  • 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.

The Football Card Podcast #51: When Collectors Stop Waiting for Perfect Copies
Q: LSU Tiger Collector asks to distinguish collectors from hoarders, in terms of intention and focus.
They define collectors as curators with a focused strategy and end goal, while hoarders accumulate with minimal design and often without regard to condition or organization.
The Football Card Podcast #51: When Collectors Stop Waiting for Perfect Copies
Q: TL;DR on low print run vintage cards and grading: when does the absence of a slab stop being a factor in valuation?
They acknowledge grading and condition matter, but for ultra-rare, low print run cards, the card's existence and rarity can outweigh grade concerns; in practice, they still prefer decent copies that present well and upgrade only if opportunity arises.
The Football Card Podcast #51: When Collectors Stop Waiting for Perfect Copies
Q: Charm City Tim asks if Andre Johnson would still be in the top five with Calvin Johnson if Calvin had a different quarterback like Matthew Stafford.
They argue that Andre would likely produce more with Stafford, potentially pushing both Johnson and Johnson into higher tiers, but Calvin Johnson's unique physical dominance keeps him in a top tier regardless.
Passion to Profession: Why Bryan (@thzsportscards) Bet on Wrestling Cards
Q: What prompted you to move from NBA cards to wrestling cards?
Burnout from the NBA market and a rekindled passion for wrestling inspired the move; the WWE space offered nostalgia, accessibility, and a growing base of dedicated collectors.
The WNBA Card Podcast: Connecticut Sun Team Collecting, Family Memories, and the End of an Era with Steve (showley2003)
Q: Which players define your Sun collection?
Steve cites DeWanna Bonner, Brianna Jones, DeGeneres Carrington, and Alyssa Thomas as central to his collection, with Thomas the most consistently impactful star and a key focus in his PC.
