    The WNBA Card Podcast: Collecting the Seattle Storm — The Cards That Carry the History with Jenny (@wsportscollector)

    Katelyn (@coldlunchcards) sits down with Jenny (@wsportscollector) to explore her Seattle Storm collection. Jenny shares how moving to Seattle during the 2020 championship season connected her to the team. She explains why she narrowed her collection, how she chooses cards, and why eye appeal matters more than a serial number. They also discuss Sue Bird, Lauren Jackson, Breanna Stewart, Jewell Loyd, the Storm’s next generation, and the opportunity to collect a team during a rebuild. Jenny tells the story of winning Panini’s WNBA Player of the Day promotion and opening cards alongside Cynthia Cooper. She closes with the Sue Bird rookie relic containing material from Bird’s first WNBA game and the ticket she paired with it. This is a conversation about team collecting, community, and owning pieces of the history that made you care.

    Passion to Profession: Finding the Unfindable — How Grant Slayton Built His Business

    Grant Slayton has built Waldorf Stories by finding cards most collectors never see and connecting them with people who value them. That reputation took years to earn. Grant joins Brett to explain why trust sits at the center of his business, how he approaches trades, and why relationships matter more than any single transaction. They discuss the five-and-a-half-year pursuit of the 1997 Ultra Michael Jordan Platinum Medallion 1/1, the work behind sourcing rare cards, and how Grant decides when a card means more than its market value. Grant also shares his advice for anyone who wants to turn cards into a profession. Help enough collectors get what they want, and the next opportunity often finds you.

    The Football Card Podcast #63: Who Decides a Player's Defining Card?

    What makes one card the defining card of a player? The rookie label? Market value? Recognition? Rarity? Pack and Brett challenge the belief that a player’s rookie card must be his best card. They use the $240,000 Patrick Mahomes Topps Chrome Superfractor and his $195,000 Prizm Gold Vinyl rookie to test where they stand. They also make their NFL division and Super Bowl picks, consider what the Topps era means for Panini case hits, and review sales of Caleb Williams, Jaxson Dart, Randy Moss, and Tom Brady. Plus, they share how fathers can watch football without losing the rest of their Sunday.

    One Sale Is Not the Market: How Collectors Should Read Thin Markets

    A landmark card sale creates attention. It also creates assumptions. The 2025 Topps Royalty John Cena WrestleMania Patch Autograph 1/1 has reached six figures with time left in the auction. What does that number tell us about Cena cards, wrestling cards, and other markets where sales data is thin? Brett breaks down the difference between a signal and a comp, introduces the evidence ladder, and shares a process collectors can use before buying, selling, or repricing a card. One sale can be historic without becoming universal.

    The Hobby You Have Now Rewards the Proactive Collector

    The hobby has changed. Prices have risen. More cards compete for your attention. Every sale becomes content. It is fair to miss what collecting used to feel like. But the hobby we have now gives collectors access to sales history, checklists, population reports, saved searches, auction archives, and people with years of knowledge. Access is no longer the edge. Judgment is. Brett explains why the modern hobby rewards proactive collectors and shares a system for making decisions with purpose. Build a collecting thesis. Assign a role to each source. Monitor the cards that matter. Record why you buy. Give yourself confidence to pass. The hobby you remember is not coming back in the same form. That does not mean your best collecting years are behind you. Check out the awesome software that InfernoRed Technology can build for you.

    The WNBA Card Podcast: Collecting the Washington Mystics’ New Era with Matthew (@dynastysportscards_)

    Matthew (@dynastysportscards_) followed Georgia Amoore from college basketball to the Washington Mystics. That connection grew into season tickets, a family business, and a collection centered on the players he watches each week. Matthew joins Katelyn (@coldlunchcards) to discuss the Mystics’ young core, the link between attending games and collecting cards, Shakira Austin’s place on the hobby’s Disrespect Index, and the cards that define his collection. He also shares the story behind his personal grail. It is not his rarest card. It is a Sonia Citron Pink Laser auto /25 that he pulled with his daughter during a hard season for their family. Some cards matter because of what they are. Others matter because of where you were and who was beside you when you found them.
