Grading & ROI
How to grade a card yourself
Reviewed July 2026
The short answer
You can't assign an official grade yourself — that comes from PSA, BGS, or SGC — but you can predict one closely by inspecting the same four things graders do: centering, corners, edges, and surface. Look at the card under bright, angled light, judge each factor honestly, and let the weakest one set your expectation. That pre-check is what tells you whether paying to grade is likely to pay off.
The four things graders look at
Every major grader weighs the same four attributes. A card is only as strong as its weakest one.
| Factor | What to check |
|---|---|
| Centering | How even the borders are, front and back — measured left/right and top/bottom. |
| Corners | Sharpness under magnification — even slight fraying or softness shows. |
| Edges | Chipping, whitening, or roughness along all four sides. |
| Surface | Scratches, print lines, gloss loss, dents, or stains under angled light. |
A repeatable inspection routine
Consistency matters more than a fancy setup. Do the same steps for every card.
- 1.Work over a clean, soft surface in bright, angled light.
- 2.Check centering first — tilt the card and compare opposite borders.
- 3.Inspect all four corners with a loupe or your phone's zoom.
- 4.Run your eye along each edge for whitening or nicks.
- 5.Tilt the surface against the light to catch scratches and print defects.
- 6.Let the worst factor set your grade expectation — graders don't average away a flaw.
Turn the check into a decision
The point of a self-grade isn't a number — it's a go/no-go on paying to grade. A card that's soft on any one factor probably won't reach the high grade that justifies the fee. Pair this read with the break-even math in our should-I-grade guide.
Get a second read from a photo
Self-assessment is subjective, so a second opinion helps before you commit money. Worth My Card reads centering, corners, edges, and surface from a photo and flags whether a card looks worth grading, alongside a hedged value range. Worth My Card gives an estimated value range from a card's attributes plus a condition and authenticity read — it's an educational guide, not a price database or a formal PSA/BGS/SGC grade.
Frequently asked
Can I grade my own card at home?
You can't issue an official grade — only PSA, BGS, or SGC do that — but you can closely predict one by inspecting centering, corners, edges, and surface the same way graders do.
What's the most important factor in a card's grade?
There isn't one single factor — graders weigh centering, corners, edges, and surface together, and the weakest of the four tends to cap the overall grade.
How do I know if a card is worth sending in to grade?
Do an honest self-assessment first. If any of the four factors is clearly weak, the card likely won't reach a high enough grade to cover the fee — so it's usually better left raw.
