Authenticity of Powers Sports Memorabilia
When collectors ask, “How do I know this autograph is real?” That is one of the most important questions in the memorabilia hobby. At Powers Sports Memorabilia, we take authenticity seriously because every signed item in your collection should be genuine, verifiable, and supported by trusted authentication.
Authenticity is the foundation of the collectibles market. Because forged memorabilia exists, it is important for collectors to understand how autographs are verified and authenticated. Authentic memorabilia typically includes a tamper-proof hologram that links the item to a legitimate signing or verification process. Paper certificates of authenticity are no longer used, everything is digital now.
What Does “Authentic” Mean?
In sports and celebrity memorabilia, authentic means the signature was signed directly by the athlete or personality it is attributed to. It is not copied, mechanically reproduced, or forged.
Authentication confirms that the autograph was signed by the person listed and helps protect both the integrity of the item and collector confidence.
How Autographs Are Authenticated
Powers Sports Memorabilia guarantees the authenticity of every autographed item it sells. All autographs are authenticated by PSA, JSA, or Beckett, either through third-party witnessing at the time of signing or through independent authentication after the signing.
Professional authenticators verify signatures using expert analysis and comparison to known examples. They evaluate details such as signature style, pen pressure, ink flow, letter formation, and placement.
We work with respected third-party authentication companies, including:
- PSA/DNA
- James Spence Authentication (JSA)
- Beckett Authentication Services
These companies place a unique authentication hologram or sticker directly on the item. This verification number can be checked in the authenticator’s online database.
We also often offer Photo Proof, which allows collectors to purchase a photo of the athlete signing their specific item. To see examples of Photo Proof from past signings, visit our Instagram page, where we regularly share signing photos and behind-the-scenes content.
What You Should Expect With Every Authentic Item
With an authentic autographed item, collectors can expect:
- A unique authentication sticker or hologram when applicable
- A clear description of the signed item and signing event
- Contact or verification information for the authentication company in many cases

I love the service Powers Sports Memorabilia provides. If there is ever any issues or concerns they inform you right away. The ink did not take well to the card but they immediately let me know and I appreciated it. The signature was still a success!

One of my favorite players as a kid watching him compete with Jordan in the slam dunk contest.
Boom! Love it!
The entire process was easy to follow. I had the Johnny bench card in my coo for probably 40 years. It was time to get it signed.
Awesome looking Barry Sanders autograph! The auto came out great on the Panini die cut card! This is a great auto to add to my personal collection! Awesome grade from PSA as well! A big thanks to Powers Sports Memorabilia for a smooth process and for great communication along the way! It's great that you offer such a variety of former and current players for signings. You are also great at promoting your services and being transparent with the whole autograph process. I'd highly recommend Powers Sports Memorabilia for all your autograph needs!
Wonderful work!
