Meet the biggest Ken Griffey Jr. collector in the world

Jason Vass has built one of the most incredible Ken Griffey Jr baseball card collections in the world, over 150,000 cards, plus rare memorabilia that spans decades of baseball history. But this story isn’t just about the scale of the collection. It’s about why it exists. In this episode of I Collect, Jason walks us through his life’s work., From rows of 1989 Topps Traded rookies to rare refractors and one-of-a-kind pieces, every part of the collection reflects a single focus: Ken Griffey Jr. But behind that focus is something deeper. Jason connected with Griffey not just as a player, but as a person. Griffey’s story of perseverance and growth resonated with him at a young age, and that connection shaped the way he approached collecting and life. What started as chasing cards became something more meaningful: structure, purpose, and a positive outlet through difficult moments. Today, Jason doesn’t collect baseball cards for value or recognition. He collects what he loves. He organizes, logs, and builds his collection with intention, using it as a way to stay grounded. Some of his most meaningful cards aren’t the rarest, they’re the ones tied to moments, like the Griffey refractor his grandmother found at a yard sale, a card that changed everything for him. Beyond the collection, Jason has become a voice in the hobby. He gives baseball cards to kids, supports new collectors, and reminds people that there’s no “right way” to collect as long as it makes you happy. This is a story about passion, discipline, and finding something that gives you purpose. Because for Jason, collecting isn’t about what you own. It’s about what it gives you. 0:00 Intro 0:38 Griffey Vending Machine 1:14: Organization Station 2:17: Why Ken Griffey Jr.? 3:38: Hardest Card to Find 4:48: Yard Sale Grail #sportscards #cardcollecting #baseball #toppsbaseballcards #kengriffeyjr #baseballcards Subscribe if you love collecting!
