One Piece Card Game Tier List
Compare One Piece Card Game sets through a ratio-based market ranking built from card value versus sealed box cost.
This tier list ranks One Piece Card Game sets with a simple and explicit rule: the final tier is based on the ratio between the average value of the cards in the set and the current box cost of the related sealed product. It is designed as a fast market signal for collectors and speculators who want to compare sets on a consistent data model.
How the tier list is calculated
The production script computes several market metrics, but the actual tier assignment uses only one final rule: test_ratio = EV / box_cost. EV is the average price of the cards found in the set, while box cost is taken from the related sealed product when available.
- Cards included in the calculation:
For each set, the script loads documents fromCardswheresetIdmatches the set,typeisCards, and, in production mode, the item is bothvisibleandverified. - Price selection logic:
The script reads prices fromCards.marketDataand uses the first valid positive value found in this order:price,priceTrend,price7d,price30d,price90d,price1d,priceSecondary,pricePrimary. - Box cost logic:
Box cost is resolved throughsealedIdby looking up the related sealed product inCards. If no valid market price is found, the script falls back to $200.00. - Core metrics produced:
The script stores and prints several metrics for analysis:EV,median,stdev,pct_gt10,sum_gt10, top 3 cards over $10, andICV. These are useful for reading set quality, but they do not decide the final tier.
Tier assignment rule
| Tier | test_ratio = EV / box_cost | Meaning |
|---|---|---|
| S | >= 0.30 | Highest EV relative to box cost |
| A+ | >= 0.20 | Strong EV relative to box cost |
| A | >= 0.12 | Good EV relative to box cost |
| B | >= 0.06 | Moderate EV relative to box cost |
| C | < 0.06 | Weak EV relative to box cost |
Example: If a set has an average card value of $48.00 and a box cost of $160.00, the test ratio is 0.30, so the set lands in Tier S.
In short, this page should be read as a ratio-based market ranking, not as a full collectible quality score. ICV, price concentration, and the number of cards above $10 are still useful supporting signals, but the tier itself is driven only by EV versus box cost.
