Trusted by Collectors Since 2008
Choosing where to purchase sports memorabilia is about more than just finding the lowest price. Collectors want confidence that they're buying authentic memorabilia from a company with experience, knowledgeable staff, and a proven track record.
Since 2008, Powers Sports Memorabilia has helped collectors across the world build collections featuring authenticated autographs, graded sports cards, game-used memorabilia, and exclusive autograph signings.
Whether you're purchasing your very first signed baseball or adding a rare Hall of Fame autograph to an established collection, our goal is to make the experience simple, transparent, and enjoyable.
Why Thousands of Collectors Choose Powers
Every year we work directly with athletes across multiple sports, giving collectors the opportunity to:
- Send in their own memorabilia
- Purchase newly signed items
- Add inscriptions
- Request authentication
- Have signed cards professionally graded
That means collectors have access to signings they often can't get anywhere else.
Many of our autograph signings offer witness authentication from trusted third-party companies such as:
- PSA Authentication
- Beckett Authentication Services (BAS)
- James Spence Authentication (JSA)
These companies witness the athlete signing the memorabilia before applying their authentication sticker.
We also educate collectors about authentication so they understand exactly what they're buying.
