One Piece TCG Glossary

The vocabulary that actually moves money in One Piece TCG — rarities, card types, and the grading and valuation terms behind every call we publish. Each definition is written to be exact and verifiable; where a term deserves a full read, we link it.

Rarities & card types

How One Piece Card Game rarities are labelled — and which ones actually carry secondary-market value.

LeaderL

The single card that defines a deck's colour(s) and starting life — it sits outside the 50-card main deck, one per deck.

Leaders anchor an archetype, so their alternate-art versions are among the most-collected cards in the game. A Leader's price is set by scarcity and art, not by a single tournament result.

The decks that won, and what to buy

Super RareSR

A high pull-rarity in a main set — above Rare, below Secret Rare — usually a strong character or playable card.

Most SRs are affordable and common enough that value comes from play demand, not scarcity. A cheap SR whose PSA 10 is bid up is a classic grading-arbitrage setup, not a fundamentals move.

Why the SR Bonney price is rising

Secret RareSEC

The top pull-rarity in a main set — almost always an alternate-art version of a marquee character.

First-set SEC alt-arts (e.g. Shanks, OP01-120) are the benchmark chase cards of the game: out of print, iconic, and thin on graded population. That intersection of scarcity and durable demand is what supports four-figure prices.

Manga RareMR

An ultra-rare treatment styled like a black-and-white manga panel, seeded at very low pull rates.

Manga Rares are often the single most valuable pull in a modern set. Because they're recent, raw supply can still be entering the market — verify recent graded sales, not listing prices.

Treasure RareTR

A premium alternate-art, exclusive-foil reprint — one per English set from OP-06 onward, pulling at roughly one per case.

TRs are English/international-only (Japanese boxes get God Packs instead), so the class is small and fixed — only ~11 mainline English TRs exist as of OP-16. That makes their opportunity window unusually tight.

Treasure Rares explained

Alternate ArtAA

A different illustration of a card that already exists, with the same game text — the collectible ‘chase’ version of a card.

Alt-arts (a.k.a. parallels) are where most collector value concentrates, because the artwork — not the gameplay — drives demand. A card being an alt-art of a playable card can add deck demand underneath the collector demand.

DON!! card

The resource card that powers your cards and attacks — the 10-card DON!! deck sits alongside your main deck.

Standard DON!! cards have no secondary value, but special alt-art DON!! promos (event and campaign exclusives) are collected. Round1's Red Bull-style crossovers are a good example of collectible promo DON!!/character art.

PromoP-

A card distributed outside booster products — via events, magazines, or brand collaborations — carrying a P- number.

Promos range from mass magazine bound-ins (broad supply, low value) to tiny event prizes (scarce, four-figure). Always price a promo by its distribution mechanics, not its ‘exclusive’ label.

God Pack

A rare special booster (mostly in Japanese boxes) where every card is a high rarity — Japan's chase incentive in place of Treasure Rares.

God Packs are why Japanese and English/international boxes carry different chase economics, and part of why Treasure Rares are an English-gated class.

Treasure Rares explained

Value & grading terms

The vocabulary behind a real valuation — how we separate a price from a number.

Sold comp

The price a card actually sold for (not the asking price) — the only sound basis for a valuation.

We anchor to where many independent buyers actually transact, discard the highest and lowest, and discount thin markets. A wall of high asks with few sales is a red flag, not a value.

How we price cards

Ask vs. sold

An ask is what a seller hopes to get; a sold price is what a buyer actually paid — only the second is real value.

Most price apps blend live listings into their ‘value’, which inflates the number above the real clearing price. A card listed at $1,200 isn't worth $1,200 until someone pays it.

Why the price apps are often wrong

Grading

Third-party authentication and condition scoring of a card (e.g. PSA 1–10), which can add or subtract value versus a raw copy.

Grading only helps when the graded-minus-raw premium beats the total cost of grading and your realistic odds of a high grade. The most expensive raw card is not automatically the best one to grade.

Gem rate

The share of submissions of a card that hit the top grade (e.g. PSA 10).

A low gem rate raises the cost of chasing the top grade and lowers grading EV. Two similar-looking Secret Rares can have very different grading maths once gem rate is applied.

Population reportpop

A grader's count of how many copies it has certified at each grade — the supply side of graded-card value.

Low population plus high demand is the real engine behind four-figure cards. On a thinly-graded card, a few inflated sales can move the comp a long way.

Why the SR Bonney price is rising

Grading EV

The probability-weighted payoff of grading a specific card after fees and sell costs — positive EV means grading is, on average, worth it.

Instead of ‘what's this card worth?’, ask ‘what's the EV of grading this copy at today's prices?’ — then act on the number. That single question is the core of what TCGIntel does.

Out of print

A set that is no longer produced, so its raw supply can only shrink — a core scarcity signal.

Out-of-print first-set Secret Rares have held value where in-print cards depreciate after rotation. Scarcity you can verify beats hype you can't.
