ID
  • Permanent online cert verification buyers can check without an account

Built for foils and full-arts

Foil, holo and full-art surfaces often lose points to wear that is hard to see by eye. Your report's surface heatmap marks where the scan found wear and print marks, so you can see what shaped the surface subgrade.
