    Card Ladder Confidential #23: What the Market Cannot Price

    17/09/2026 | 59 mins.
    What gives a card value when no comparable sale can explain why it matters to you?
    Chris McGill and Josh Johnson join Brett for a conversation about what the market cannot price.
    They discuss the owner’s price, replacement difficulty, the appeal of one-of-ones, and the difference between following the market and building your own card hierarchy.
    Josh shares why he bid $27,000 on a Todd Gurley card that he won for $4,000. Chris explains the history behind his 1998 Topps Gold Label Wayne Gretzky one-of-one and why he regrets selling parts of his Christian McCaffrey collection.
    Price data matters. It gives collectors context. It does not measure what a card completes, what it took to find, or how losing it would change your collection.
    This conversation is about using market data without letting the market make your decisions for you.

    The Honor of Ownership: When Keeping the Card Is the Point

    16/09/2026 | 27 mins.
    The hobby spends a lot of time talking about how cards enter collections and how they leave.
    We talk about the chase, the deal, the grade, and the sale.
    We skip the years when the card is yours.
    In this episode, Brett explores what ownership gives collectors beyond market value. He shares the story behind four T.Y. Hilton Prizm Black Finite 1/1s and examines how time, knowledge, memory, and relationships deepen our connection to cards.
    Keeping a card is not always the absence of a decision.
    Sometimes, keeping the card is the point.

    Passion to Profession: Employee No. 12 — Building Overtime and Its Trading Cards with Sam Gordon

    14/09/2026 | 52 mins.
    Sam Gordon had accepted a job on Wall Street.
    Two weeks before he was set to start, he walked away and joined Overtime as its 12th employee. The company had a few months of funding left.
    Today, Sam serves as VP of Programming and Head of YouTube at Overtime.
    Sam shares how $15 videos of Zion Williamson reached SportsCenter, why Overtime chose speed over production quality, and how the company grew from a social media account into a sports league.
    We also get the collector’s view of building the Topps OTE card products.
    Sam explains the push for on-card autographs, rookie logos, card backs written in Overtime’s voice, and the production demands that led to stickers and redemptions.
    He also tells the story of turning a Lionel Messi Superfractor autograph pulled from a box at work into his favorite card, a 1999 Michael Jordan Final Floor autograph.
    This is a conversation about trusting people, testing ideas, building with ownership, and creating sports cards from the collector’s seat.
    Passion to Profession is presented by eBay.
