Slabscope

Tells you what to do with it.

Three things nobody else does.

PSA fees start at $32.99. Slabscope helps you decide which cards are actually worth that — before you pay.

Cross-grader EV

Ranks all six graders by predicted grade × actual market premium × actual fee tier. PSA isn't always the right answer. Nobody else tells you this.

Forensic sub-grades

Per-corner, per-edge, centering ratios, defect map. Same four criteria PSA uses, scored honestly. Bad photos cap at PSA 8 by design.

Front + back, both sides

Most pre-graders skip the back. Half of PSA's centering tolerance is back-side. Grading both is how you stop the surprise PSA 8 on a 'PSA 10 candidate.'
