  • 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.

Passion to Profession: Selling Cards Without Pressuring Collectors with Collins Boyce
Q: How did you decide to focus on live selling as a channel, and what was that onboarding experience like with eBay Live?
We initially tested live selling with a smaller presence, then paused for a while before applying to eBay Live. After waitlisting and an in-person onboarding meeting in Philly, we launched in February and scaled quickly as we found an engine for consistent streams and larger averages per sale.
Booked to Last: John Cena’s $329,400 Card, the Rhea Ripley Sale, and Tim Bonito’s WWE Collection
Q: What should new collectors understand about product releases and prices?
Initial hype after pre-orders often spikes; prices then stabilize or rise later as supply tightens and breakers push demand, making patience and strategic holds important.
Booked to Last: John Cena’s $329,400 Card, the Rhea Ripley Sale, and Tim Bonito’s WWE Collection
Q: Why is the Rhea Ripley card significant beyond the price?
It's a first-of-its-kind relic with potential to become an enduring all-time card in wrestling, signaling long-term value for future rookies and collectors alike.
Booked to Last: John Cena’s $329,400 Card, the Rhea Ripley Sale, and Tim Bonito’s WWE Collection
Q: What was your first reaction to Cena's $329,400 sale?
Shock at the price and recognition of a turning point for ultra-rare, on-card relics; it underscored renewed enthusiasm and willingness to chase top-tier Cena items.
The WNBA Card Podcast: Building a Portland Fire Collection From the Beginning with Chad
Q: What does being a newer fan of the WNBA mean to you personally?
It represents community, belonging, and the excitement of discovering a sport in a welcoming, fan-centered atmosphere where the community's energy reinforces Chad's collecting choices and personal narrative.
