There is always a person at major league baseball games who authenticates certain items. A player's 1st hit or home run ball, a home run caught by a fan, a pitcher's 2,000th strike out, things like that.

Who determines which items are authenticated, and is that person hired by MLB, the ballpark, or whom?


Off-duty law enforcement officers working as independent contractors are assigned by Authenticators, Inc. for Major League Baseball Properties to authenticate autographs and game-used memorabilia at every Major League Baseball game. Only those items that an authenticator actually witnesses being signed or used in a game may be eligible for authentication under the MLB Authentication Program.
