7 Red Flags That Autographed Memorabilia Is Fake

THE SCALE OF THE PROBLEM

According to the FBI's Operation Bullpen investigation, industry experts estimate that between 70 and 90 percent of all autographed sports memorabilia sold online today is forged or misrepresented. The FBI specifically put the figure at 75 to 80 percent for items sold through online channels.

That means the majority of signed items you see listed online are likely not what they claim to be.

⚠  Red Flag #1: No Verifiable COA Issuer

A Certificate of Authenticity is only as credible as the company behind it. If the COA has no business name, no physical address, no phone number, and no website — it is a worthless piece of paper. Any printer can produce a professional-looking certificate. What cannot be faked is a verifiable business with a real address and a trackable history.

The test is simple: take the issuer's name and search for them online. Can you find their website? Their address? Customer reviews? Do they have a serial number verification portal? If any of these are missing, the COA should be treated as suspect regardless of how official it looks on the page.

What to do: Look up the issuer independently before purchasing. If they have no verifiable online presence, contact information, or serial number database, walk away.

⚠  Red Flag #2: The Signature Looks Too Perfect

Genuine autographs are signed quickly, often under imperfect conditions   at events, through crowds, in backstage settings. Real signatures show natural variation in pressure, speed, stroke angle, and ink flow. No two genuine autographs from the same player are ever exactly identical.

Counterfeit autographs whether produced by autopen machines, rubber stamps, or skilled forgers working from photo references tend to look too clean. Autopens produce mechanically precise lines with consistent pressure throughout. Stamped or printed signatures show no ink variation at all. If a signature looks like it was drawn slowly and carefully, or if multiple items from the same seller show autographs that look pixel-for-pixel identical, it is almost certainly not genuine.

What to do: Compare the signature against known authentic examples available through PSA's SMR Price Guide or Heritage Auctions' sold lots database. Natural variation and slight imperfection are signs of authenticity not flaws.

⚠  Red Flag #3: The Price Is Suspiciously Low

This is the most common lure in memorabilia fraud and the one most buyers fall for. A Tom Brady signed jersey for $95. A Kobe Bryant signed photo for $49. A Ted Williams autographed bat for $150. These prices feel like incredible luck and they should, because they are not real.

Authenticated Hall of Famer signatures command premium prices because the authentication process has real costs, the signings have real logistics, and demand genuinely outstrips supply for the most desirable athletes. A genuine Brady signed jersey with a witnessed COA costs $3,500 to $6,000. If someone is selling it for $200, they are not giving you a bargain they are selling you a fake.

What to do: Research the realistic market price for any item before purchasing. Use Heritage Auctions, eBay sold listings filtered to completed sales, and PSA's price guide as reference points. If a price is dramatically below market, assume there is a reason.

⚠  Red Flag #4: No Information on When or Where the Item Was Signed

Every legitimate dealer of autographed memorabilia knows exactly when and where each item in their catalog was signed. This is not optional information  it is foundational to provenance. A genuine piece has a specific signing event attached to it: a date, a location, a witness.

When sellers respond to this question with vague answers 'at a signing event,' 'through our authenticator,' 'at a trade show sometime last year'  it is a red flag. Reputable dealers provide specific answers: the name of the event, the date, who was present. Gallery at 759 Main, for example, can document every signing in its catalog because Gallery staff were physically present at each one.

What to do: Before buying, ask directly: when was this item signed, where, and who was present? A legitimate seller will answer immediately and specifically. Vague or evasive answers are a clear warning sign.

⚠  Red Flag #5: The Ink Looks Uniform No Pressure Variation

When a person signs their name, natural variations in hand movement cause the ink to appear slightly thicker in some places and thinner in others. At the start of a stroke the pen deposits more ink; at the end, less. Curved portions of letters show different pressure than straight ones. This variation is a physical signature of genuine hand-signing.

Printed, stamped, and digitally reproduced signatures show none of this variation. The ink line is consistent throughout the same width, the same density, from start to finish. If you examine a signature under magnification and the ink line looks mechanical   perfectly uniform with no variation   it was almost certainly not signed by hand.

What to do: Examine the signature closely, ideally under magnification if available. Look for natural ink variation and slight imperfections in stroke width. Perfectly uniform ink is a strong indicator of a printed or stamped signature.

⚠  Red Flag #6: The Seller Claims to Have Every Famous Athlete

No legitimate memorabilia gallery has unlimited access to every major athlete in every sport. Genuine relationships with athletes for signing purposes are rare, specific, and hard-won. A gallery that stocks authenticated items from Tom Brady, LeBron James, Lionel Messi, Tiger Woods, Taylor Swift, and 400 other superstars simultaneously   with no apparent selectivity should raise immediate suspicion.

Real dealers are selective because real authentication is selective. Gallery at 759 Main's catalog of 771+ items represents years of building specific relationships and attending specific signing events. Sellers who appear to have everything have usually authenticated nothing   they are sourcing unverified items from bulk suppliers and attaching their own COA documents.

What to do: Treat breadth without specialisation as a warning sign. A seller with 5,000 autographed items from every imaginable athlete is far less trustworthy than a focused dealer with 100 items they can specifically account for.

⚠  Red Flag #7: No Return Policy or Authenticity Guarantee

Every reputable memorabilia dealer stands behind their items with a clear, written return policy that explicitly covers authenticity disputes. This is non-negotiable. If a piece turns out to be a forgery, a legitimate dealer will make it right  full stop.

Sellers who offer no returns, who limit returns to 'item not as described' rather than authenticity, or who include language that makes authenticity disputes difficult to pursue are signalling that they are not confident in what they are selling. The absence of an authenticity guarantee is itself evidence that the seller knows the item may not be genuine.

What to do: Read the full return and authenticity policy before purchasing anything. The policy should explicitly state that items are guaranteed authentic and that authenticity disputes are covered. If it does not, find a seller whose policy does.

The Bottom Line

If you are buying autographed memorabilia online, run through all seven red flags before committing. If any one of them is present, walk away. The safest purchase you can make is from a dealer who witnesses every signing in person   because that eliminates the need to authenticate after the fact.
