    The WNBA Card Podcast: Why Team Collecting Makes the Hobby Better | Griff's (@rockyscardboard) New York Liberty Collection

    07/07/2026 | 1h 23 mins.
    The best collections start with connection.
    In this episode, Katelyn is joined by Griff (@rockyscardboard), one of the hobby's most respected WNBA collectors and a passionate New York Liberty fan.
    They discuss how Liberty fandom shaped his collection, why Sabrina Ionescu became a cornerstone of his PC, and how buying, selling, and collecting all work together to create a more rewarding hobby experience.
    The conversation also explores eye appeal, collector psychology, the thrill of the chase, and why building relationships often matters as much as building a collection.
    Whether you're a team collector, player collector, reseller, or somewhere in between, this episode offers a thoughtful look at what keeps collectors coming back.

    Passion to Profession: Relationships Compound Faster Than Transactions with Mike from MC Sports Cards

    07/06/2026 | 45 mins.
    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.

    Hobby Jobs: Ryan Johnson on Building a Sports Card Company That Lasts

    07/05/2026 | 42 mins.
    Product knowledge gets you in the door.
    Systems determine how far you go.
    In this episode of Hobby Jobs, I break down why the next generation of sports card businesses will be built on repeatable processes instead of founder instinct alone.
    The hobby is getting bigger. Companies are hiring. Events are growing. Expectations are changing. That means the operators who build training, marketing, hiring, customer experience, and operating systems will have the edge.
    Then I sit down with Ryan Johnson of Cardcollector2 live at Columbus Card Fest.
    Ryan shares what it has been like to grow from a collector and content creator into the leader of a company with nearly 40 employees. We talk about launching Columbus Card Fest, building teams, making hiring decisions, balancing content with company building, and why people have become his biggest investment.
    Whether you already work in the hobby or want to build your career here, this conversation offers a look at where the industry is headed and what skills will matter most.
    Product knowledge helps you start.
    Systems help you scale.

    The Football Card Podcast #54: Remembering the Greatness of Chris Johnson

    07/03/2026 | 1h 19 mins.
    Chris Johnson reminded football fans why collecting is about more than championships.
    After sharing his ALS diagnosis, collectors looked back at one of the most electric careers of the last 20 years. Pack and Brett revisit what made CJ2K special, why his cards matter, and why memorable seasons leave a lasting mark on the hobby.
    The conversation then shifts into one of the biggest collector debates today.
    Will vintage football cards ever break through? Why are Topps Chrome Superfractors selling at such a premium compared to Black Finite cards? And why do the biggest sales often come from patch autos while so many collectors chase shiny parallels?
    Also in this episode:
     The greatest No. 54 linebackers 
     Bobby Wagner and Chuck Howley appreciation 
     Why football history feels overlooked 
     Wide receiver 1/1 sales from Card Ladder 
     National preparation and collector strategy 
    If you collect football because of the players and the memories they created, this episode is for you.
