What card grades actually mean

A number on a slab looks like a measurement. It is closer to a summary — one figure standing in for four separate judgements about a physical object, made by a person, under a house style that differs between companies. Knowing what sits behind the number is most of what separates a confident buyer from a hopeful one.

The scale is shared, the standard is not

The major third-party graders — PSA, Beckett (BGS), SGC and CGC among them — all publish a scale that tops out at 10. That shared ceiling makes grades look interchangeable, and they are not. Each company maintains its own standards and its own tolerances, so the same card can come back differently depending on where it was sent. A grade is a statement by a specific grader, and it should always be read with that grader attached.

Beckett additionally reports subgrades: separate marks for centering, corners, edges and surface, alongside the overall figure. That is the clearest illustration of the point — the overall number is a reduction of four judgements, and two cards sharing a grade can have arrived there by very different routes.

The four things a grader is actually looking at

Centering is how evenly the image sits inside the borders, usually written as a ratio such as 60/40 — sixty per cent of the border margin on one side, forty on the other. It is a manufacturing property, decided at the printing plant, and no amount of careful storage will change it.

Corners and edges are where handling shows first. Softening, fraying and small dings accumulate from ordinary use and are effectively permanent. Surface covers print defects, scratches, gloss, creases and any indentation visible under angled light — the category where a card can look flawless face-on and lose grades once it is tilted.

Raw condition language, and why it is fuzzier

An ungraded card is described in words rather than numbers: Near Mint, Excellent, Very Good, Good, Poor, and combinations of them. These terms are widely used and loosely defined, and no independent party has verified them. That is not a criticism of anyone using them — it is simply what "raw" means. When we describe a raw card, we say what we can see and photograph it, and the description is our assessment rather than a grade.

When grading is worth doing

Grading costs money per card and takes time, both of which vary by company and service tier. It is worth it when authentication or condition materially changes what a card is worth or how easily it sells — and it is often not worth it otherwise. A common cards submitted in bulk can cost more to grade than the grade adds. The question is never "is this card nice?" but "does a verified grade change what this card is?"

What a grade does not tell you

A grade speaks to condition and, where the grader offers it, authenticity. It does not speak to scarcity, demand or price. Two cards with the same grade from the same set can be worth wildly different amounts, and the grade explains none of that difference. It is a condition statement, and reading it as a valuation is the most common mistake made with it.

Every card we list says which grader issued the grade, or says plainly that the card is raw and describes what we see. Where we do not hold a piece of information, we leave it out rather than estimate it.
