The rich patina of the game can be found in the seams of game used balls, which are hologrammed and recorded at each MLB game by official MLB Authenticators.
Each MLB artifact is authenticated under the auspices of the MLB Authentication Program and carries a uniquely numbered hologram that allows fans to verify their item at MLB.com/authentication. MLB Authenticators witness, log, and adhere holograms to each baseball that comes out of play. Thus the details of each baseball are linked to a unique hologram number in this online database.Balls acquired by Tokens & Icons are hand-cut and assembled. An MLB Authenticator affixes a secure hologram to every bottle opener (just as he does for the cuff links shown right) and logs the information. When fans enter the bottle opener's hologram into MLB's site, it reveals the date and rival team of the game in which the baseball was removed from play.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 game used sports authentication. MLB stations an authenticator at every game played throughout the season. This demonstrates a commitment to ensuring all game used artifacts are genuine. For more information, please visit Authentication.
