Expected hits per product: 0.97 (counting every tier the pull-rate table enumerates). A One Piece pack is 12 cards: on average about 1.0 is one of the cards above, and the other ~11 are commons, uncommons and rares worth about a cent. (These odds describe that one notable card, so they don't sum to 100%.)

What are the odds you profit?

Same assumptions as the EV: odds are uniform within each tier (real sets short-print their biggest chases, so true odds are usually a touch worse than this), cards sell at today's market price, and selling costs nothing. Read it as a ceiling, not a promise.

Each tile: card value (top-right), then the odds of pulling that exact cardfrom a single pack — shown as “1 in N packs” and as a percentage (the same number, two ways). Per-card odds assume every card in a tier is equally likely — no public data quantifies short prints. See methodology.

Koala #OP12-086
Special (SP)

Premium special-art printings — showcase/borderless prints, ultra-secret SARs and the like. They’re the set’s headline chases but pulled far below any rate public data quantifies, so they’re shown here for reference and deliberately excluded from the EV above.

Is it worth grading?

PSA US fees, approx · Jul 2026

What a PSA 10 sells for vs the raw price plus PSA's fee — the upside if the card grades a 10. The odds of actually getting a 10 are a separate column, still pending.

Net if 10= PSA 10 value − raw − fee, the gain assuming a perfect grade (an upper bound — most cards won't 10). Chance of 10is this card's own PSA population — of every copy graded, the share that came back a 10 — and it drives the graded EV toggle instead of one flat assumption. Read it as a ceiling, not a coin flip: it counts cards people CHOSE to submit, which skews toward good copies, and a card pulled from a pack today may fare worse. A “—” means too few graded copies to quote. PSA 10 prices come from Scrydex and PokemonPriceTracker. Fees exclude shipping and use the cheapest PSA tier for each card's declared (graded) value. PSA paused its cheaper Value tiers in June 2026 under a grading backlog, so Regular ($79.99) is the current floor — grading a card much under ~$100 rarely makes sense.

How many packs for…

770 packs for a 50% chance
2,558 packs for a 90% chance

No number of packs guarantees it — that is what a -44.7% market ROI pays for.

Pull-rate data

LOWn undisclosedsource ↗

Community-aggregated advertised pull rates for a standard 24-pack One Piece booster box, from TCGTalk's box-pull-rate guide (2026): Leader ~1 per 2 packs (~12/box), Super Rare ~1 per 3 packs (~8/box), Parallel/Alternate Art ~2/box (~1 per 12 packs), Secret Rare ~1/box (~1 per 24 packs), Manga Rare ~1 per 2-6 cases (~1 in 576-1,728 packs). Bandai does not publish official odds, and this source discloses no sample size, so this table is capped at LOW confidence by design. The uniform-within-tier assumption is especially rough for One Piece: the Alternate Art tier spans sub-$5 commons to $100+ chase cards, so per-card odds within a tier are indicative only. Prices blend Scrydex (TCGplayer market) and PriceCharting (eBay-sold); cards without a matched price are excluded from their tier average, never counted as $0. The Special (SP) tier is deliberately NOT modelled in EV: SP cards are priced by a single source (TCGplayer market via Scrydex) with no second source to cross-check, and thin-market figures proved unreliable, so counting them would distort box EV. They remain in the catalog.

  • ! No priced cards for rarity "treasure_rare" — its EV contribution is counted as zero.
