JSA and MeiGray Collaborate to Provide a Seamless Submission Experience for Signed Game-worn Memorabilia

JSA, the world leader in autograph authentication, and MeiGray, the most trusted name in photo-matching and authenticating game-worn memorabilia, today announced a collaboration that will streamline authentication for one of the hobby’s most valuable asset classes: signed game-worn memorabilia.

Beginning April 16, 2026, customers submitting through MeiGray’s online submission form can request both MeiGray photo-matching and JSA autograph authentication as part of the same submission.

A More Efficient Path for Collectors

Historically, collectors seeking both autograph authentication and photo-matching have needed to navigate two separate submission paths. That meant completing multiple submissions for the same item and coordinating across different service providers.

Through this collaboration, collectors and dealers can access both services from the industry’s leading experts through a single, streamlined submission process. To request dual authentication, users simply visit MeiGray’s website, select the Dual Authentication tier, enter their item details, complete a single payment, and ship the item to MeiGray. From there, MeiGray and JSA independently perform their authentication services, with items returned to the collector within approximately eight weeks. As an added benefit, collectors who submit through this collaboration receive a 10% discount on JSA services.

“Collectors who own signed, game-worn memorabilia have traditionally needed to work with separate companies for photo-matching and autograph authentication,” said Barry Meisel, President and CEO of MeiGray. “This collaboration with JSA brings two trusted services together in a way that makes the process simpler and more efficient for collectors and dealers. We’ve long respected JSA’s expertise in autograph authentication, and we’re pleased to offer their services directly through our submission process.”

“Signed game-worn memorabilia represents some of the most desirable material in the hobby, and collectors want confidence in both the autograph and the game use,” said James Spence III, Senior Vice President of JSA. “MeiGray has built an exceptional reputation for photo-matching, and we’re excited to make it easier for collectors to access JSA authentication alongside their services. This collaboration brings together two leaders in the field and provides collectors with a clear and efficient path to authenticating these items.”

Submitting for JSA Autograph Authentication through MeiGray

To submit signed game-worn, game-used or game-issued memorabilia, simply complete the online submission form on MeiGray’s website and select the "Dual Authentication" tier via Authentication. All JSA submissions will receive a JSA letter of authenticity (LOA).

MeiGray and JSA services are available for both mail-in submissions and drop-off at MeiGray’s New Jersey headquarters:

MeiGray Group, LLC
185 Industrial Pkwy
Branchburg, New Jersey 08876

Once services are completed, submitted items and both MeiGray and JSA Letters of Authenticity will be returned to the address provided on the submission form.

Pricing for JSA Autograph Authentication

JSA autograph authentication is available for any signed item submitted for MeiGray photo-matching.

JSA’s authentication fees are based on the signer’s name and are in addition to MeiGray’s photo-matching fees. As part of this collaboration, customers submitting through MeiGray will receive introductory pricing of 10% off JSA’s standard LOA retail rates.

Autograph grading is also available for an additional fee, with pricing determined by signer name. Please note that only memorabilia with two or fewer autographs are eligible for autograph grading.
