Introduction
The Major League Baseball Authentication Program has set the standard for sports memorabilia authentication. Major League Baseball is the first and only professional sports league to implement a program that easily distinguishes authenticated autographs and game-used memorabilia from other items on the market.

This program - which combines the services of a third-party authenticator with a state-of-the-art hologram, a serial numbering system and an online verification process - guarantees the authenticity of its autographed and game-used items.

Authentication
Autographed and game-used items in the MLB Authentication Program are currently authenticated by individuals specifically trained to authenticate autograph signings and the removal of items that they personally witness as used in game.

Posting on MLB.com
Items and their unique identification numbers are processed and posted on MLB.com, the program's official site, for easy reference by consumers.

Assignment of a Unique ID Number
Once witnessed, every authenticated item is affixed with a tamper-proof hologram created by OpSec, U.S. to identify its authenticity.
