In this episode of Passion to Profession sponsored by eBay, Mike Brown from 4 Sharp Corners joins the show to take you inside one of the most trusted operations in the hobby.

We sit down to talk about growth, decision making, and why the right processes build trust.

Mike shares how he moved from finance into cards, what he learned from working alongside Stan and Roger, and why focus keeps their business moving in the right direction.

You’ll hear how they built their consignment division from the ground up, the impact of Probstein leaving eBay, and why their select showcases have changed how collectors think about selling big cards.

If you want a better view of where the hobby is headed and how top sellers think, this episode gives you an honest look under the hood.

A special thank you to eBay for sponsoring Passion to Profession. The biggest and best marketplace to buy your next favorite trading card.
