There's a common misconception in the collectibles market: if a slab has a real cert number, it's safe to buy. This misunderstands what grading companies actually do — and more importantly, what they don't do.
What Grading Companies Actually Do
PSA, BGS, CGC, and their competitors provide a specific, valuable service: they evaluate a card's condition at a specific point in time, assign a grade, and seal it in a protective case with a unique identifier. That's authentication at inception. It answers one question: was this card genuine and in this condition when it was graded?
That question is valuable. It's also incomplete.
What Grading Companies Don't Do
The moment a graded slab leaves a grading company's facility, the trail goes cold. Grading companies do not track:
- —Who has owned the card since grading
- —Whether the slab has been cracked open and resealed
- —Whether the same cert number appears on multiple slabs simultaneously
- —Whether the card inside still matches the card that was graded
- —Whether the slab has been reported stolen
- —Whether the slab has been flagged by the collector community
“Authentication at inception is not the same as trust across a lifetime of transactions.”
Why This Isn't a Failure — It's a Design Gap
It's important to be clear: this is not a criticism of grading companies. Authentication and provenance tracking are fundamentally different problems requiring different infrastructure. Grading companies were designed to solve authentication. The market has matured to the point where it also needs provenance.
Compare to analogous markets. A car manufacturer certifies a vehicle at production. CARFAX tracks what happens afterward. Both are necessary. Neither replaces the other. The collectibles market has had the equivalent of car manufacturers for decades. It's been missing the equivalent of CARFAX.
The Provenance Layer
SlabProof operates in the space grading companies were never designed to cover. We don't grade cards. We track them. The Cerfinity™ Digital Provenance infrastructure creates an immutable chain of custody that follows a slab through every transaction, across every marketplace, for the life of the collectible.
This is complementary to grading, not competitive. Every card that PSA grades is a potential SlabProof registration. We take the authentication record that grading companies create and extend it forward through time.
