Sports memorabilia authentication helps collectors buy and sell signed memorabilia with greater confidence—but there are still plenty of myths surrounding how authentication actually works.
Many collectors assume that an authentication sticker guarantees an autograph is genuine or that an item appearing in an online database means it's impossible for it to be fake.
Unfortunately, it's not that simple.
Here are some of the most common sports memorabilia authentication myths and the truth behind them.
This is probably the biggest misconception in the hobby.
An authentication sticker from Beckett, JSA, or PSA is an important part of the authentication process, but it is not a 100% guarantee that an autograph is genuine.
Counterfeit authentication stickers have been produced for every major authentication company.
Some fake holograms are remarkably convincing, which is why experienced collectors never rely solely on the sticker.
Always examine the autograph itself and verify the authentication online.
Another common misconception is that if you scan the QR code and the certification number appears in the authentication company's database, the autograph must be authentic.
Unfortunately, counterfeiters have copied legitimate certification numbers from authentic memorabilia and reproduced fake authentication stickers using those same numbers.
That means a certification number may appear online while the autograph attached to the item is not genuine.
The online record should always support your evaluation of the autograph—not replace it.
Many collectors expect an authentication record to appear online as soon as the autograph is authenticated.
In reality, that's often not the case.
For example, after an autograph signing, the authenticator must submit the certification information to the authentication company.
That information then has to be reviewed, processed, and uploaded to the online database.
Depending on the company and its workload, this process may take several weeks.
If a newly authenticated autograph isn't immediately searchable online, it doesn't automatically mean there's a problem.
Authentication companies employ experienced experts, but they're still human.
With opinion-based authentication, companies compare the autograph to known authentic examples by evaluating characteristics such as:
Based on that evaluation, they provide their professional opinion.
Because it's an opinion, mistakes can happen.
No authentication company is correct 100% of the time.
Witness authentication is generally considered the strongest form of autograph authentication because a representative from the authentication company is physically present while the athlete signs the item.
However, that doesn't mean counterfeiters haven't attempted to copy witness authentication stickers.
Fake witness holograms have also appeared in the marketplace.
That's why collectors should still verify certification numbers online and carefully inspect the autograph and the memorabilia.
Authentication is extremely important—but it shouldn't be the only thing you evaluate.
You should also ask yourself:
Authentication is one piece of the puzzle, not the entire puzzle.
Sports memorabilia authentication is an incredibly valuable tool for collectors, but understanding its limitations is just as important as understanding its benefits.
Authentication stickers, QR codes, and online databases all provide additional confidence—but none of them should replace careful research and common sense.
The best collectors use authentication as one part of a complete evaluation before purchasing signed sports memorabilia.
No. Authentication stickers are an important security feature, but counterfeit stickers do exist. Always inspect the autograph and verify the certification online.
It may simply be waiting to be processed. New authentications can sometimes take several weeks to appear online.
Yes. Opinion-based autograph authentication is exactly that—an expert opinion based on comparisons to known authentic signatures. Even experienced authenticators can occasionally make mistakes.
Witness authentication is generally considered stronger because an authenticator observes the item being signed. However, collectors should still verify the authentication and examine the autograph.
No. Online verification is important, but it should be combined with examining the autograph itself and buying from a reputable seller.

Once again, Powers Sports came through big time! I had been waiting for many, many years to have this mini helmet signed by Carson Palmer. With special thanks to Natalie and Mathew, they were able to coordinate this endeavor exactly as I wanted it. Excellent autograph, perfectly positioned, using the exact paint pen requested and the C.O.A. sticker positioned right where I wanted it. Thank you folks so very much!

Everything at Powers is first rate. They posted the videos on Facebook so I actually got to watch LT sign my helmet. And then they shipped me my helmet it's perfect could not be happier.
