Executive Summary: Grading ROI Formula
Grading Expected Value (EV) measures statistical profitability across grade outcomes. Submitting a card is profitable when the expected sale value exceeds the total investment:
Rule of Thumb: Modern cards generally require a minimum 2.5x price multiplier between raw Near Mint and PSA 10 to absorb grading fees ($19.99–$24.99/card) and shipping risk.

The 4-Point Pre-Grading Checklist
PSA 10 requires 55/45 to 60/40 on the front and 75/25 on the back. Measure using millimeter precision or an optical centering card.
Inspect under directional raking LED light. Look for factory print lines, roller indents, and holographic foil scratches.
Examine all 4 front and rear corners under a 10x jeweler loupe. Any visible white fiber exposure knocks the card down to PSA 9.
Check edges for rough factory die-cutting, chipping, or foil silvering on the top and bottom borders.
