Add your collection

Get every slab in, in minutes

However your collection lives today — in a box, a spreadsheet, or an eBay account — Slabline has a fast way in. Add by cert, scan the label, batch-scan a stack, or import in bulk.

By cert number

Type or paste a PSA, BGS, SGC, or CGC cert and Slabline pulls the card details, current value, and price history automatically.

Photo / AI scan

Snap the slab label and Slabline reads the grader, cert, and grade for you — no typing.

Continuous slab scanning

Point your phone at a stack and scan the PSA/BGS/CGC/TAG QR codes one after another — add a whole box in minutes.

CSV & eBay import

Bring an existing spreadsheet, or connect eBay to import your graded listings and purchases in one pass.

Why cert-first matters

Adding by certification number ties each card to its exact graded identity — so the valuation is matched to that cert and grade, the provenance is verified, and your insurance schedule is claim-ready from the start. No manual data entry, no guesswork.
