Memorabilia Authentication

MLB Authentication Program

Major League Alumni Marketing works through the Major League Baseball Authentication Program for the most comprehensive league-wide memorabilia authentication initiative in professional sports. Since its launch in 2001, the Major League Baseball Authentication Program has become the industry standard for autographed and game-used sports memorabilia authentication. Designed to distinguish officially authenticated MLB memorabilia from other items on the market, the program offers an objective third-party authentication system that guarantees genuine memorabilia for all MLB fans.

All MLAM Exclusive Athlete items are MLB Authenticated.

MLB Holograms are applied and updated at the discretion of the MLB Authentication Program and its employees and are not guaranteed by Major League Alumni Marketing.

Other Authentication

Throughout the year, MLAM collects and sells autographed memorabilia from both active and alumni Major League Baseball players. All items shipped from Major League Alumni Marketing are obtained directly from the athlete or a reputable source of sports memorabilia, including but not limited to TriStar Productions, Fanatics Authentics, GT Sports Marketing, MAB Celebrity Services, and more.

In addition to the Major League Baseball Authentication Program, MLAM also uses authentication companies PSA/DNA, JSA and Beckett.
