What are basketball autograph events?

Basketball autograph events give collectors the opportunity to have memorabilia signed by NBA players, Hall of Famers, and basketball legends through professionally organized private signings.

Private autograph events often allow collectors to submit their own memorabilia, request inscriptions, and receive third-party authentication without attending the event in person.

What basketball memorabilia can I submit?

Most events accept basketballs, jerseys, photographs, trading cards, sneakers, mini basketballs, Funko Pops, ticket stubs, and other approved basketball collectibles.

Yes. Many basketball autograph events allow collectors to purchase memorabilia from Powers Sports Memorabilia and have it signed during the event.

Are the autographs authenticated?

Many of our basketball autograph events include authentication from respected companies such as PSA/DNA, Beckett Authentication Services, or James Spence Authentication.

Can I request autograph inscriptions?
