The best businesses in the hobby are not built one deal at a time.

They're built one relationship at a time.

Mike from MC Sports Cards returns to Passion to Profession to share why trust has become the foundation of one of the fastest-growing consignment businesses in the hobby.

We talk about what happens after the first transaction, why honesty wins over short-term revenue, how technology should support relationships instead of replace them, and why saying no has become one of the most important decisions in growing the business.

We also discuss the growth of high-end cards on eBay, what serious collectors expect from a consignment partner, how MC Sports Cards approaches customer service at scale, and why every interaction is an opportunity to earn another one.

Whether you're building a collection or building a business, this conversation is a reminder that reputation compounds.

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