Gameboyz – Curators of Nostalgia & Premium Collectibles
Welcome to Gameboyz, where we specialize in rare and high-end entertainment collectibles—sports memorabilia, autographs, video games, TV props, and more. Simply put: we buy and sell nostalgia.
Collecting runs in the family. It all started with my dad, former San Francisco Giants catcher Mike Sadek, whose passion for coin collecting and the *thrill of the hunt* inspired me. In the '80s and '90s, we built a collection of baseball cards and memorabilia, a tradition I now share with my own three sons. Over time, our interests have expanded to include video games, vinyl records, comic books, Breaking Bad props, and other unique finds.
