What provenance covers

For graded cards, provenance means a verifiable grading cert, the grading pedigree, and records of how and when you acquired the card. It answers the questions a future buyer, or an insurer, will ask.

Why it protects value

Documented cards are easier to authenticate, easier to sell, and easier to claim on after a loss. Thin documentation introduces doubt — and doubt costs money at sale and at claim time.

Build the record

Slabline scores provenance as one of its five factors (10% of the Slabline Score), weighting verified certs and documentation — and it stores each card’s cert and details so the record builds itself as you add slabs.
