Most people pick a grader the way they pick a coffee shop — the one they already know. That works until the card is worth more than the fee, at which point the two names start behaving very differently. PSA and CGC are not the same product at two prices. They run different ladders, they stop at different rungs, and the same card can come back reading like a triumph from one and a shrug from the other.
▸ THE QUICK VERSION
Through the middle of the scale they track each other. Both grade in half-steps from 8 to 9. CGC’s four published subgrades — centering, corners, edges, surface — were always an optional paid extra rather than the standard service, which is why a comparison chart puts CGC mid-field instead of beside Beckett. That add-on has since come off the order form, so an older CGC slab may carry four numbers where a current submission will not. PSA publishes no such breakdown at all: both weigh the card whole and return a single number.
Above a 9 they diverge. PSA has a single top rung. CGC puts three in the same space, with Pristine 10 at the top of its published scale.
Take nobody’s word on resale — including this page’s. Price your exact card in both slabs, from sold listings, before you decide the difference is worth it.
Decide by the card’s next move, not by which logo you happen to like.
Where the two ladders stop matching
THE ONE STRUCTURAL DIFFERENCE THAT MATTERS
Start with the mechanic, because nearly every argument about these two companies is really an argument about this one thing. Both grade on a one-to-ten scale, and both use half-steps through the middle of it. Send a well-loved card to either and you will get back something in the sixes, sevens or eights, and the two numbers will usually land within a half-step of each other.
The top of the ladder is where they part company. PSA has no 9.5. A card is either a 9 or it is a 10, and the entire PSA economy rests on that cliff — the whole distance between “very nice” and “gem” is one binary step. CGC puts three rungs in that same space: a Mint+ 9.5, a Gem Mint 10, and above those a Pristine 10 at the top of its published scale.
◂ SCROLL THE LADDER ▸
That geometry explains a lot of the second-hand wisdom you will hear. “CGC is stricter” and “CGC tens are easier” get argued as though they contradict each other, when they are simply describing different rungs: a Pristine 10 and a Gem Mint 10 are two different bars carrying one company’s name. Which of those bars is harder to clear than a PSA 10 is the part nobody can source — neither company publishes cross-company difficulty, so the confident version you have read is somebody’s impression wearing a fact’s clothes. If you compare a top CGC label against a PSA 10 and conclude the market is irrational, you are usually comparing two rungs that were never the same height.
Criteria and label formats change. Before a serious submission, read the grader’s own current published scale rather than a forum post you half-remember — the wording, and sometimes the top grades themselves, get revised.
How to price the resale gap yourself
CHECK IT, DO NOT ASSUME IT
Every comparison you will read makes a confident claim about which slab sells for more, and almost none of them attach a source. Treat all of them as unverified, including the version you already believe. Neither company publishes resale figures, and the gap — whichever way it runs on your card — moves by set, by era, by grade and by month.
So price it per card. Pull sold listings, never asking prices, for your exact card: same set, same card number, same parallel, in both slabs, at the grade you realistically expect rather than the one you are hoping for. Then subtract from each side the fee for the tier you would actually use, shipping in both directions, and insurance. What is left is the only premium that applies to you, and finding it takes about ten minutes.
If the comparables are thin — one sale in each slab, months apart — that is an answer too. A card with no liquid market in either holder is a card whose grade will not be tested any time soon, which argues for spending less to get it.
You are not choosing a grader. You are choosing whose opinion the next buyer will accept without arguing.
ONE GRADE NAME, TWO HOUSES — PSA ABBREVIATES IT ON THE FLIP, CGC SPELLS IT OUT. THE NUMBER MATCHES; THE BAR BEHIND IT DOES NOT.
Choose by the card’s next move
THE DECISION, IN ONE FORK
Here is the question that actually settles it, and it has nothing to do with grading at all: what happens to this card after it comes back?
◂ SCROLL THE FORK ▸
There is a fourth case worth naming: the card that is almost certainly not a 10. If your honest read is that centering or one soft corner will cap it around an 8, the premium label stops mattering, because at that level buyers pay for the number far more than the logo. That is a card for the cheaper quote — or more often not a grading candidate at all, a question worth settling at should you grade it before you spend anything.
▸ BEYOND THE GRADE ITSELF
Five differences you will actually feel.
◂ SCROLL THE COUNT ▸
None of them decides the question — they decide what the answer costs you. Read the five as a price list, not a verdict: each changes what the submission costs in money, time or patience; none changes which company the next buyer trusts.
IF YOU REMEMBER NOTHING ELSE
The read, in one line
Slab it — in whichever holder your sold comps reward — when someone else’s confidence has to survive a listing page. Take the cheaper quote when the confidence only has to satisfy you.
And when you cannot say which — when the card sits genuinely balanced between “I’d sell that” and “I’d never sell that” — the correct move is to leave it raw a while longer. A raw card can still become either. A slabbed one has already chosen.
Once you have picked a lane, the next skill is reading what comes back. Learn to read a population report without lying to yourself and you will stop being surprised by your own grades.
