    Passion to Profession: Selling Cards Without Pressuring Collectors with Collins Boyce

    09/28/2026 | 49 mins.
    Collins Boyce has built Curated Cards and Collectibles across card shows, a store, and eBay Live. The part that stayed with me was how he treats the person buying the card.
    On his live streams, you can talk cards all day and leave without buying one. When a card sells for less than he expected, he tells the buyer, “Great take.”
    Collins and I talk about what he learned from working alongside a shop owner, why he joined forces with a business partner, and how his team decides where each card from a collection should sell. We also get into Ken Griffey Jr. PSA 10s, what a past sale misses when supply is thin, and why losing money on one card can still make sense for the collection.
    This is a conversation about building a card business with systems behind it and room for collectors to collect.
    Passion to Profession is brought to you by eBay.

    Hobby Jobs: What Makes a Collector Come Back? John Amendola on Building Mintink

    09/27/2026 | 1h 2 mins.
    A collector walks into a card shop for the first time. What happens there determines whether they want to return.
    I talk with John Amendola, founder and CEO of Mintink, about how he thinks through that visit. We get into greeting people without pressuring them, making room for kids and parents, training staff as Mintink grows, and listening when someone has a bad experience.
    John says the first sale is easy. The harder question is whether collectors feel enough connection to come back and tell someone else about the shop. This conversation is about the decisions behind that feeling.

    Booked to Last: John Cena’s $329,400 Card, the Rhea Ripley Sale, and Tim Bonito’s WWE Collection

    09/26/2026 | 1h 45 mins.
    John Cena’s WrestleMania patch auto sold for $329,400. Ryan bid on it, set his limit, and watched someone else take it home. He won the Rhea Ripley WrestleMania patch auto in the same auction.
    Adam and Ryan talk through both sales and why one result can’t tell you what every wrestling card is worth. They also look at WWE Stadium Club, Panini redemptions, and a question every collector faces when a product releases: buy the card now, or wait for more copies to surface?
    Then Tim Benito of CardVault by Tom Brady joins the show. He shares how he became the Bron Breakker collector, why he began collecting Undertaker cards, and the one Brock Lesnar Kaboom PSA 10 he still needs to finish his set.

    The Football Card Podcast #66: What Would You Collect If Instagram Disappeared?

    09/25/2026 | 1h 35 mins.
    A collector asks a question that stays with Pack and Brett: If prices, posts, and other people’s opinions disappeared, what football cards would you still want?
    They talk about the difference between buying because a card is available and collecting because you know why it belongs with you. They also look at overlooked football cards from the 1990s, including two 1/1s that sent them searching through sets they knew little about.
    Plus, listener collections, team collecting, Jalen Hurts, and recent sales of Tom Brady, Bo Nix, Tony Romo, Brett Favre, and Troy Polamalu cards.

    Before You Buy the Card, Build the Thesis

    09/24/2026 | 31 mins.
    Why does this card belong in your collection?
    A buying thesis gives you an answer before emotion, scarcity, and outside opinions take control.
    Brett explains the six parts of his process: the personal case, card case, market case, price case, ownership case, and risk case. He applies the process to his purchases of the Roman Reigns Immaculate 1/1, John Cena Superfractor 1/1, and Tyrese Haliburton Crown Royale 1/1.
    A thesis cannot predict the future. It helps you understand the decision, accept the tradeoffs, and live with the outcome after the excitement wears off.
