What to check before grading Underground Sea

  • Edges and corners: dark borders make chipping and corner whitening easy to see, and graders mark them down quickly.
  • Surface: tilt the card under a bright light to catch print lines, scratches, and indents that a straight-on photo misses.
  • Centering: PSA 10 allows roughly 55/45 to 60/40 on the front and 75/25 on the back.

Measure the borders with the card centering calculator, or read the AI card grading guide.
