Why collectibles need this
Authentication and Provenance Are Everything in the Collectibles Market.
The collectibles market — trading cards, coins, stamps, memorabilia, vintage toys, sports cards — is driven by authenticity and provenance. Counterfeits are widespread. Grading certificates can be separated from the item. Ownership history is often undocumented. An Ownich Digital Ownership Certificate creates a permanent, tamper-evident record that links authentication, grading, and ownership history to the specific item.

VerifiedWhat it covers
What a Collectibles Certificate Records
Grading certificates
PSA, BGS, CGC, and other grading certificates are uploaded and permanently linked to the item. They cannot be separated, substituted, or applied to a different item.
Authentication records
Authentication reports from recognised authorities are recorded and cryptographically linked. The authentication history is transparent and tamper-evident.
Population and rarity data
Population report data — how many examples exist at a given grade — is recorded at the time of certification and linked to the certificate.
Ownership chain
Every ownership transfer is recorded atomically. The complete ownership history — who owned the item, from when, to when — is permanently attached to the record.
Resale verification
Buyers can verify the item's authentication, grading, and ownership history before completing a purchase. No account needed. No fee.
Insurance and storage
Insurers and storage facilities can verify item identity and value independently — without relying on paper documents that may be lost or disputed.
