    '90s Demand Is Different: Josh Adams on PMGs, Patience, and Playing the Long Game

    2/12/2026 | 44 mins.
    What is really happening in the '90s category right now?

    Josh Adams from 90s Auctions joins me to break it down. We talk about healthy growth, why some grails spike and then cool off, and what collectors misunderstand when they look at big comps in isolation.
    We unpack the recent 1998 Metal Universe Peyton Manning PMG sale and why the PSA 8 brought $24K while BGS copies trailed far behind. Is it a PSA premium? Timing? Platform? Or something deeper about collector cards versus commodity cards?
    Josh shares how he thinks about patience, consolidation, and why he stops checking comps once a card hits his PC. We also walk through key pieces from his collection, including a 1998 PMG Frank Thomas, 1997 Diamond Dimensions Jordan, and a 1997 Essential Credentials Future Jordan he consolidated heavily to land.

    If you care about scarcity, availability, and building a collection that lasts, this one is for you.

    Scarcity Is About Who Owns the Card

    2/11/2026 | 25 mins.
    Scarcity in sports cards is not a print run problem. It is an ownership problem.

    In this flagship episode, I break down why some cards feel impossible to find while others never stop circulating. The difference is not how many exist. The difference is who owns them and whether they sell. Using real examples from modern, 90s, and vintage cards, Brett walks through how ownership concentration, churn, and collector behavior shape what scarcity feels like in the market.

    If you want to slow down, stop overpaying for hype, and build a collection with intention, this episode gives you a new lens. One that helps you ask better questions before you spend your money and chase the next card.

    The Staging Area #18: First to Market, First to Matter

    2/10/2026 | 43 mins.
    January set a record. $445M in online sales across the hobby. Tory from dcsports87 felt it firsthand with $14M in sales in one month and no slowdown in sight.
    This episode lives at the intersection of data, demand, and decision making. We break down what record volume looks like inside one of the largest eBay sellers in the world, why first public sales still shape collector behavior, and how a Tiger Woods party exclusive card became a $27,600 moment of cultural debate.
    We also get into live selling at the Super Bowl, why starting a $40K card at $1 works when the audience is right, and what it means for collectors when platforms like eBay push live formats to the front of the app. This is a look at the hobby from The Staging Area before the action hits the field.

    Passion to Profession: Trust Is the Operating System of a Hobby Business with Sharon (BlackJadedWolf)

    2/09/2026 | 41 mins.
    Trust is not a marketing tactic. It is the foundation.

    In this episode of Passion to Profession, I sit down with Sharon of BlackJadedWolf to talk about what it takes to build a hobby business that lasts. We get into what she’s seeing in the market right now. Repacks. Comps that don’t tell the full story. Where liquidity is real and where it is fragile.

    Sharon shares how she thinks about responsibility when customers hand her cards that carry real value. Sometimes financial. Sometimes emotional. We talk about why data is a starting point and not a decision-maker. Why research still matters. Why relationships matter more.

    This is a conversation about independence. About accountability. About playing the long game in a hobby that often rewards short-term thinking.

    This episode is sponsored by eBay.

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

    The WNBA Card Podcast: The WNBA Finds Its Icons — Bird, Taurasi, and the Superstar Era with Elodie (@egintz5)

    2/08/2026 | 43 mins.
    This episode moves the WNBA Card Podcast into the early 2000s, when Sue Bird and Diana Taurasi reshaped how fans connected to the league and how collectors thought about WNBA cards. It was a time defined by team-first collecting, limited media coverage, and cards that reflected presence and performance rather than profit.
    Katelyn is joined by Elodie (@egintz5), a collector from France whose Sue Bird collection is built on commitment and distance. They talk through early card design choices that still matter today, including first game jersey cards, rookie redemptions, and on-card autos from an era before overproduction.
    The conversation widens to international collecting and the reality of building a collection without local card shops. Long shipping timelines, US mailboxes, and community built through trust. It is a reminder that WNBA cards travel far beyond the league’s borders and that players like Sue Bird and Diana Taurasi became anchors for collectors who stayed for the love of the game.
