For collectors of sports memorabilia, the paramount question is always: Is it genuine? Noah Garden, chief deputy officer for Major League Baseball, recalled growing up doubting the authenticity of every autograph he obtained. That pervasive uncertainty drove the creation of the MLB Authentication Program a quarter-century ago, a league-wide initiative that would transform the sports memorabilia landscape.
No other professional sports league operates an authentication program as thorough as Major League Baseball's. Before the program existed, the memorabilia market was reeling from Operation Bullpen, an FBI and IRS investigation that began in the 1990s and estimated that as much as 90 percent of all sports memorabilia at the time was counterfeit. The probe led to 63 charges and convictions, the dismantling of 18 forgery rings, and the seizure of over $4.9 million, according to the FBI.
With fan confidence shattered, MLB and other organizations sought to overhaul their authentication methods, moving beyond the traditional certificates of authenticity—paper documents that had suddenly lost all credibility. For Michael Posner, director of the MLB Authentication Program, its founding marked the moment the league took a definitive stand to protect baseball's history.
The program's core mission is to safeguard all teams, players, and fans by eliminating the ambiguity that breeds distrust. And with the 2026 World Series being contested by two teams that have never won a title—the first such matchup since 1980—the MLB Authentication Program is especially relevant. Regardless of which club emerges victorious, a multitude of historic artifacts will need to be cataloged and preserved, and even more fakes will need to be distinguished from the real thing. That's where the program comes in.
A Collector's Nightmare
In the 1990s, interest in sports memorabilia was skyrocketing. Items were sold on home shopping channels, in malls, and through mail-order catalogs. That heightened demand led to the market being flooded with bad actors peddling fakes. San Diego Padres icon Tony Gwynn, a man who treated his craft with surgical precision, noticed something unsettling close to home. While inspecting merchandise for sale near the Padres stadium, Gwynn realized that the signatures supposedly his were not. This sparked an investigation that uncovered a staggering truth: a massive portion of athlete autographs on the market were fraudulent.
This collapse of market trust signaled the end of opinion-based authentication. MLB realized that to preserve the game's soul, it had to protect history with its own investigative rigor. The league would need to devise a system in which truth was witnessed and documented, not guessed.
Eyes on the Game
MLB now utilizes a comprehensive authentication program to verify the legitimacy of game-used equipment and autographed memorabilia. Established in 2001, the initiative employs retired and off-duty law enforcement officers who personally witness items being used or signed to obtain official certification. Validated pieces receive a tamper-proof holographic sticker with a unique serial number, allowing fans to research specific details through an online database.
MLB currently employs its third-generation hologram technology, developed by OpSec/Crane Authentication. Originally produced in Lancaster, Pa., these holograms are a critical security measure. The shims used to manufacture the holograms never leave the secure factory room, and the central office maintains the technical ability to void any hologram sequences that are lost or misplaced before they can be entered into the system.
The program's security is built on a philosophy of constant evolution. One of Posner's favorite sayings is, "When you build a better mousetrap, they build a better mouse." This necessitates a multilayered defense against increasingly sophisticated counterfeiting efforts. The holographic stickers feature a unique serial number, a three-letter validation code, a QR code for quick reference, the MLB logo, and a tamper-proof design. They are engineered so that any attempt to remove them leaves permanent marks behind and the sticker comes apart, making it impossible to transfer a legitimate seal to a forged item.
The eyes on the game serve as authenticators that follow these steps: First, witness the moment; second, secure the item in custody for the unique hologram to be applied; and third, enter the item into the official authentication database. Authenticators arrive at the venue 90 minutes before first pitch. Their initial task is to formulate an authentication plan, which involves meeting with both clubs to identify specific needs, such as tracking game-worn equipment or collecting field dirt, and reviewing a centralized list of impending achievements (e.g., a player approaching 3,000 hits or 500 home runs).
To maintain the highest integrity, a minimum of two authenticators is required per game and up to 12 for premier events like the All-Star Game. The 2026 World Series has six authenticators at each game. During play, they utilize a tablet-based system to record every pitch in real time. This system captures a granular data set for every authenticated ball: pitcher and batter, inning and pitch count within the ball's usage, pitch velocity, launch angle, and exit velocity. All of this information is then stored in a publicly accessible database. It includes the game date, the teams, the players involved, and the specific moment for each item, plus pitch type and velocity for game-used balls. This turns a cool piece of memorabilia into a time capsule.
In 2025, MLB staff divided and conquered, spending a week at every stadium to train authenticators on the fourth-generation interface. "(The new system) greatly improved the information coming in," Posner said. It also streamlined the audit process, allowing for faster verification for the end consumer. The process concludes in the clubhouse, where authenticators witness the signing and tagging of jerseys, cleats, and equipment. This clubhouse access is what allows the program to function at a level unparalleled by any other professional sports league.
Because the program adheres to a strict direct witnessing standard, items that leave an authenticator's sight, such as home run balls hit into the stands, are generally not authenticated. Posner believes this rigor is essential. "We have to have a standard that becomes the tentpole that supports the 11 (million) to 12 million items that we have authenticated," he said. This rigorous system protects the sport's historical integrity while supporting a high-value secondary market for collectors and partners like Topps. Beyond commercial sales, the program also helps preserve and document iconic artifacts for the National Baseball Hall of Fame and Museum.
Who Owns History?
While USA hockey hero Jack Hughes argued with the Hockey Hall of Fame over possession of his Olympic golden-goal puck, MLB handles memorabilia ownership differently. Teams, the league, and the Baseball Hall of Fame always ask players involved for permission before using or keeping anything from a milestone. Traditionally, uniforms (jerseys, hats, socks) are purchased by the individual clubs. Bats, gloves, and cleats are often the players' equipment provided by the manufacturers they endorse. Baseballs are different, though. Any ball that ends up in the stands becomes the property of whoever finds it, and balls that remain within the field of play are either retained by the home team or claimed as souvenirs by players.
More than just game-used balls and bats that have been authenticated—bases, player-worn jerseys, locker nameplates, bottles of field dirt, and even dugout-used espresso machines from the World Baseball Classic have all been authenticated by the program. "If it's come through a ballpark and is part of the history of the sport, we've authenticated it," Posner said. That includes the Debut Patches that are worn on players' jerseys during their first MLB appearance and then put into one-of-a-kind baseball cards by Topps, a practice that began in 2023. "You know, there's always the debate of the real, true rookie card between Bowman and Topps," Garden said, "but now this is it, the real card that everyone chases that was worn and authenticated; it's the Willy Wonka golden ticket."
The Latest Iteration of Authentication
After 25 years, the program is evolving to meet the challenges of the pitch clock era. The 2025 system upgrades focus on consistent data entry, ensuring a base retrieved in the Bronx is described with the same forensic detail as one in Seattle. The reduced time between pitches means authenticators must work with the focus of a cockpit crew. As Posner describes the 2025 digital upgrades: "The pilot isn't taking his eyes off the sky." The authenticator stays locked on the field, while the technology handles the logging.
Garden and Posner echoed the impact that technology has as a mechanism in their authentication program. "Every year, with new advancements, we can do things that we couldn't do a few years ago," Posner said. "If I see something that's even remotely applicable to what we're doing, we're going to dive into it and see where it goes. And I think that's where we're continuing to do the work, even as we speak. On programs that will expand our reach and create a better experience for customers."
