#1085 What if the old trading cards sitting in your closet could become the start of a six-figure side hustle? In Part 1 of this two-part episode, Brien Gearin sits down with William Butterton and Eric Braun of Pack Daddies to unpack how two longtime friends turned their love of trading cards into a business generating more than $100,000 a year in sales — all while working full-time jobs. William and Eric share how they started selling sports cards on Whatnot, lost money on their early streams, and eventually found traction by pivoting into Pokémon and ’90s nostalgia. They also break down why flexibility and market research have been critical to their growth, the difference between sealed products and singles, and why beginners may be better off focusing on vintage cards and selling in person!
