Off-duty law enforcement officers working as independent contractors are assigned by Authenticators, Inc. to authenticate autographs and game-used memorabilia at every Major League Baseball game. Only those items that an authenticator actually witnesses being signed and/or used in a game may be eligible for authentication under the MLB Authentication Program. Once witnessed, authenticated items receive a tamper-proof hologram created by OpSec, U.S. with a unique alphanumeric combination to easily identify their authenticity.
Examples of the tamper-proof holograms unique to the MLB Authentication Program can be found below:

In addition to the holograms featured on authenticated memorabilia, different holograms are produced by OpSec, U.S. for use on Major League Baseball Properties licensed products. These holograms, also with unique alphanumeric combinations, allow fans to easily identify merchandise as officially licensed by MLBP. These holograms are NOT used for the authentication of game-used or autographed products and, therefore, will not show up on the verification system located on MLB.com/authentication.
Images of some of the holograms used to identify licensed merchandise are featured below:
