Collecting signed sports memorabilia can be exciting — whether you're a die-hard fan, a serious collector, or just someone who came across a listing that seemed like a great deal. But what if the autograph you just spent good money on… isn’t real?

At Signatrue.ai, we’re seeing this happen way too often. That’s exactly why we built a tool that uses AI and machine learning to verify signatures by analyzing tiny details like pressure, stroke direction, pen lifts, and more. It’s fast, affordable, and brutally honest — and it’s built from real forensic principles used in signature analysis.

Recently, we ran checks on some signed football (soccer) memorabilia sold through one of the biggest online marketplaces — and what we found was pretty concerning.

A Lot of Fake Autographs Are Slipping Through — And People Are Overpaying

One listing stood out: a 2010 Topps Match Attax card featuring what was claimed to be a Pelé autograph.

The card sold for £234.68 (just over $300 USD) to someone who believed they were getting a piece of soccer history. Unfortunately, that trust wasn’t rewarded.

We ran the signature through our system at Signatrue.ai, and it raised some serious red flags.

What Our AI Found

• The stroke direction didn’t match Pelé’s known signature
• The pressure pattern was off
• The curves and flow were inconsistent
• There was no sign of natural hand movement — which you’d expect from a real signature

Bottom line? This card was most likely never signed by Pelé. In fact, we’re confident it never came anywhere near him.

$300 Lost — All for Skipping a $10 Check

If the buyer had taken just a minute to verify the signature through Signatrue.ai, they could’ve saved themselves a lot of money and frustration.

For just $10, they would have received:

• A detailed, visual report explaining the signature flaws
• A clear authenticity likelihood score
• Confidence on whether to proceed with the purchase — or walk away

This tool is made for exactly this kind of situation — helping fans and collectors avoid buying fake signed items that aren’t worth the paper they’re printed on.

A Seller's Story Isn’t Proof of Authenticity

We’ve seen every excuse and backstory:

• “Signed in person at a private event.”
• “Comes with a certificate of authenticity.”
• “Bought it from a trusted source years ago.”

Unfortunately, most of these claims don’t hold up under proper analysis. Some of the worst fakes we've seen came with the most convincing stories.

That’s why we created Signatrue.ai — so people don’t have to guess anymore. Just upload a photo of the item, and within seconds, you’ll get a full breakdown and an authenticity check that’s based on data — not stories.

Don’t Rely on Luck. Get Proof.

We hate seeing people waste their money chasing fake collectibles. Whether it’s a signed card, jersey, ball, or photo — there’s real value in memorabilia, but only if it’s actually authentic.

Before you buy, take 30 seconds to check with Signatrue.ai. For $10, you could protect a $300 purchase — or more.

✅ How It Works:

1. Upload a photo of the signed item
2. Pay a small fee (starts at $10)
3. Get a full authenticity analysis instantly

Final Thoughts

If the buyer of that $300 Pelé card had checked it first, they almost definitely wouldn’t have bought it. But now? They’re stuck with something that might look valuable, but isn’t.

Don’t make the same mistake.

Whether you're a collector or just a fan, Signatrue.ai gives you peace of mind before you buy. Because when it comes to autographs, guessing just isn’t good enough anymore.
