Slab measures your cards with computer vision against PSA, CGC, and TAG criteria — so you only pay grading fees for the cards that earn them.
Guided camera captures front and back with live lighting and framing checks — so the analysis starts from a photo worth analyzing.
Computer vision measures centering from the physical card boundary. AI inspects corners, edges, surface, and print quality — the criteria professional graders use.
Submit, Borderline, or Pass — with a full breakdown of every check, so you know exactly what to send in and why.
Front and back L/R and T/B ratios measured from the physical card boundary with computer vision. Certified results shown; uncertified axes shown as "—" rather than a guess.
All four corners on both sides inspected for chipping, fraying, and whitening — the most common reason a card falls short of a top grade.
Hard to spot under normal light. Slab is tuned to catch subtle edge whitening that will register with a grader.
Front and back scanned for scratches, scuffs, and print loss. Holo and reverse-holo surfaces get dedicated logic for their light-reactive nature.
Print lines, ink spots, and factory marks — distinguished from surface damage. Not every flaw is your fault, and Slab knows the difference.
Back centering, whitening, and surface damage flagged individually — because graders check both sides, and so do we.
Slab's centering measurements are validated per card class against professionally graded reference data, and we publish the accuracy figures — designed around documented PSA 10 standards, not arbitrary pass/fail.
Raw and PSA 10 market prices on every card in your collection, plus weekly market movers across all four games — so the grading-fee math is in front of you before you commit.
Run the expected-value check: if the graded price doesn't clear the fee, Slab shows you before you spend it.
Every scan ends in a clear call. "Pass" means the card doesn't earn the grading fee — keeping your money is a win too.
The checks clear. This card has a real shot at the grade that makes the fee worth it.
Close on one or more checks. Slab shows you exactly which ones, so you can decide with open eyes.
The flaws will cost you the grade. Skip the submission, save the money — and know why.
