Sports memorabilia is only as valuable as its authenticity. That’s why MLB’s authentication program—established in the late ‘90s—has become the gold standard. Designed to combat counterfeits after Tony Gwynn discovered his forged signature in the market, it now ensures fans and collectors get the real deal.
MLB authenticators, all trained law enforcement officers, track every game-used item in real time. When a ball, jersey, bat, or even dirt leaves the field, it’s immediately tagged with a tamper-proof holographic sticker, logged into MLB’s database, and made available for bidding on MLB Auction Marketplace. Over 6 million items have been authenticated since 2001, reinforcing trust in the memorabilia industry.
This process is far from casual. MLB authenticators sit in dugouts, closely watching plays, tracking who handles key items, and ensuring nothing slips through the cracks. A ball that lands in the stands, for example, can’t be authenticated unless retrieved by staff. Some of the most valuable collectibles have come through this system, including Aaron Judge’s 62nd home run ball, which sold for $1.5 million.
This rigorous system ensures that every collectible tells an accurate story. Whether it’s a historic home run ball or a jersey worn in a milestone game, fans can confidently bid on items knowing they’ve been properly authenticated.
With MLB’s authentication program and MLB Auction Marketplace, fans can own a true piece of the game—with confidence.
