For collectors, few things are more exciting than owning an autograph from a sports goat. A baseball signed by Babe Ruth. A photo bearing Mickey Mantle’s signature. A piece of memorabilia connected to Michael Jordan, Roberto Clemente, or another icon.
But during the 1990s, there was a serious problem hiding inside the booming sports memorabilia business: a staggering number of those signatures weren’t real. The problem became so widespread that the FBI launched an undercover investigation that would eventually expose a nationwide network of forgers, authenticators, wholesalers, and dealers.
It was called Operation Bullpen, and it became one of the most important fraud investigations in hobby history.
Hobby Boom Creates Demand
By the 1990s, autographed sports memorabilia had developed into an enormous business. The FBI estimated the U.S. autographed memorabilia market at roughly $1 billion annually, while cooperating witnesses and industry experts estimated that forged material represented more than $100 million of that market each year.
The warning signs initially appeared during an FBI investigation in Chicago known as Operation Foul Ball. What appeared to be a regional scheme involving forged autographs of Chicago athletes, including Michael Jordan, turned out to be much larger. Operation Foul Ball ultimately resulted in 14 convictions across five states and gave investigators evidence that autograph fraud was a nationwide problem.
In 1997, the FBI’s San Diego Division began building a larger undercover investigation with the U.S. Attorney’s Office and IRS.
Their strategy was clever. The FBI created a fictional company called the Nihon Trading Company in Oceanside, California. An undercover agent posed as a distributor purchasing American sports memorabilia for customers in Asia.
The cover story solved an important problem for investigators. Agents could purchase fraudulent memorabilia as evidence without putting the counterfeits back into the American marketplace. More importantly, sellers believed the merchandise was heading overseas.
That made some of them surprisingly comfortable discussing exactly what they were doing.
Rise Of The Forgery Factory
Over the course of the investigation, undercover agents recorded conversations with people involved in producing, authenticating, and distributing fake memorabilia. According to the FBI, Phase I alone generated well over 1,000 consensually recorded audio and video recordings. Some conversations revealed just how brazen the operation had become.
One conspirator joked that Mickey Mantle essentially still had an arm reaching out of the grave to sign memorabilia. Others discussed forged signatures supposedly produced by athletes after those athletes had already died. The operation also demonstrated that autograph fraud wasn’t simply the work of an isolated guy sitting at a desk practicing signatures.
It had become a supply chain.

Operation Bullpen had some unlikely allies: three of baseball’s biggest stars. Tony Gwynn, Mark McGwire, and Sammy Sosa. This trio worked with the FBI to help investigators identify forged signatures.
Gwynn’s involvement reportedly began after he walked into the San Diego Padres’ own team gift shop and noticed that a display of signed baseballs and photographs contained signatures he immediately recognized as forgeries. Gwynn approached the FBI.
Investigators later brought Sosa and McGwire into the effort as well. McGwire and Sosa had similar experiences. Seeing their autographs being passed around on items they knew they had never signed during the heat of their record-smashing 1999 season.
Their involvement underscored just how deeply counterfeit memorabilia had penetrated the hobby: if forged autographs could fool the MLB, everyday collectors faced an even greater challenge.
The Counterfeit Conundrum
Bringing the counterfeit items to the market was a team effort. There were people producing the signatures. Others distributed the merchandise. Some fraudulently authenticated items. Dealers and retailers then moved the material into the marketplace, where ordinary collectors could encounter it alongside legitimate memorabilia.
The names appearing on the merchandise were among the most desirable in collecting. Goats of the past, and top players of the present:
-
- Babe Ruth
- Mickey Mantle
- Roberto Clemente
- Tony Gwynn
- Mark Mcgwire
- Sammy Sosa
The fraud extended well beyond sports, too. Investigators encountered supposed autographs from celebrities and historical figures, including Elvis Presley, Walt Disney, James Dean, George Washington, and even Mother Teresa. You have to be a special kind of lowlife to forge a saint’s autograph, and yet despite making fistfuls of cash, their greed could not be satisfied.
Operation Bullpen: 1999 Takedown
By late 1999, investigators were ready to move. On October 13, 1999, more than 400 FBI and IRS agents participated in a massive series of searches around the country. Authorities executed more than 60 search warrants.
What they recovered illustrated the extraordinary scale of the operation. Investigators seized approximately $10 million worth of forged memorabilia, more than $500,000 in cash, and more than 10,000 forged baseballs.
They also recovered hundreds of so-called “cut” autographs, signatures on pieces of paper that could be incorporated into displays or other collectible items. Supposed signers included historical and entertainment figures who had been dead for decades.
On April 11, 2000, Phase I culminated in charges against 26 people. According to the FBI’s later accounting, all 26 were convicted.
But Operation Bullpen wasn’t finished. Not even close.
The Investigation Grows
Phase II expanded the investigation nationwide and placed greater emphasis on celebrity memorabilia and internet sales. That last part was especially significant. Before you set that next eBay snipe, listen up and pay attention.
Collectors were increasingly buying memorabilia online, and the internet gave dishonest sellers access to customers far beyond their local markets. The same technology that made collecting easier also created new opportunities for counterfeiters. Sound familiar?
The FBI produced another 2,000-plus recordings during Phase II and dismantled additional forgery rings. By the FBI’s final accounting of the operation, the numbers were remarkable:
-
- 63 people charged and convicted.
- 18 forgery rings dismantled.
- 75 search warrants executed.
- More than $4.9 million in assets seized.
- More than $300,000 in restitution paid to over 1,000 victims.
Tens of thousands of pieces of fraudulent memorabilia were removed from circulation. But that’s barely a drop in the bucket. Most (conservative) estimates place that number at about 10% of the total value of forged memorabilia that was sold.

Despite the enormous scale of the raids, most of the damage had already been done. The FBI seized roughly $10 million in forged memorabilia in the 1999 takedown, but the network was linked to the creation and sale of as much as $100 million in fakes. That meant countless counterfeits had already entered private collections, and many may still be circulating today.
Because people realize that you’ve got to be careful when you buy. But my opinion is, there’s still a lot of bad stuff out there because a lot of it was done in the 1990s and a lot of people are still holding that stuff and don’t know it.” – John Ferreira (FBI undercover agent for Operation Bullpen)
A cautionary tale, to say the least, for those still buying memorabilia today without any form of authentication from a reputable company.
Operation Bullpen Changed Authentication
Perhaps Operation Bullpen’s biggest legacy wasn’t the arrests. It was what happened to the hobby afterward. The investigation demonstrated a fundamental weakness in the memorabilia business: a certificate of authenticity was only as trustworthy as the person or company issuing it.
A lie is still a lie no matter how many times it gets told. A fake autograph accompanied by a questionable certificate is still a fake autograph.
Around the conclusion of Phase I, Major League Baseball introduced its own memorabilia authentication program. Rather than attempting to determine whether a signature looked correct sometime later, representatives could witness items being signed and attach uniquely numbered holograms tied to a database.
Other companies developed similar witnessed-signing systems. For collectors, that distinction remains important today. There is a significant difference between opinion-based authentication, where an expert examines an autograph after the fact, and witnessed authentication, where an authorized representative actually observes the item being signed.
Neither Operation Bullpen nor modern authentication eliminated forgery from the hobby. Counterfeiters adapt, technology changes, and online marketplaces make it possible for questionable material to reach enormous audiences.
But Operation Bullpen fundamentally changed the conversation.
An Expensive Lesson For Collectors
More than two decades later, Operation Bullpen remains a cautionary tale for anyone buying autographed memorabilia. A convincing signature isn’t necessarily authentic. A professional-looking certificate isn’t necessarily meaningful.
An online seller having hundreds of supposedly rare autographs isn’t necessarily evidence of incredible connections; it may be a reason to ask more questions. Collectors should research provenance, understand who authenticated an item, examine the reputation of the seller, and remember one of the oldest rules in collecting:
If the deal seems too good to be true, it probably deserves a much closer look before money is exchanged.
Operation Bullpen exposed just how sophisticated autograph fraud could become when the perfect storm of demand, money, and misplaced trust collided. For collectors, its legacy is ultimately about something much more than FBI raids or counterfeit signatures. It’s about the breach of trust between buyer and seller, a trend that still happens far too often today.
