The Major League Baseball Authentication Program has set the standard for sports memorabilia authentication. Major League Baseball has teamed with the personal services firm Deloitte and Touche and is the first and only professional sports league to implement a progam that easily distinguishes authenticated autographs and game-used memorabilia from other items on the market.

This program - which combines the services of an independent third-party authenticator with a state-of-the-art hologram, a serial numbering system and an online verification process - guarantees Major League Baseball fans that the items they acquire are 100% authentic.

Every autographed and game-used item in the MLB Authentication Program is authenticated by a Major Leaue Baseball representative. An independent third party authenticator from Deloitte and Touche as a representative of Major League Baseball will attend all approved autograph signings and will witness the removal of all game-used items to be offered by Major League Baseball® as part of the program.

Posting on
Each item and its unique indentification number is processed and posted on the official program Web site - - for easy reference by consumers. Soon collectors will be able to register their authenticated items online for proof of possession.

Assignment of unique id number
Once witnessed, every item will be affixed with one of two tamper-proof holograms (shown left) created by OpSec, U.S. to identify its Major League Baseball authenticity. A round hologram will be applied to baseballs, and a larger tunnel-shaped hologram will be applied to all other items.
