Sports Autograph’s – How Much is Fake?

Sports Autographs: How Much Is Fake?

It’s hard to imagine paying $500, $2,000 or more for a Michael Jordan autographed item only to discover it’s fake. And even when an item comes with an “authentication” label, buyers can still end up with counterfeit memorabilia, so no matter the athlete, the financial risk is real.

Michael Jordan is only an example. The same issue can affect many high-value autographed sports (and non-sports) items.

In 2000, during Operation Bullpen, U.S. investigators reported that the forged-celebrity-and-sports-memorabilia problem was widespread, estimating that anywhere from 50% to 90% of high-profile items in the market could be counterfeit (U.S. Department of Justice [DOJ], 2000). The FBI later explained that it was “impossible to definitively estimate” the percentage of forged memorabilia but also noted that most industry experts “concede” over half of the most sought-after athletes’ and celebrities’ autographed memorabilia is forged (Federal Bureau of Investigation [FBI], 2005). That’s the uncomfortable truth: fakes aren’t rare, and the real question becomes how you reduce your odds.

“Authenticated” isn’t the same thing as certainty

We see our fair share of submissions at Shuler Authentication Services (SAS) that turn out to be phony, and we assume other authentication services face the same challenge. At trade shows, we’re asked constantly: “How much of this stuff is fake?” The short answer is “a lot.”

So, what’s the gap between the word “authenticated” and what buyers often assume?

In practice, a certificate reflects an expert’s opinion based on an examination and the evidence available at the time of review. It’s not a magic guarantee that removes all uncertainty in every possible scenario. When you commission a third-party authentication company, such as SAS—you’re paying for a professional opinion grounded in specialized knowledge and the evidence we can assess. In most cases, this includes reviewing provenance and handwriting/signature characteristics, not firsthand verification of the moment of signing. After examining the item, SAS issues a certificate reflecting our expert opinion that the autograph is authentic.

How fakes are made (and why evidence quality matters)

Counterfeit autographs rarely depend on a single “perfect trick.” They tend to follow patterns: copied signature design, repeated simulations that look convincing at a glance, and frequently documentation or a story meant to make an item feel legitimate.

That means the evidence you provide (and the evidence you have as a buyer) matters as much as the signature itself. Strong, relevant evidence supports stronger conclusions. Limited or unclear evidence—such as vague provenance, low-quality photos, or insufficient reference information—can restrict what can be concluded, even by highly trained examiners.

What forensic document examination adds

SAS is a forensic document and questioned document examination company. Our work is built around disciplined examination principles used in forensic settings: we examine writing and signature features as part of a broader evidentiary picture, consider the quality and relevance of the materials provided, and document the basis for our conclusions. That process matters because signatures aren’t just visual patterns, they reflect an individual’s habits, skill level, and writing dynamics. Those patterns must be assessed in context.

A quick risk-reduction checklist before you buy

If you’re considering making a purchase, especially at higher prices, use these questions as a quick filter:

• What was actually examined? Look for specifics about what evidence supported the opinion, not just the term authenticated.
• How strong is the provenance? Documentation and chain-of-custody reduce uncertainty more than stories do.
• What limitations apply? Certificates should reflect the basis for the opinion and what conclusions can (and can’t) be supported.
• Does the evidence match the claim? Missing documentation, unclear photos, or inconsistencies are Red Flags, especially for expensive items.

No checklist eliminates risk entirely. But these questions help you avoid paying top dollar based on marketing language instead of examination evidence.

What to do next if you’re unsure

If you’re uncertain about an autograph you’re considering buying (or one you already own), SAS can help you understand what the evidence supports. Contact SAS for a consultation to review item details and photos and discuss what we can conclude (and what limitations may apply) based on the evidence provided. We’ll use our methodologies to give you the best opinion possible.
