Should You Grade Your One Piece Card? ROI Calculator + Guide

By Haki TCG Team

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

Use Haki TCG before you submit

Scan the card, record the raw value, and save it to your watchlist. That gives you a baseline for ROI and makes it easy to monitor post‑grading value changes.
