Authenticity Guarantee
100% Authenticity Guarantee
Authentic Autographs. Trusted Authentication. Lifetime Confidence.
Every autographed collectible sold by Gameday Sports & Memorabilia is backed by our Lifetime Authenticity Guarantee.
We work with established authentication providers and documented signing programs, including Beckett Authentication Services (BAS), James Spence Authentication (JSA), PSA/DNA, Fanatics Authentic, Schwartz Sports, MLB Authentication, and Grad Authentication (Grad Witness).
Depending on the item and authentication provider, your memorabilia may include a serialized hologram, witnessed authentication label, digital authentication record, certificate of authenticity (COA), letter of authenticity (LOA), or other supporting documentation.
Our Lifetime Promise
If an autographed item purchased from Gameday Sports & Memorabilia is determined to be inauthentic by a recognized independent authentication provider, we stand behind our guarantee with a full refund of the original purchase price, subject to verification of the claim.
Shop with confidence knowing that authenticity is at the heart of everything we sell.
Why Authenticity Matters
The value of sports memorabilia begins with trust. When you purchase an autographed jersey, football helmet, photograph, or other signed collectible, you deserve to understand how its autograph was authenticated.
That's why we prioritize memorabilia supported by established authentication providers and documented signing programs.
- Established autograph authentication providers
- Authentication details available for each item
- Serialized identification where applicable
- Digital or physical supporting documentation
- Assistance with authentication questions
- Our Lifetime Authenticity Guarantee
Our guarantee covers the authenticity of the autograph. It does not mean that a jersey is officially licensed or that a helmet was worn during an NFL game unless those details are specifically documented.
How Autograph Authentication Works
Authentication methods vary by provider and collectible. Here's what you can generally expect when purchasing authenticated memorabilia.
Professional Authentication
We source autographed memorabilia supported by established authentication providers and signing programs. Depending on the item, authentication may involve witnessing the signature or examining it after signing.
Authentication Identification
Many collectibles feature a serialized hologram, QR code, or other identifying information. The exact format depends on the provider and its authentication program.
Supporting Documentation
Your item may be supported by a digital record, physical COA, letter of authenticity, or documentation associated with an authorized signing event.
Verification
Where an online verification service is available, you can check certification details through the provider's website. We can also help answer questions about the documentation supplied with your purchase.
Grad Witness: In-Person Autograph Authentication
Some of our autographed sports memorabilia is authenticated through Grad Witness, an in-person autograph authentication service offered by Grad Authentication.
Unlike traditional third-party authentication, which may involve examining an autograph after it has been signed, Grad Witness authentication occurs at the time of signing. A Grad Authentication representative personally witnesses the autograph, providing documented confirmation of its origin.
Items authenticated through Grad Witness feature a unique certification sticker and an associated digital authentication record.
How to verify a Grad Witness autograph:
-
Locate the Grad Authentication certification sticker on your memorabilia.
-
Visit the official Grad Authentication Certificate Lookup.
-
Enter the certification information to review the available authentication record.
Additional documentation, such as a verification letter or signing photographs, may be available for certain items.
Like all autographed memorabilia sold by Gameday Sports & Memorabilia, Grad Witness-authenticated collectibles are backed by our Lifetime Authenticity Guarantee.
Verify Your Autographed Memorabilia
Many authentication providers offer online tools for reviewing certification information. Locate the hologram number, certificate number, or other identifying information associated with your collectible, then select the appropriate provider.
Important: A matching certification record is a valuable verification step, but it is not conclusive proof of authenticity by itself.
Always consider the item, its documentation, and the credibility of the seller and authentication provider.

Frequently Asked Questions
Do all autographed items include a COA?
Authentication documentation varies by provider. Some collectibles include a physical certificate of authenticity, while others use serialized holograms, digital records, letters of authenticity, or signing-program documentation. Review the product description for details.
What if I lose my Certificate of Authenticity?
If your item has a serialized hologram or digital authentication record, you may still be able to review its certification information. Replacement documentation depends on the authentication provider. Contact us with your order number and photographs if you need assistance.
Can I verify my autograph years after purchase?
Many established authentication providers maintain searchable certification records. However, record availability and online verification services are controlled by each provider and cannot be guaranteed indefinitely.
How does Beckett QR code authentication work?
Many Beckett-authenticated collectibles feature a serialized authentication label with a QR code. You can scan the code or enter the certification number on Beckett's official verification website to review the available authentication record.
Authentication formats can vary depending on the item and when it was certified. Some Beckett items may also have physical documentation.
Can a replica football helmet have an authentic autograph?
Yes. A replica football helmet can feature a genuine, authenticated autograph. The term "replica" describes the helmet's construction and display purpose, not whether the player's signature is authentic.
Read our Authentic vs. Replica Helmets Guide to learn more.
Are custom autographed jerseys authentic?
Yes. A custom jersey can carry a genuine autograph even when the jersey itself is not officially licensed by the NFL or another sports league.
Autograph authenticity and jersey licensing are separate considerations. Review the product description to understand exactly what you're purchasing.
Learn more in our Custom Autographed Jerseys Guide .
Does a matching hologram number guarantee authenticity?
A matching certification record is an important verification step, but it is not definitive proof on its own. Certification numbers and labels can potentially be copied, so the item and its documentation should be evaluated together.
What if I believe my autograph is inauthentic?
Contact our customer service team with your order number, photographs, and any available authentication findings. We'll review the information and help you through the guarantee process.
Are unsigned products covered by this guarantee?
Our Lifetime Authenticity Guarantee specifically covers autographed items. Non-autographed merchandise is subject to our standard return policies.
