Stacking Slabs

by Brett McGrath

Welcome to the Stacking Slabs, a podcast for sports cards collectors. There's been a tremendous amount of change to our Hobby over the last few years and the one constant has been the passion from the collecting community. Stacking Slabs is built by the collector and lives to tell stories for the collector.

What listeners say

A curated, balanced selection of Apple Podcasts reviews.

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.

Triangle Sandwich · Jul 2025

Amazing content for Sports Cards!! This podcast gets me all excited and fired up for sports cards. I can’t get enough. Super authentic work and genuine passion are involved with this one. A daily listen for me. I listen to this Podcast when I commute to work and back, working out, running errands, and perfect for the plane ride.

If you are interested in cards, and cardboard of all shapes and sizes, this podcast is a must listen. The best interviews and top notch content. There’s something to learn in every episode,

dfreshcards · May 2025

When this podcast is good, it’s great. But when you “shrink your hobby sea,” you put yourself in a box. The friday interviews used to be my favorite part of this show. But it’s become stale. Generic Manning collector #132, generic Manning collector #133, generic Colts collector #56, drakes pc aka the least interesting man in the hobby interview #45, generic manning collector #134, wwe gellman interview #33, generic colts collector #57 and on and on. The host has done a good job selling the whole “shrink the hobby sea” thing. But from a content standpoint, maybe consider expanding your topic sea. If he had more of an open mind and was willing to learn about areas of cards that - gasp - don’t appeal to him personally but appeal to - gasp - other people (imagine wanting to make other people feel welcome), this pod could be so much better. This pod gets a lot of slack because of the longevity and people genuinely liking the host as a person. But this reviewer finds it boring and stale. Cue the “well dont listen, then” response. Good idea ✌️
