If you've ever purchased signed sports memorabilia, you've probably noticed a small hologram sticker attached to the item.

These are known as sports memorabilia authentication stickers, and they're one of the most important parts of the authentication process.

Companies like Beckett Authentication Services (BAS), James Spence Authentication (JSA), and PSA/DNA use these holograms to identify and verify authenticated autographs.

Here's what you should know before buying authenticated memorabilia.

What Is an Authentication Sticker?

An authentication sticker is a tamper-evident hologram placed on a piece of signed sports memorabilia after it has been authenticated.

Each sticker contains a unique certification number that identifies that specific authentication.

Many modern authentication stickers also include a QR code that takes you directly to the authentication company's online verification page.

---

What Information Is Stored?

When you scan the QR code—or manually enter the certification number—you should be able to verify the authentication online.

Depending on the authentication company and the type of authentication, the database may include:

• Athlete's name
• Type of memorabilia
• Certification number
• Authentication type
• Date of signing (often for witness authentication)
• Sometimes the signing location

Every certification number should correspond to the item being sold.

---

Why Are Authentication Stickers Important?

Authentication stickers help connect the autograph to the authentication company's online records.

Rather than relying solely on a paper Certificate of Authenticity, collectors can verify the authentication instantly online.

That's one of the reasons modern authentication has become much more reliable than older paper-only systems.

---

Does an Authentication Sticker Guarantee an Autograph Is Authentic?

No.

This is one of the biggest misconceptions in sports memorabilia collecting.

Just because an item has an authentication sticker does not automatically guarantee that the autograph is genuine.

Unfortunately, counterfeit authentication stickers have been produced for nearly every major authentication company.

Many fake holograms originate overseas and are designed to closely resemble genuine Beckett, JSA, or PSA stickers.

Because of this, collectors should never rely solely on the sticker itself.

---

Even Online Verification Isn't Foolproof

Verifying the certification number online is an important step—but it still isn't a guarantee.

Some counterfeiters have copied legitimate certification numbers from authentic memorabilia and recreated fake holograms using those same numbers.

That means the certification number may actually appear in the authentication company's online database while the autograph attached to the item is still fake.

This is why experienced collectors always examine both the autograph and the authentication.

The sticker should support the autograph—not replace careful inspection.

---

Always Examine the Autograph

Before purchasing signed memorabilia, compare the autograph to known authentic examples.

Ask yourself:

• Does the signature look natural?
• Does it match known authentic examples?
• Is the size and slant consistent?
• Does the item itself make sense for that athlete?

The authentication sticker is only one part of the evaluation process.

Why Some Expensive Memorabilia Doesn't Have a Sticker

Occasionally you'll find high-end memorabilia that doesn't have an authentication sticker attached directly to the item.

That isn't necessarily a problem.

For valuable autographs—such as LeBron James, Mickey Mantle, or other premium collectibles—authentication companies may issue a Letter of Authenticity (LOA).

With companies like JSA, collectors often receive:

• A Letter of Authenticity
• A matching authentication sticker

The customer may choose to have that sticker placed directly on the memorabilia or attached to the Letter of Authenticity instead.

Many collectors prefer keeping expensive vintage items free of stickers while maintaining the authentication through the accompanying LOA.

---

Always Verify Authentication Online

Regardless of which authentication company you use, every certification number should be verified online before purchasing.

Trusted companies like:

• Beckett Authentication Services
• James Spence Authentication (JSA)
• PSA/DNA

all maintain searchable online databases.

If a certification number can't be verified, or the information doesn't match the item you're considering, ask questions before buying.

---

Final Thoughts

Sports memorabilia authentication stickers are an important part of the authentication process, but they should never be the only reason you trust an autograph.

Always verify the certification number online, examine the autograph itself, and purchase from reputable dealers who stand behind what they sell.

Authentication stickers are valuable tools—but informed collectors know they're just one piece of the authentication process.
