Who we are
Founded by Collectors, for Collectors
Icon Sport Investments was founded in 2016 by a team of lifelong sports collectors who were frustrated by inconsistent authentication standards in the industry. We believed collectors deserved better — a service that combined rigorous forensic methodology with genuine passion for the hobby.
What began as a boutique authentication service for high-value jerseys has grown into a comprehensive platform covering autographs, trading cards, and rare memorabilia across every major sport. Today, our certificates are recognized and trusted by collectors, dealers, and auction houses nationwide.
Every item we authenticate receives the same meticulous attention — whether it's a rookie card or a championship-era game-worn jersey. Our reputation is built one certificate at a time.
Our process
How We Authenticate
Every item undergoes a multi-stage review before a certificate is issued. No shortcuts. No exceptions.
Initial Submission Review
We review your submission details, photos, and provenance documentation to determine if the item qualifies for full authentication.
Physical Examination
Our experts conduct a hands-on inspection examining materials, construction, aging patterns, and physical characteristics consistent with the claimed era and origin.
Signature & Provenance Analysis
For autographed items, signatures are compared against a database of verified exemplars. Provenance documentation is cross-referenced with known records.
Photo Matching
Where possible, game-worn items are photo-matched to archival footage and photography to confirm on-field use.
Certificate Issuance
Authenticated items receive a unique certificate number embedded in the item. The record is permanently stored in our verification database.
