Stacking Slabs

On this episode of Passion to Profession, Brett sits down with Bryan Thiessenhusen, CEO of Black Gold 
Sports Cards.

Bryan didn’t start with an advantage. He started with tubs of cards, a full-time accounting job, and a willingness to take risk.

What followed was a fast build.

He turned grading prep into revenue.
Turned live streaming into scale.
Turned a side hustle into a 30+ person operation.

In this conversation, Bryan breaks down:
 How he used his accounting background to build systems and track every dollar 
 Why being early and doing what others avoid created momentum 
 The role of content in driving growth and attention 
 What most people get wrong about risk, work ethic, and scaling in the hobby 
 How culture and trust became the foundation of Black Gold 
This is a conversation about building something real.

If you’re collecting, operating, or thinking about turning your passion into a business, this one will make you think.

With Ryan out this week, Adam Gellman is joined by Jamison Long of Port City Sports Collectibles to talk wrestling cards from a different angle.

Jamison has built one of the fastest growing card shops in the country. He also collects at a high level. That combination creates a different lens on the hobby.

They cover:
• What changes when you go from collector to shop owner
• Why most collectors misunderstand wax pricing
• The importance of community inside a card shop
• WWE Chrome debut patches and why they matter
• Big recent sales and what they signal about the market

The conversation also hits WWE storylines, prospecting, and how new stars like Oba Femi are impacting collector behavior.
This episode is a reminder that the hobby is not only about big cards. It is about how you show up, what you chase, and how long you can stay in it.

Pack and Brett open Episode 40 with a real-time hobby mystery.

A stolen 2025 Prizm Gold Lance Briggs resurfaces across state lines. The hunt is on. Questions start stacking. How many cards disappear before they ever hit public data?

From there, the conversation shifts to what collectors are feeling right now.

The pressure.
The speed.
The constant sense of missing out.
They break down why the hobby feels like a sprint even when everyone says it’s a marathon.

The episode also covers:
• The gap between data and decision-making
• Why social media is distorting collector behavior
• When to sell and how to think about consolidation
• Big recent sales including a $31K Gronk Prizm Gold and a $90K Brady 

They close with a reminder most collectors need to hear:
You don’t need every card.
You need the right ones.

Collectors think in comps.
Operators think in systems.

That gap is where mistakes happen.

In this episode, I break down what I learned from 12 hobby operators and how it applies to your decisions as a collector.

We cover:
• Why trust is the product
• Why reacting leads to regret
• How operators actually view comps
• The role of systems and communication
The hobby is growing.
But the rules are not evenly distributed.

If you understand how operators think, you put yourself in a better position to win and avoid mistakes.

Ask yourself one question.
Do the people you buy from reduce uncertainty or create it?
