Setting the Standard

The Major League Baseball Authentication Program is the most comprehensive league-wide memorabilia authentication initiative in professional sports. Since its launch in 2001, it 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.
