How is the tierlist is calculated?

Our Tier List ranks One Piece TCG sets based on their expected value per booster box, distribution of high-value cards, and overall collectibility. It’s designed to give collectors and investors a clear picture of which sets offer the best return.

1. Pullable Cards Only:
   We analyze only the cards that can realistically be pulled (*) from booster packs — ignoring starter decks, promo packs, and tournament kits. (*) Only specific rarities are considered: SR, SEC, L, SP, and DON!!.
2. Latest Ungraded Prices:
   For each card, we use only the most recent ungraded price available in our database to reflect real-time market conditions.
3. Three Key Metrics Are Calculated:
   • EV (Expected Value per Box): The average value of all pullable cards in the set. Higher EV means better monetary return.
   • ICV (Index of Concentration Value): Measures how much of the value is concentrated in just a few top cards. A lower ICV means value is more evenly spread.
   • % of Cards Over $ 10.00: Shows how many pullable cards in the set are worth more than $ 10.00 — a strong indicator of chase potential.
4. Tier Assignment Rules:

   Tier	EV per Box	ICV	% Cards > $ 10.00
   S	> $ 60.00	< 0.70	> 20%
   A+	> $ 40.00	< 0.75	> 15%
   A	> $ 30.00	-	> 10%
   B	> $ 30.00	-	> 5%
   C	< $ 20.00	-	< 5%

5. Example:
   A set with an EV of $ 85.00, ICV of 0.72, and 22% of its pullable cards worth more than $ 10.00 would be classified as Tier A+.

This system is designed to balance both upside potential and risk. By looking at value concentration and overall spread, it helps distinguish between sets with 1-2 ultra-expensive cards and those with broader collectible appeal.
