How to Grade Your Own Card's Condition (NM, LP, MP, HP)
Condition is the single biggest lever on a card's price after identity. The same card can trade at full market value or a fifth of it depending on four things a grader looks at — and you can check all four yourself in about a minute, with nothing but good light. Doing it honestly is what makes the grading decision and every valuation downstream of it worth anything.
The four things graders actually look at
Every grading company weighs the same four attributes, whatever their scale:
- Corners — sharp and square, or soft, rounded, frayed?
- Edges — clean, or showing white flecks, nicks or roughness?
- Surface — free of scratches, print lines, dents, clouding and fingerprints?
- Centring — are the borders even, front and back?
Corners and edges are where most cards lose their grade, and both are damage from handling rather than manufacturing. Centring is the opposite: it's decided at the printer and there is nothing you can do about it.
How to actually inspect a card
Use a bright, indirect light and hold the card at an angle so the light rakes across the surface rather than reflecting straight back — that's how you find scratches and print lines that vanish under flat lighting. Check the back as well as the front; a flawless front with a scuffed back is still a damaged card. A jeweller's loupe or a phone camera at maximum zoom is enough magnification. Handle by the edges, and do this over a soft surface.
The condition tiers, honestly applied
- Near Mint (NM) — looks essentially new. Sharp corners, clean edges, no visible surface wear. At most one very minor flaw you have to hunt for. This is the condition most price guides quote by default.
- Lightly Played (LP) — minor wear visible on close inspection: slight edge whitening, a touch of corner softness, perhaps a light surface scratch. Still displays well. Typically 70–85% of NM.
- Moderately Played (MP) — obvious wear at a glance: noticeable whitening, rounded corners, scratches or minor creasing. Roughly 45–65% of NM.
- Heavily Played (HP) — significant damage: heavy whitening, creases, dents, possible water marks. Often 20–35% of NM.
- Damaged — tears, holes, writing, major creasing. Priced for the artwork, not the card.
Those percentages are rules of thumb, not rules. The gap between conditions widens as cards get more expensive and more sought-after — on a chase card the NM-to-LP step alone can be hundreds of dollars, while on a bulk common it's a few cents.
Be harsher than you want to be
The most common and most expensive mistake is grading your own card optimistically. Two habits help. First, assume the flaw you can almost see is one a buyer will definitely see. Second, grade the card as if you were buying it from a stranger — the standard you'd apply to someone else's listing is usually the right one.
This matters twice over. Overstating condition when selling produces returns and "not as described" disputes that cost more than the honest price would have. Overstating it before paying for certification is how people end up with a PSA 8 they expected to be a 10.
What condition can't tell you
A self-assessment is not a grade. Professional grading also authenticates the card and produces a number the market trusts — which is exactly why slabs command a premium over raw cards in the same condition. Your own assessment tells you what the card is worth today, raw, and whether certification is worth attempting. It doesn't substitute for the slab.
Putting a number on it
SplitShot prices from a Near Mint baseline and applies a condition model, so you can see what your actual copy is worth rather than the idealised one in a price guide. Assess the card honestly first, then look it up — and if it's clean enough to be worth certifying, the grading maths takes it from there. For anything you're storing rather than selling, proper storage is what stops an NM card quietly becoming an LP one.
