Authenticity
Authenticity isn’t just a promise
It’s part of who we are. Every item we sell that requires verification comes with a certificate direct from the athlete or artist, or from a respected third-party authentication company.
Why authenticity matters
Fans and collectors everywhere want to own a real piece of history, whether it’s a signed shirt, a race-used glove, or a limited-edition print.
But with that demand comes risk. Forgeries and unverified items have become more common, making trust more important than ever.
At Wisbys, we believe knowing your item is genuine is not just reassuring, it’s essential.
When you buy from us, you’re not just getting a product.
You’re investing in the legacy behind it.
We built Wisbys on integrity, authenticity, and creating value for collectors. Every piece we offer is chosen to inspire, to preserve moments of greatness for the next generation, and to strengthen the community of fans who care about real stories and real history.
What a certificate tells you
A Certificate of Authenticity is your proof that an item is what it claims to be. It’s the industry standard for verifying that a signature or game-used item is genuine.
Who issued it
A certificate direct from the athlete or artist, or from a respected third-party authenticator.
That it matches the piece
A certificate is only useful if it genuinely matches the piece, so we check the documentation aligns with the item being sold.
A serial you can look up
Serial-numbered stickers and online certification let you check the record yourself.
Value if you ever resell
A respected certificate helps ensure the item’s value is preserved and its authenticity isn’t questioned.
The authenticators we trust
We work with and recognise certificates from some of the most respected companies in the industry. No certificate is 100% infallible, but requiring proper certification means you’re buying with the best safeguards available.

No two signatures are the same
Even genuine signatures vary. Athletes and artists change their signature over time, sign quickly under pressure, or adjust to the surface they’re signing.
That’s part of what makes collecting interesting, and why relying on experts who know what to look for is so essential.
Keep an eye on our socials for detailed explanations of the different certificate types, the key tells of a suspect signature, and more to help you collect safely.
