Tell this to the fan who just caught a home run, and there might be a sagging of shoulders — that ball, which required acrobatics to catch and hand-to-hand combat with other fans to retain, doesn't actually have any historical significance in the eyes of Major League Baseball.
Without the telltale MLB authentication hologram sticker and accompanying six-number, two-letter code, that ball is just a ball. No different from one you purchase at the souvenir shop, which is precisely the problem.
Home run balls can't usually be authenticated, as an official authenticator — sitting in an on-field camera well near the home-team dugout — can't physically eyewitness the catch and the struggle to retain the ball that often follows.
The league's authentication program started in 2001 after a late 1990s FBI investigation discovered 75 percent of all autographs in the market were fake. And since three-quarters of the sports memorabilia business was baseball, MLB decided it needed to lead the push to eliminate phony merchandise.
The program now has about four authenticators for all 30 teams in the league, making for about 150 in total around the U.S., Puerto Rico and the Dominican Republic. At least one is present at all 2,430 regular-season games as well as postseason, spring training, All-Star week, the World Baseball Classic and other team- or league-sponsored events.
There are home run balls that are authenticated, like the fan who caught former Twins slugger Jim Thome's 600th home run in 2011 at Detroit's Comerica Park. When special milestones are on the horizon, authenticators specially mark every ball used leading up to the hit, so when the fan catches it, security can descend upon him and begin the process of placing the hologram and haggling with the fan about a trade so the ball can reside in an appropriate place instead of a fan's living room.
Authenticated items that mark milestones are often returned to players, given the team for its archives or even forwarded to baseball's Hall of Fame. Many of the items are sold to fans — the Twins have a kiosk where fans can by game-used items from the actual game they are attending. Some items are used for promotions for season-ticket holders or fundraisers.
MLB is the only major sports league with such a vast and comprehensive authentication program. It has collected about 4.8 million individual unique items, averaging about 500,000 new authentications each season. Michael Posner has been at the helm of the program since 2003 and said its only limitation is human reality.
