$250,000 Autograph Scam Exposes Major Flaws in the Memorabilia Market

For nearly a decade, Anthony J. Tremayne operated in the shadows of the sports memorabilia industry, selling forged autographs to unsuspecting collectors while hiding behind polished websites and fake certificates. His operation, which stretched from 2010 to 2019, may have fooled hundreds—and netted over $250,000 in fraudulent sales before it was brought to a halt by federal investigators.

Tremayne, once based in California, built a business on deception. He didn’t just forge autographs—he created an entire ecosystem to support the illusion. Replica trophies, fake game-used gear, and forged signatures from athletes and celebrities were paired with convincing Certificates of Authenticity that mimicked those issued by trusted authentication services. His online presence added another layer of credibility, helping him blend in among legitimate dealers and auctioneers.
What made his scam so effective was its presentation. Tremayne’s listings felt professional. His certificates looked official. And the items? They were the kind of memorabilia any collector might proudly display—signed boxing gloves, autographed jerseys, even Pro Football Hall of Fame jackets.

Authorities estimate the total amount lost in the scam to be about $250,000, but internal records suggest his attempted fraud may have reached closer to $550,000.

The scheme began to unravel in 2019 when an undercover FBI agent purchased what Tremayne claimed was a signed photo from members of the reality show Keeping Up with the Kardashians for $200. That purchase helped build a larger case against him, ultimately leading to his guilty plea. While charged with over a dozen counts, Tremayne settled on a single count of mail fraud. He now faces up to 20 years in prison, with sentencing set for August 2025.

This case cuts deep within the collecting community. It serves as a reminder of how vulnerable collectors can be—even those who believe they know what to look for. Forgers today operate with sophistication. They understand the psychology of buyers, the aesthetics of authenticity, and the blind spots within the hobby.

For longtime collectors, the fallout stings. The damage isn’t just financial—it erodes the trust that the market depends on. When certificates can be faked and listings look legitimate, even experienced buyers can be left second-guessing their purchases.

In the wake of this scandal, collectors are advised to be cautious. Stick to well-established sellers, and when buying from private individuals, demand third-party verification. Use authentication services with a solid track record and be skeptical of deals that seem too good to be true.

Tremayne’s case isn’t just about one person’s wrongdoing—it highlights a growing challenge in an industry built on passion and belief. The hobby will continue, but collectors may think twice before clicking “buy” without a deeper look behind the signature.
