  • Good but some shows are colts (etc.) fan boy shows

    It’s not my podcast so can do what you want as publisher but some shows are just way too focused on colts. Football card podcast is like a bears colts show that gets tiresome. And really the explicit language is not really needed. Immaturity maybe.

  • Good pod but needs diversity

    Lots of good insightful card talk, but leans too heavily into Colts and WNBA. I understand that it’s the way you hobby, but as someone that doesn’t care about either it can be a drag. Shows how good it is though considering I’ve stuck through it despite the lack of connection I have to those spaces.

Talking Points

Recent interactions between the hosts and their guests.

Booked to Last #10: WrestleMania Shockwaves, Topps Chrome First Day Issue, and Wrestling Card Shop Owner Chad Weldon Joins the Show
Q: Out of all your years ripping, what is your favorite hands-down product to rip of all time?
Chad names 2022 Select as one of his favorite rips, cites the thrill of Mezzanine parallels, and contrasts later prisms and auto-heavy sets with the earlier joy of ripping one-of-one memorabilia; he also notes the rapid price movement and challenges of chasing those hits.
Booked to Last #10: WrestleMania Shockwaves, Topps Chrome First Day Issue, and Wrestling Card Shop Owner Chad Weldon Joins the Show
Q: Tell everybody a little bit about Sports Card Junction and how you got into the hobby.
Chad explains that he started in 1995 when his parents opened the store outside of Pittsburgh, began running day-to-day operations in 2015, and grew into a shop that offers singles, sealed wax, and supplies, while maintaining a deep personal collecting interest in wrestlers like Gunther and LA Knight.
The Football Card Podcast #37: Only 3 Football Cards in 54 Six-Figure Sales… What Does That Tell You?
Q: Do standout seasons make you chase cards from those years, or is the set itself more important?
Standout seasons are cool but not the primary driver; the overall set quality and the ability to capture a peak moment matter more to me than a single MVP or award year.
The Football Card Podcast #37: Only 3 Football Cards in 54 Six-Figure Sales… What Does That Tell You?
Q: Are unlicensed Prizm products something you would consider, or will you avoid them entirely?
I will not pursue unlicensed Prizm; I think unlicensed will attract risk of chase cards and Kabooms, but I'm not compelled to chase them, and I'll likely avoid the unlicensed route.
The Staging Area #20: Big Sales, Non-Payers, and What It Means for Your Cards
Q: How is non-payment affecting sellers, and what's being done?
Non-payment remains a thorn, but auto-pay adoption and enhanced seller controls are reducing unpaid items; markets are pushing for stronger buyer verification and smarter bidding controls to minimize failures and protect sellers.
