Know the grade before you pay to submit.
From phone photos, Gradeon estimates the grade PSA, BGS or CGC would most likely give your card. See every defect, check the centering and track what your collection is worth.
How a pre-grade is built
- 01 · Capture
Photograph the front and the back
Two phone photos are enough. Add close-ups of a corner or an edge and Gradeon inspects those too.
- 02 · Centering
Measure the borders
Gradeon finds the card edge and the printed border on every side, then you confirm the eight pins with one tap.
- 03 · Defects
Draw every defect on the photo
Eleven defect types, each with a severity from 1 to 5. Glare, holo patterns and factory cuts are not defects.
- 04 · Sub-grades
Score four areas, front and back
Surface counts 35 %, corners and edges 25 % each, centering 15 %. No side sits more than one point above its weakest area.
- 05 · Pre-grade
One grade on the scale you know
A PSA-comparable pre-grade from 1 to 10 in half steps: the grade a professional would most likely give, before you pay to submit.
Pre-grades are AI estimates, not official PSA, BGS or CGC grades. Illustrated card; numbers from a worked example.
1–10 in half steps, 4 sub-grades, Front and back, 11 defect types, Severity 1–5, Centering checked by you, Standard ~1–2 min, Deep Analysis, Rapid Scan, Pokémon · One Piece · Riftbound
The heaviest area: scratches, creases, print lines and dents live here.
Each one drawn on your photo, with a severity from 1 to 5.
Grades run from 1 to 10 in half points, like BGS and CGC.
Every week, refreshed automatically, on iOS and Android.
