Yu-Gi-Oh Card Grader
Free AI grading — snap a photo of your Yu-Gi-Oh card and get an instant estimated PSA-style grade with corner, edge, surface and centering subgrades, before you pay to submit it.
Grades appear in our public grade gallery with your photo — you can remove yours in one click afterwards.
How the Yu-Gi-Oh card grader works
The grader is a pre-grading tool: it estimates the grade your card would likely receive from a professional grader — before you spend the submission fee. One photo in, a full PSA-style breakdown out, in a few seconds.
1. You upload one photo
A single straight-on photo of the card's front. The AI first detects the card in the frame, squares it up, and checks there's enough resolution to judge condition.
2. It scores the four things human graders score
Professional graders at PSA, BGS and CGC break condition into four factors — and the AI grades each one separately, exactly like a grading room does:
- Corners — each of the four corners is graded individually for wear, whitening and dings; you see a per-corner score, not just an average.
- Edges — all four edges graded individually for whitening, chipping and roughness.
- Surface — scratches, print lines, indentations, holo wear and staining across the card face.
- Centering — the border ratio measured in both directions, reported as left/right and top/bottom percentages (a perfectly centred card is 50/50; PSA's Gem Mint standard allows roughly up to 55/45 on the front).
3. It combines them the way graders do
The final 1–10 estimate isn't a simple average — a single weak factor caps the grade, just like a real submission (one soft corner can turn an otherwise-perfect card into an 8). You get the final grade, a condition label, the four subgrades, and an annotated image marking exactly where points were lost.
4. It identifies the card and does the maths
At the same time, the scanner identifies which card it is — set, number, printing — and looks up its live market value. If it recognises your card, you'll see the raw price next to the PSA 10 price, so the "is grading worth the fee?" question answers itself on the spot.
Getting the best photo
- Straight-on, with the whole card filling the frame — no angles.
- Even, diffuse light. Glare hides surface defects and holo scratches — take it out of the sleeve or toploader if you can.
- Daylight near a window beats a phone flash every time.
Accuracy & honest limits
- This is an estimate, not an official grade — the real grade depends on an in-hand inspection by the grading company.
- It grades the front of the card from your photo; back damage a photo doesn't show can lower the real-world result.
- Photo quality is the biggest accuracy factor — a sharp, glare-free shot gets a far more reliable read than a dim, angled one.
- Use it to triage: it's excellent at telling a clear 9–10 candidate from a 6, which is exactly the decision that saves (or wastes) a grading fee.
What it costs
Grading a photo uses 12 AI creditsfrom your monthly pool (it runs the full grading and identification models, our heaviest AI call). Free accounts get 30 credits a month — enough for a couple of grades — and paid plans get 300 to 3,000, with top-ups any time. You'll need to be signed in.
