Graded cards
Quest works with your graded cards.
Slabs from every major grader belong in your collection alongside your raw cards. Quest records who graded each one and the grade it carries, and points you to each grader's own tools when you want to verify a slab.
What Quest records for a slab
Photograph a slab with its label in view and Quest reads the grader and the grade from the label. You check the read, the same as any card.
Quest knows the labels of PSA, Beckett (BGS, BVG and BCCG), SGC, CGC, CSG, Arena Club, TAG, ISA, GMA, MNT, KSA, Ace, Rare Edition and Edge. A slab from a grader not on that list is still recorded as a graded card, never as raw.
Checking a certification number
Lexi, Quest's collecting agent, can check a PSA, Beckett (BGS), SGC or CGC certification number and confirm which card it belongs to. It confirms identity only. It isn't a population report. For the other graders, use the grader's own verification, below. See Lexi.
