What Is the MeiGray Group?

The MeiGray Groupis a game-worn and game-used memorabilia authentication company. It researches, photo-matches, and issues holograms and letters of authenticity for jerseys and equipment, and it's the authenticator behind a number of official league and team game-worn programs — work it's built its name on primarily in hockey, alongside baseball and basketball programs. That combination of hands-on team access and photo-matching research is what distinguishes it from a general third-party authenticator working only from photos submitted after the fact.

• Licensed game-worn programs— MeiGray has partnered directly with leagues and teams to document and authenticate jerseys and equipment as they come off the ice or field, pairing physical inventory with contemporaneous records rather than reconstructing use after the fact.
• Photo and video matching— researchers compare an item's unique wear marks, tagging, and repairs against broadcast footage and game photography to confirm it was worn or used in a specific game, the same core technique covered in what photo-matching is.
• Hologram and certificate program— authenticated items ship with a numbered MeiGray hologram and a corresponding letter of authenticity, which can be looked up against MeiGray's records the same way a JSA autograph certificate can be verified.
• Auctions of house-authenticated inventory— MeiGray also runs its own periodic auctions of game-worn material it has authenticated, in addition to authenticating items consigned through other auction houses.

• vs. MEARS — MEARS grades game-used bats and equipment on its own A1–A10 scale and is best known for baseball. MeiGray's strongest track record is hockey and licensed team-level programs, though both rely on photo-matching as core evidence.
• vs. JSA — JSA authenticates signatures on autographed items. MeiGray focuses on game-worn and game-used equipment itself rather than on-item signatures, though the two have collaborated on authenticating signed game-worn pieces where both an autograph opinion and a game-worn opinion are needed.

• Verify the hologram number.Cross-check the numbered hologram against MeiGray's own records rather than relying on the seller's description alone.
• Check whether the item is photo-matched or program-sourced.A licensed team program item with documented chain of custody and a photo-matched item are both strong, but for different reasons — read the letter of authenticity to see which applies.
• Confirm the sport and era fit MeiGray's core strength.Its deepest track record is hockey; for other sports, compare its opinion against the item's auction house or other third-party documentation.
