J T Sports is proud to offer PSA Authentication & Grading -- including photo-matching -- for professional model game used bats and game worn gloves. PSA is a division of Collectors Universe, the nation’s leader in third party Authentication & Grading Services for your high value collectibles.

Bats submitted for PSA Authentication and Grading will be evaluated by PSA's 25 step procedure to determine the authenticity of the bat and it’s extent of game use by the player. Resources at hand include a substantial library of player images from 1900 to the present, an extensive database of professional model game used bats and access to detailed player ordering records allowing us to determine specific information regarding bats ordered by the players.

Professional model gloves are measured against criteria developed by the foremost authority on game used gloves in the country, Dennis Esken. As with game used bats, our glove resources include a sizable image database, complemented by our database of PSA authenticated professional player gloves and access to manufacturers information, highlighted by player requests customizing the glove to their specifications.

Our team at Sports Investors Authentication exists to provide the highest overall quality sports memorabilia authentication services. We are setting the standard with our collective expertise, genuine care for our clients and partners, and bringing integrity to the industry.

For photo matching, SPI will provide an extensive letter detailing a full submission evaluation. Delineates item specifications, portrays general item photos, designation of game use (if applicable), identification of performance and milestones (if any), brief explanation of provenance (case by case variation), and contains a final opinion with Managing Member and Lead Authenticator signatures.

Proving a piece of sports memorabilia was used in-game can increase its value tremendously. It takes time and patience to uncover these matches, and for most collectors, this time is simply not available.
