Subgrades show the work behind the number
A single overall grade tells you how good a card is. Subgrades tell you why. On slabs that carry them, the overall grade is broken into the four attributes graders score, each printed with its own number, so you can see exactly which pillar held a card back or carried it. For collectors who care about the details — and the buyers who pay for them — subgrades turn an opaque number into a readable report card.
Understanding subgrades helps you judge a slab faster, spot the difference between two cards at the same overall grade, and understand why some slabs command eye-watering premiums.
What subgrades actually are
Subgrades are individual scores for each of the four condition pillars, displayed alongside the overall grade. They are most associated with BGS, which prints all four prominently, and CGC offers them as well. PSA, by contrast, gives a single number with no subgrade breakdown.
The core idea:
- Each of the four pillars gets its own number on the label
- The overall grade is derived from those four, not a simple average
- A low subgrade in one pillar can cap the overall grade even if the others are perfect
- Two cards with the same overall grade can have very different subgrade spreads
That last point is where subgrades earn their keep: they let you tell a "strong" copy of a grade from a "weak" one at a glance.
The four subgrades
The four subgrades map exactly onto the pillars every grader evaluates. Reading them in order tells you the whole condition story.
What each one covers:
- Centering: how even the borders are, front and back
- Corners: sharpness and freedom from whitening or soft points
- Edges: smoothness and freedom from chipping or whitening
- Surface: freedom from scratches, print lines, dents, and fingerprints
The Pokemon card gem mint guide covers these same four pillars in depth, and the pre-grade inspection checklist walks through inspecting each one before you submit a card.
Black label, pristine, and the top of the scale
Subgrades create their own elite tier at the very top, and the labels attached to it carry real weight with collectors.
The top designations:
- A BGS black label requires a perfect score in all four subgrades — the hardest tier to earn
- CGC pristine sits above its standard gem mint and similarly demands near-perfect subgrades
- These designations are rare precisely because every pillar must be flawless at once
- They command large premiums over the same overall number without the perfect subgrade spread
Because a black label or pristine copy is so scarce, its pricing detaches from ordinary comps at that grade. Anchor any such card against sales of the specific designation using a Pokemon card price checker and the how to compare raw and graded Pokemon card prices guide.
When subgrades actually matter
Subgrades are powerful information, but they do not change value equally for every card. Knowing when they matter saves you from overpaying for a breakdown the market does not reward.
When they move the needle:
- At the very top, where a perfect spread earns a black label or pristine premium
- When comparing two slabs at the same overall grade to pick the stronger copy
- For high-value cards where buyers scrutinize every pillar before paying up
- Less so on common or mid-grade cards, where the overall number drives the price
For choosing a grader in the first place, the Pokemon card grading company comparison and PSA vs CGC vs BGS guide weigh subgrades against turnaround, cost, and market liquidity. Track each slab's subgrades in a Pokemon collection app so you can compare copies later without re-cracking anything.
The simple rule
Subgrades break an overall grade into centering, corners, edges, and surface, turning a single number into a readable report card and creating an elite black-label or pristine tier when all four are perfect. They matter most at the top and when comparing two copies at the same grade, and less on common cards where the overall number rules. Read the four numbers, not just the headline grade, and you will judge slabs — and their prices — far more accurately than buyers who only see the big number.
