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.
Browse our store, relive some memories, and discover something awesome. Follow us on Instagram for the latest treasures!
