PSA vs. CGC vs. BGS: What the Grade Ladders Actually Show

PSA, CGC, and BGS aren’t three views of the same underlying number — they’re three separate markets. A PSA 9 and a CGC 9 of the same card aren’t interchangeable just because the number matches; each grading company has its own reputation, its own submission volume, and its own pool of buyers who specifically shop for that company’s label. Treating “graded” as one undifferentiated tier — as if a 9 is a 9 regardless of who put it in the slab — is one of the fastest ways to misprice a card.

Our own graded data reflects that split directly rather than papering over it. Every card we track keeps a separate ladder per grading company, and a card’s page only ever shows a company tab when we actually have graded sales data for that company on that card — there’s no synthetic “BGS estimate” backfilled from PSA numbers when BGS data is thin or absent. If a card’s ladder shows only PSA and CGC, that’s an honest reflection of where the graded sales volume actually is for that card, not a gap we’ve chosen to hide.

That distinction matters most right at the top of the market, where the gap between grading companies tends to widen rather than narrow. A raw card and a played card are close enough in most buyers’ minds that the grading-company label barely registers. A Gem Mint graded copy is a different story — at that end of the ladder, buyers are shopping for a specific company’s reputation as much as the number on the label, and the three companies’ numbers for the same card can genuinely diverge.

None of that is a knock on any one company’s grading standards — it’s just a description of how a market with three competing certifiers actually behaves. Buyers develop preferences, communities form around specific labels, and those preferences show up in price whether or not the underlying physical grade is comparable. Reading a ladder well means treating each company’s numbers as its own data series worth checking on its own terms, not as three slightly different measurements of one true value.

It’s worth being specific about where these numbers come from, because it’s a meaningfully different pipeline than the raw market price shown everywhere else on this site. Raw prices come from TCGplayer’s own market-price figure, pulled once a day. Graded values are sourced from an entirely separate feed of graded-market sales data, refreshed on the same daily cadence but through its own pipeline — the two numbers are never derived from each other.

Each grade in the ladder is priced independently, computed as a rolling average of recent sales for that specific grade — not interpolated from the grade above or below it, and not scaled off the raw price by a fixed multiplier. A PSA 10 and a PSA 9 of the same card each have their own trailing sales window backing their number; if PSA 10 sales for a card have been thin recently, that grade’s price reflects that directly rather than being smoothed against the more liquid grades around it.

The ladder also refreshes at the card level, once a day, alongside the raw price walk — so a ladder you check today reflects sales data from within the last day, not a stale snapshot from whenever the card was first added to the catalog. None of this makes the numbers “real-time” in the sense of updating tick by tick — grading-market sales simply don’t happen at that frequency for most cards — but it does mean the ladder tracks the market’s actual direction rather than a fixed reference price set once and left alone.

Each individual grade line also carries two figures internally — a 7-day rolling average and a 30-day rolling average, both sourced from the same graded-market feed — and our tools default to the 7-day figure when that window actually has sales behind it, falling back to the 30-day figure when it doesn’t. That’s a small design choice with a real effect: a grade with an active, currently trading market shows you a genuinely fresh number, while a thinly traded grade quietly leans on a longer history instead of going blank or reporting a number built from a single recent outlier sale.

Once you have a real per-grade ladder in front of you instead of a single “graded price,” the most useful thing to look at is its shape, not just its top. A ladder that climbs smoothly from grade to grade tells a different story than one with a sharp jump concentrated at the very top — and for a genuine chase card, the second pattern is far more common than the first. The step from a strong 9 to a Gem Mint 10 tends to be the steepest single jump in the whole ladder, disproportionate to every step below it, because Gem Mint copies of a hot chase card are simply scarcer than the demand for them.

That top step is also where prices move the fastest and the sample sizes get thinnest, which is exactly the combination that produces volatility. A handful of Gem Mint sales in a short window can swing a grade 10 line meaningfully in either direction in a way a deeper, more liquid grade like a 7 or 8 almost never does. That’s not a flaw in how the ladder is built — thin sales data is an honest reflection of a thin market — but it’s a reason to treat the top-line number on a rare card as a current read, not a fixed value, especially right after a set’s release when very few copies have been graded at all.

Serious grading-market research often layers a population report on top of a price ladder — a count of how many copies each company has certified at each grade for a given card, published by the grading companies themselves. A thin population at the top grade is one of the strongest possible explanations for why that grade’s price sits far above the grade beneath it, and it’s a genuinely useful cross-check against the ladder shape described above.

Population and price aren’t the same signal, though, and it’s worth keeping them separate even when you have both in front of you. A grade with a small certified population but almost no recent sales activity can still show a stale or missing price line simply because too little has traded recently to compute one — a thin population doesn’t automatically mean a thin, active market at that grade, just a thin certified count. The two numbers answer related but genuinely different questions, and conflating them is an easy way to over-read a population report as a price signal it was never built to be.

It’s worth being direct about a limit here rather than implying more than we actually track: population counts aren’t part of our own graded-market data, which is built from recent sales activity, not certification totals. A ladder here tells you what a grade has actually been trading for recently; it doesn’t tell you how many total copies exist at that grade across the card’s whole certification history. If you want that second number specifically, each grading company publishes its own population report, and it’s a genuinely useful companion to the price data here rather than a replacement for it — the two answer different questions about the same card.

Beyond the raw numbers, the three companies aren’t interchangeable processes wearing different labels. PSA has the deepest brand recognition in the Pokémon market specifically — a PSA-graded card is generally the easiest of the three to sell to a broad buyer pool sight-unseen, and that liquidity is a real part of what its price reflects, separate from the physical grade itself. CGC has built a strong following of its own, particularly for buyers who care about its packaging and presentation, and its submission volume has grown enough in recent years that a thin CGC ladder on an older card is often just a function of when the card was submitted, not a signal about the company.

BGS is structurally the odd one out among the three: it grades on four separate subgrades — centering, corners, edges, and surface — rather than issuing a single number from a single pass, and a card that hits a perfect subgrade across the board earns BGS’s distinct “Black Label” 10, a tier the other two companies don’t have an equivalent for. That’s a genuinely different grading methodology, not just a different label — two cards that would both plausibly grade a PSA 10 can land at different overall BGS numbers depending on how their four subgrades individually shake out.

None of that makes one company objectively “better” than another — it makes them different products serving overlapping but distinct parts of the same market. Which one is worth chasing for a specific card comes down to where that card’s buyers actually shop, which is exactly the kind of thing a card-specific ladder can show you and a single generic “grading is worth X%” rule of thumb can’t.

Turnaround and submission volume differ between the three companies too, and those differences shift over time as each company’s own backlog grows or shrinks — a company that’s comparatively fast this year can be the slower option next year if submission volume spikes industry-wide. That’s a separate axis from price entirely, but it’s worth factoring in alongside the ladder if you’re deciding where to send a card rather than just researching one you already own — see our grading submission walkthrough for how that decision fits into the rest of the process.

It’s worth explaining plainly why a card’s ladder sometimes shows all three companies and sometimes shows only one, because it’s not random and it’s not a data gap on our end. A grader tab only appears when there’s enough recent graded-sales volume for that specific company on that specific card to compute a real number from — no tab gets fabricated to make a ladder look more complete than the underlying sales data actually supports.

That means the shape of which graders show up is itself a signal. An older, widely-collected card that’s been submitted to every major service for years is far more likely to carry a full three-company ladder than a card that’s only weeks old, where PSA submissions might already be trickling back while CGC and BGS turnaround on the same copies simply hasn’t caught up yet. A freshly released chase card showing only one grader isn’t necessarily less “gradeable” than an older one with three — it may just be earlier in its own submission cycle, and worth checking again in a few weeks as more graded copies work their way back to sellers.

Card-specific popularity plays a role too, separate from age. A card with a broad following draws submissions to every major service almost as a matter of course; a lower-profile card from the same set can sit for years with graded sales concentrated at just one company, simply because that’s where the small pool of collectors who care about that specific card happen to submit. A missing grader tab isn’t a verdict on the card’s quality — it’s a reflection of submission behavior, which is its own kind of market signal worth reading rather than a data hole to be suspicious of.

A detail that’s easy to miss: when a card has more than one mapped printing — a standard version and a print-error variant, for instance, or a normal print alongside a reverse-holo — each printing carries its own graded ladder, not a single shared one. A PSA 10 of the common print and a PSA 10 of a scarcer variant of the exact same card can trade at meaningfully different prices, because graders and buyers treat them as genuinely separate products, not different photos of the same slab.

That’s the same logic the raw-price side of this site already uses for variant printings — see our printings and variants guide for the fuller picture — carried through consistently to the graded side. If a card you’re researching has more than one printing listed, checking the ladder for the specific printing you actually own (or are considering buying) matters more than checking the card’s “default” printing and assuming the numbers transfer.

The practical takeaway from all of this is fairly simple: don’t shop for a graded card off a single remembered number. Check the specific company, the specific grade, and — if the card has more than one printing — the specific printing, on the card’s own page, before deciding whether an asking price is fair. A number that was accurate last month can be stale today, especially near the top of the ladder where sales volume is thinnest and prices move fastest.

If you’re weighing whether to submit a raw card for grading in the first place rather than shopping for an already-graded one, the ladder is also the right starting point for that decision — our grading calculator pulls a card’s real ladder automatically and compares it against submission costs, and our is grading worth it guide walks through the broader decision beyond just the math. Either way, the ladder itself — checked per card, per company, per grade — is a better guide than any general rule about what grading “usually” adds.

The single habit worth carrying away from all of this: a “graded price” is never one number. It’s a company, a grade, a printing, and a moment in time, all four at once — and the further any of those four gets from what you actually have in hand, the less that remembered number tells you. Check the real ladder, for the real company, on the real printing, before you buy, sell, or submit.
