Comparison
GradeX vs BGS
GradeX predicts BGS grades — including subgrades and the Black Label 10 odds — before you commit to Beckett's slabbing fee. BGS issues the official sealed slab.
At a glance
BGS (Beckett Grading Services) is best known for its four-subgrade system — centering, corners, edges, and surface — and the rare Pristine 10 "Black Label," which requires all four subgrades to be 10. Beckett slabs are most common in the modern era for premium cards where collectors specifically value subgrade transparency.

When to choose GradeX
- Subgrade-conscious sellers who want to know their corners / edges / surface scores before submitting.
- High-volume slab buying — confirm the slab matches the photos before paying.
- Cards where centering is borderline and getting the user's measurement matters more than the grader's eyeball.
When to choose BGS
- Cards with strong Black Label 10 potential — the slab itself is part of the resale premium.
- Vintage and mid-century cards where subgrade transparency justifies BGS over PSA.
- Premium / autograph cards where the BGS subgrade label commands a buyer-side discount on uncertainty.
The short verdict
Run GradeX first. If the predicted subgrades suggest a strong shot at a Black Label 10 or BGS 9.5+, submit. If the predicted overall is a 9.0 or lower, the slabbing premium may not justify the fee — sell raw or use the marketplace and skip BGS.
Quick answers
Does GradeX predict BGS subgrades?▾
Yes. Every scan returns predicted subgrades for centering, corners, edges, and surface — the same four BGS uses. The overall is calculated using BGS's published weighted-average rule.
Can GradeX tell me if a card might Black Label 10?▾
Indirectly — when all four predicted subgrades come in at 10, you've got Black Label potential. The exact official outcome is at Beckett's discretion (sometimes a 9.5 corner sneaks through that you couldn't see in the photo), but the prediction is a strong indicator.
Why do GradeX's centering numbers sometimes differ from BGS's?▾
Centering is measured manually in GradeX — the user drops eight lines on the card themselves. BGS measures with a physical ruler against the slab. Small differences (≤ 5%) are within tolerance; larger differences are usually due to capture-angle distortion that the user can correct via the leveling slider in the wizard.
