In this episode of Passion to Profession—presented by eBay—we sit down with Tim, the founder and Chief Product Officer at COMC. What started as a side hustle built to simplify card buying and selling has grown into one of the largest platforms in the hobby.

Tim shares the original spark that led him to build COMC after leaving Microsoft, what it means to solve real problems for collectors, and how staying close to the cards—both as a developer and a collector—shaped every decision along the way.

We talk about passion, product, and what’s next for COMC as they prepare to roll out innovations two decades in the making.

Plus, Tim opens up about his WNBA collection, including his 2019 Optic Gold Vinyl Sue Bird 1/1 PSA 10 and what drives him to keep building for the hobby he loves.

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

In our season one finale, we’re pulling back the curtain and reflecting on how this show came to life — from a side conversation during Auction Talk to a full-fledged platform for WNBA card collectors.

We talk about:

• The original expectations we had going in (and how they were shattered)
• The feedback that made us realize this show mattered
• Why collector-driven, community-focused content will always win
• What’s still missing in the WNBA card market
• How data backs the growth we’re seeing — and what it means for collectors
• And yes, our favorite part: the cards

Whether you’ve been with us since Episode 1 or you’re tuning in for the first time, this one is about why we collect, why we keep showing up, and why this community is only getting stronger.

We’re not done. Season two is coming. Let’s keep building.

Welcome to the first episode of The Football Card Podcast — a new weekly show hosted by Pack Nicholson (@packnicholson) and powered by Stacking Slabs.

This episode sets the tone for everything to come. We’re talking football cards, collecting strategy, eBay negotiation tactics, player nostalgia, and why certain sets (like 2002 Finest and 2010 Topps Chrome) hit harder than others.

Pack and Brett each break down recent pickups — including an Eddie George memorabilia refractor, a Matt Forte gold, and an Andre Johnson Colts gold vinyl — and discuss what they’re building and why. They cover the psychology behind card buying, the emotional rollercoaster of NFL fandom, and how running backs are quietly carrying the culture.

If you’re into football, football cards, or finding new ways to enjoy the hobby, this one’s for you.

In this episode of Smashing BIN, I’m joined by Alex (@leatherhelmetcards) to talk about his BIN smash of the 2002 Finest Kurt Warner Gold Refractor /25 PSA 10.

This isn’t just a card—it was a turning point. We dig into how this card helped reshape Alex’s entire approach to collecting, the emotional tug of picking between Gold and Xfractor, and how the concept of a “capital pool” helped him make it happen.

We also talk:

• The confusing but rewarding Kurt Warner catalog
• What makes 2002 Finest such a beloved set
• Why Bret Hart is the Raptors of wrestling
• And how navigating gold parallels today feels like getting over a breakup

By the end, you’ll hear how this story came full circle in the best possible way.

Most collectors spend their days refreshing save searches and chasing listings. But some of the best cards? They never hit the market.

In this episode, Brett shares two recent pickups—both landed without a public listing and made possible through one thing: conversation. These deals weren’t about luck. They were the result of trust, timing, and building real relationships in the hobby.

If you're tired of missing out or feeling stuck in your routine, this episode is your reminder that the best deals often come from the quiet places—the DMs, the group chats, and the unexpected texts from fellow collectors.

This one’s about playing the long game and understanding why the best cards in your collection might not come from eBay… but from a conversation you start today.

We’re going Broadway on this one.

In this episode of Card Ladder Confidential, we unpack the psychology behind the rookie card obsession, debate the growing importance of Black Finite across sports, and explore the concept of “turning point” cards—those game changers that shift how you collect forever.

Topics include:

• Why we chase firsts and what makes a card matter
• Rookie catalog analysis and how it can make or break a PC
• The rise of Black Finite across WNBA, basketball, and beyond
• Market reactions to Caitlin Clark’s one-of-ones
• A philosophical breakdown of rarity, significance, and decision-making in collecting

This episode will challenge the way you think about collecting. And you’ll walk away with a better understanding of your own rules—and when to break them.

Ted from TNT Sports Cards has been in the game since 1994 and selling on eBay since 1998. In this episode of Passion to Profession sponsored by eBay, he shares the secret behind his staying power: consistency, service, and a deep-rooted passion that started when he learned to read from the backs of 1980 Topps cards.

We talk about:

• What it was like selling during the junk wax era
• Why eBay became his lane early on
• His evolution from local shows to high-volume sealed wax seller
• What collectors miss when they overlook the importance of operations
• How the rise of Pokémon relates to rising hobby box prices
• Why 1996–1999 was the golden era of innovation in card design

Ted keeps it real about business, customer expectations, and what it takes to build something that lasts. Whether you’re a collector, seller, or trying to figure out your next step in the hobby, this is a conversation worth your time.

This week on The WNBA Card Podcast, we ask the big question: what will it take for another WNBA player—not named Caitlin Clark—to break through to collectors outside the space?

Brett and Katelyn explore the current dynamics shaping the W card market, discuss how narrative and rhetoric shape demand, and spotlight why players like Napheesa Collier and Breanna Stewart deserve more hobby attention.

We get into:

• Why comparing Clark to Curry helps collectors connect
• How Sabrina Ionescu’s market is impacted by expectations
• Why Stewie is the most undervalued winner in the hobby
• What the $274K Black Finite sale tells us about parallel preferences
• The future of college cards and whether they can rival pro releases

We also share our weekly pickups, celebrate a collector on the rise, and round it out with some buzzer beater questions—including Brett’s all-time Notre Dame starting five.

This is the Caitlin Clark episode... but it’s also a reminder that the WNBA has depth, stories, and stars worth your collecting attention.

What would it take for you to leave the country to get a card?

For Jonah (@jd9cards), the answer was three trips to Puerto Rico and years of research for a card most collectors will never see in person: the Josh Gibson from the 1950–51 Toleteros set.

At 25, Jonah isn’t your typical vintage collector. He’s building a collection rooted in history, rarity, and significance—tracking down Negro League legends, studying card photography, and connecting with sellers who want their stories carried forward.

This episode is about more than a transaction. It’s about patience, trust, and collecting with purpose.

You’ll walk away thinking differently about what matters in your collection.

What happens when a card you’ve been circling for months suddenly appears with a price that feels right?

In this episode of Smashing BIN, Joe (@low_pop_papi) returns to break down his acquisition of the 2018 Panini Kaboom! Gold Stephen Curry /10 PSA 10 — a card that changed the trajectory of his entire collection.

We talk about:

• The emotional tension behind a high-dollar BIN smash
• Why Kaboom Golds were heating up in mid-2023
• Comparative analysis across the 2018 multisport checklist
• How a single card can push a collector to go all-in on a player
• Why the Panini era’s non-numbered inserts might be the hobby’s best-kept secret
• And what the $500k+ Curry Topps Now sale signals about the hobby’s time-shifted future

This isn’t just a Curry story. It’s a collector’s blueprint for doing your homework, trusting your instincts, and building a meaningful PC.
