Great experience once again! From start to finish Powers Sports Memorabilia hit it out of the park on my Ricky Williams Newpapers.
What Is Witness Authentication at an Autograph Signing?
Learn how witness authentication works at autograph signings, why it's important, and how PSA, Beckett, and JSA verify autographed memorabilia.
If you're participating in an autograph signing, you'll often have the option to add witness authentication to your order.
For many collectors, it's one of the most important parts of the signing process.
Witness authentication provides independent verification that your memorabilia was actually signed by the athlete during the autograph signing.
Here's exactly how it works.
What Is Witness Authentication?
Witness authentication means a representative from an authentication company is physically present at the autograph signing while the athlete signs your memorabilia.
Because the autograph is witnessed in person, there is no need for the authentication company to examine the signature afterward.
They personally observe the signing as it happens.
Who Performs Witness Authentication?
The three most widely recognized authentication companies that regularly attend autograph signings are:
- PSA
- Beckett Authentication Services (BAS)
- James Spence Authentication (JSA)
Depending on the signing, one of these companies may witness the event and authenticate every eligible item.
How Witness Authentication Works at an Autograph Signing
The process is straightforward.
- Your memorabilia is prepared for the signing.
- The athlete signs your item.
- An authentication representative watches the signing.
- A witness authentication sticker or hologram is placed directly on your memorabilia.
- Your item receives a unique certification number.
This certification connects your memorabilia to an official authentication record.
Why Does the Sticker Go on the Item?
For witness authentication to be valid, the authentication sticker or hologram must be attached directly to the signed memorabilia.
This permanently links the authentication record to that specific item.
If you're sending your own memorabilia, you can usually indicate where you'd prefer the authentication sticker to be placed.
How to Verify Your Witness Authentication
After the signing, you can verify your authentication online.
Simply enter your certification number on the authentication company's website.
Some companies, such as Beckett, also include a QR code that takes you directly to the verification page.
Depending on the company, you'll often see information such as:
- Athlete's name
- Authentication number
- Date of the signing
- Description of the item
Is Witness Authentication Required?
No.
Authentication is optional for many autograph signings.
However, many collectors choose it because it provides independent documentation that the autograph was witnessed by a professional authentication company.
Witness Authentication at Powers Sports Memorabilia
Most of our autograph signings offer witness authentication through PSA, Beckett Authentication Services (BAS), or James Spence Authentication (JSA).
If you purchase Our Item, witness authentication is typically included.
If you're sending Your Item, you can add witness authentication during checkout whenever it's available for that signing.
After the signing, your memorabilia will include the authentication sticker or hologram along with a certification number that can be verified online.
Final Thoughts
Witness authentication is one of the most trusted ways to document an autograph obtained during an autograph signing.
Because an authentication representative personally observes the athlete signing your memorabilia, collectors can have added confidence that the autograph is genuine.
If witness authentication is available for your signing, it's an excellent option for collectors who want independent verification and an online authentication record.

Awesome experience as always, I’d highly recommend Powers to anyone looking to expand their sports memorabilia collection!
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!
Matt and his team did a great job as usual. I highly recommend power’s!
Always great dealing with Powers. Got to watch Earl Singing on their website. Couldn't be happier with the helmet and the signature. Another perfect purchase. Thanks Powers crew!
I submitted 2 cards for signing by Dennis Rodman and came back very nice but one of the cards corner was damaged when returned back. Thank you Matt Powers and his team for this signing event.
I submitted 2 cards for signing by Hakeem Olajuwon & came back very nice. Thank you Matt Powers and his team for this signing event.

PSM never let's me down. Another great auto on my multi signed piece. Thank you again.
The Barry Larkin auto in my PC is pure heat. Crisp ink, great placement, total keeper.
Just received by Bo Jackson Rookie Card back from Powers Sports Memorabilia. Once again, Powers Sports was able to get my card signed exactly as requested. Excellent signature, perfectly positioned and using the right kind and color marker.
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.
