One Piece Graded Cards: PSA Populations, Gem Rates & Premiums (August 2026)

Live PSA and BGS population data for the One Piece Card Game: 904,433 PSA slabs, an 87.3% PSA 10 rate, +11.5% growth in 30 days, and what grading is worth.

The One Piece Card Game has 904,433 cards in PSA holders and 210,261 in BGS holders, across the 3,041 English cards Cardlogs tracks population for. According to Cardlogs population data, 87.3% of every graded One Piece card comes back a PSA 10, and the population grew 11.5% in the 30 days to August 4, 2026 — roughly 69,000 new slabs in a month.

How many One Piece cards have been graded?

1,174,161 in total across PSA, BGS, CGC and SGC, as of August 4, 2026. The split:

PSA holds 77.0% of the graded One Piece market. BGS takes 17.9% and earns it at the top end, where the four-subgrade-10 Black Label is the only slab in the hobby that reliably prices above a PSA 10.

As of August 4, 2026 the five most valuable One Piece PSA 10s are Monkey.D.Luffy - ST01-001 (Serial Number) at $61,851.66, Monkey.D.Luffy (118) (Red Super Alternate Art) at $36,454.37, Gol.D.Roger (Manga) at $19,175.13, Monkey.D.Luffy (SP) from Anime 25th Collection at $18,457.64 and Monkey.D.Luffy (PRB02-005) at $18,000. All five hold at least 45 PSA 10s and all five carry a raw price that passes our cross-venue screen.

That million-slab total is the number worth sitting with. Under four years after the game launched, One Piece has produced more graded cards than most trading card games ever will:

All four rows run the same de-duplication and the same English-only filter described in the methodology, so they are directly comparable — a change from our Riftbound population report, which compared a deduplicated Riftbound figure against three raw ones. One Piece's PSA population is 45.7 times Riftbound's and 5.8% of vintage Pokemon's.

What is the PSA 10 gem rate for One Piece cards?

87.3%, and the honest headline is how little it varies. Cardlogs computes the gem rate as PSA 10s divided by that card's total PSA population — the share of submissions that came back perfect.

Across mainline booster expansions with more than 15,000 slabs, every set lands between 83% and 91%:

Age explains almost none of it. Romance Dawn, the launch set from December 2022, gems at 87.5% — better than Carrying on His Will from November 2025. The best-grading set in the game is Wings of the Captain from spring 2024, and the worst is Pillars of Strength from summer 2023, nine months apart in the release calendar and 7.2 points apart in gem rate. Whatever moves this number, it is a print-run property, not a shelf-life one.

Distribution moves it a little. Splitting the whole corpus by how the card reached a collector:

A 1.4-point gap, in the direction you would expect — a card handed out loose at an event has been through a tournament bag before it reaches a grader. It is a much smaller effect than the same split in Riftbound, where launch-window prize-pack promos ran six points below the newest sealed set. One Piece promos are handled better, or graded more selectively, or both.

The number that actually stands out is the cross-game one. On the same de-duplicated basis, vintage Pokemon returns a 34.7% PSA 10 rate against One Piece's 87.3%. A One Piece card sent to PSA comes back a 10 about seven times in eight; a vintage Pokemon card does it about one time in three. That is the whole modern-versus-vintage grading argument in two numbers, and it is why "pop 500 PSA 10" means something very different in each game.

Which One Piece cards have the highest PSA populations?

Monkey.D.Luffy (055) (College Basketball US Voyage), the P-055 promo, at 26,800 PSA submissions — more slabs than the entire Riftbound game has produced.

Nine of the twelve are Luffy. Eight of the twelve are promos rather than pack-pulled cards. The graded market for One Piece is not a market for the game's best cards — it is a market for its most distributed collectibles, and the two lists overlap far less than you would guess from a price chart.

Two of the top twelve are worth calling out individually. The PSA Magazine Luffy at 8,502 submissions is a promo distributed by the grading company itself, which is about as clean a demonstration of induced supply as this hobby offers. And Monkey.D.Luffy (Convention Promo 2024) gems at 76.2%, the worst rate in the top twelve — nearly a quarter of the 6,425 people who sent one in got back a 9 or lower.

One card in the raw top twelve is excluded from the table above. Monkey.D.Luffy (OP07-109) in Special Tournament Promos carries 5,872 PSA slabs, but its $4,099.50 TCGplayer price fails our cross-venue screen in both directions — Cardmarket reads 1.54x and the eBay sold median 0.49x. When three venues disagree that badly, no single number is publishable.

How fast is the One Piece graded population growing?

+11.5% in 30 days, on a fixed cohort of 784 cards. Measuring this correctly is not optional: a naive sum of nightly populations moves with how many cards were sampled that night, which invents trends in both directions.

Our own data shows the trap clearly. The raw nightly sum reads 1,389,012 on July 5 and 1,622,552 on August 4 — apparently +16.8%. But the July 5 sum covers 3,343 sampled cards and the August 4 sum only 1,658. Half the sample, a bigger number, and a growth rate 5 points too high. Every figure below instead counts only cards with a reading on both endpoint dates.

According to Cardlogs population data, roughly 19,000 One Piece cards entered PSA holders in the single week to August 4, 2026. The PSA 10 count grew at almost exactly the same rate as the total (+11.3% vs +11.5% over 30 days), so the gem rate is holding as volume scales — 87.3% at the start of the window, 87.2% at the end.

Set that against Riftbound's +33.7% over its own 30-day window and the difference between a young graded market and an established one is visible in one number. Riftbound is growing three times as fast off a base 46 times smaller. One Piece's population is compounding, not exploding, which is what a market past its first grading rush looks like.

Is it worth grading a One Piece card?

Median 3.16x the raw price on the 42 cards where the premium can be attributed cleanly, out of 3,041 in the report. The screen behind that number is strict and is explained in the next section.

That is the top twelve of 42. Median 3.16x, mean 3.46x, range 0.90x to 8.01x, and exactly one of the 42 trades below its raw price — Gecko Moria - OP14-104 (Alternate Art), where a $30.58 PSA 10 sits under a $33.99 raw card.

Scarcity does not drive the premium, exactly as we found in Riftbound. Sorting the same 42 cards by how many PSA 10s exist:

The scarcest bucket carries the lowest median but one. A pop-under-100 One Piece card is usually not a card that is hard to gem — it is a card too cheap or too obscure for anyone to have bothered submitting. Low population signals low demand at least as often as it signals scarcity, which matters if you are paying up for a "pop 40" slab and expecting the number to do the work.

The practical read: at roughly $20-30 all-in per card for grading and shipping, a 3.16x median only clears its cost on cards already worth about $30-40 raw. Below that, an 87% chance of a 10 is not the question — the fee is. And note where the multiples cluster: alternate arts and event promos in the $30-$180 range, not the four-figure chase cards, whose raw prices already embed most of the condition premium. Eight of the 42 come from Adventure on KAMI's Island alone, the game's current submission wave.

Why we won't quote a premium for most One Piece cards

2,999 of the 3,041 cards in this report are excluded from the premium table. The buckets, in the order the screen applies them:

The third bucket is the One Piece-specific one, and it is worse here than in any game we have measured. One Piece prints the same card number many ways — a base common, an alternate art, a manga art, an SP, a gold SP, a tournament-winner version — and graders do not always separate them in a population report. 2,185 of the 2,776 English card numbers in our One Piece catalog carry more than one printing, and 2,750 rows in this report, 90% of the corpus, share a card number with a printing priced more than 1.5x away.

"By more than 1.5x" understates it badly:

Separately, 98 population records in our feed are each attached to two or more different One Piece printings — one graded population covering cards that trade at wildly different prices.

A card still qualifies despite having cheaper siblings when GemRate resolved its population to that exact printing, which our pipeline records as a per-printing population identifier. That is the line we draw, and it is a judgement call worth showing rather than burying. A maximally strict version — disqualify any card whose number has any differently-priced printing, resolved population or not — leaves 4 cards out of 3,041, which is not a measurement, it is a refusal to measure. The rule we publish keeps 42.

The consequence is still uncomfortable and worth stating plainly: every one of the twelve most-graded cards in this article is excluded from the premium table. The cards the world submits most are precisely the cards whose card number also covers a bulk common, so their raw price and their slab price cannot be safely divided. Any One Piece graded multiple you see quoted without this screen — including ones we could have quoted — is at risk of comparing a slab of one printing against the raw price of another.

We publish the screen rather than the number it removes. It is the same discipline behind the corroboration rule in the monthly One Piece market watch, where a $35,101 serialized Zoro ask is excluded from the ranked table for exactly the same class of reason.

Where this data comes from

Cardlogs aggregates prices nightly from TCGplayer, Cardmarket and eBay sold listings (via PriceCharting) across 11,573 tracked One Piece cards, plus PSA and BGS population data from GemRate and graded market prices covering PSA, BGS, CGC, SGC and TAG.

Population coverage is partial by design. 3,774 of those 11,573 rows carry a population record, which becomes 3,041 unique English graded entities after de-duplication. Of those, 786 have a raw market price of $30 or more and 2,255 are under it — so this is not a chase-card-only sample, but it does under-cover bulk commons, which are graded rarely and priced in cents.

Three screens run before any number above is published:

1. De-duplication. One graded population record can be attached to several rows in our card table, so a raw SUM double-counts. Rows are collapsed on their GemRate identifier, falling back to the TCGplayer product ID, and non-English rows are excluded: 3,774 rows become 3,041 unique English entities. Every population total in this article is the de-duplicated figure, including the cross-game table.
2. Fixed-cohort growth. Population change is measured only across cards with readings on both endpoint dates, so a night that sampled fewer cards cannot masquerade as a decline — or, as here, a night that sampled fewer bigger cards cannot inflate the growth rate.
3. Cross-venue corroboration. A raw price is only quoted when Cardmarket (converted at the day's ECB rate, $1 = €0.86843) or the eBay sold median lands within 30% of the TCGplayer price.
4. Sibling-print attribution. A graded premium is only quoted when the raw price and the slab plausibly describe the same object: no second printing of that card number carries its own population record at a materially different price, no population record is shared between differently-priced printings, and where a cheaper sibling exists without population data, the card's own population must be resolved by GemRate to that specific printing. 2,750 of 3,041 cards fail this.

Population figures are as of August 4, 2026; prices as of August 5, 2026. Graded prices come from a single source and cannot be cross-checked the way raw prices can — treat a graded price with a small population behind it as an estimate, not a quote.

What to watch next

Three things move this report over the next quarter. The next One Piece expansion will test whether the 83-91% band holds for a set graded from release rather than retroactively. The Adventure on KAMI's Island alternate arts — four of the twelve biggest premiums in this article — are the current submission wave, and their multiples will compress as their populations fill in. And the Black Label count is the one figure here that behaves like real scarcity: 8,852 across three and a half years of a million-slab market.

If you are grading One Piece today, the conclusion is unglamorous. The gem rate is high enough that grading is barely a gamble, the populations are large enough that they are not doing the work your price assumes, and on anything under about $40 raw the fee eats the premium. The interesting money is in the $30-180 alternate arts, not in the cards everyone already slabs.

You can track raw, graded and sealed One Piece prices side by side — TCGplayer, Cardmarket and eBay sold, with PSA and BGS populations on every card page — on Cardlogs, on the web and on iOS and Android.
