Should You Grade Your One Piece Card? ROI Calculator + Guide
Grading isn’t always worth it. The right question isn’t “Is this card cool?”—it’s “Will the graded premium exceed all costs?” Here’s a collector‑friendly way to decide.
When does grading pay off?
If a card’s graded premium is significantly larger than fees and shipping, grading can be a smart move. High‑value chase cards usually qualify; mid‑range cards often don’t unless the condition is pristine.
ROI formula
ROI = (graded value − raw value − grading fees − shipping/insurance) ÷ total cost
If your ROI is negative or barely positive, keep the card raw and track its price instead.
Condition checklist before you grade
- Clean edges with no whitening
- Centering within tolerance
- No surface scratches or print lines
- Strong corners with no fraying
