Passion to Profession: Preserving the Hobby's Legacy with Integrity with Michael Osacky of Baseball in the Attic

Stacking Slabs

In this episode of Passion to Profession, Brett sits down with Michael Osacky from Baseball in the Attic, one of the most trusted voices in sports memorabilia appraisal. Michael shares stories from the road, from emotional appraisals in small-town basements to unexpected discoveries in forgotten collections.

They talk about the current state of the appraisal business in 2025, the rise in institutional requests, fraud detection, and what collectors often overlook when it comes to storage, insurance, and preservation.

Michael opens up about delivering tough news, maintaining integrity in a business full of bias and emotion, and why relationship-building matters as much as expertise.

This one is a must-listen for anyone who collects, buys, sells, or simply wants to protect what matters most.
