Topps Chrome Football Has No Competition and What This Means
#929
Last Tuesday at 6:00 AM

Topps Chrome Football is back.

But this time it stands alone.

No competing brand. No second option. No alternative lane.

That changes how you collect.


In this episode, I’m not breaking down the checklist or the hits. You can find that anywhere.


I’m focused on what this moment reveals about you as a collector.


For years, your decisions were shaped by comparison.


The question shifts from what do you like more to do you participate at all.


T...


Passion to Profession: From Card Breaker to CEO with Ryan Johnson (@cardcollector2)
#927
Last Monday at 6:00 AM

Ryan Johnson didn’t set out to build a 35-person company.


He wanted to open cards.
Share what he was buying.
Be the resource he never had.

Then the business grew.


In this conversation, Ryan walks through the shift from collector and content creator to operator responsible for people, systems, and outcomes.


We talk about:

 The moment decisions started impacting other people  Letting go of control and building a real team  Why communication breaks when you scale  How cash becomes a tool for speed and growth  T...


The WNBA Card Podcast: The Weight of Expectations and How Paige Met the Moment with Ryan (@reservoirsportscards)
#928
Last Sunday at 6:00 AM

Katelyn sits down with Ryan (@reservoirsportscards), a UConn collector who went all in on Paige Bueckers before the market caught up.

This is a conversation about conviction.


Ryan didn’t start as a collector. He started flipping cards. Watching markets. Chasing value.


Then Paige changed everything.


What started as an idea turned into a strategy.
Then a PC.
Then an obsession.


We get into:

 The moment Paige became “the one”  Turning a $19K purchase into a record-breaking sale  Why Bowman Chrome changed WNBA collec...

Adam and Ryan break down everything happening right now.

Last Friday at 6:00 AM

Topps Chrome Football returns and the hobby is already moving fast.

• The tension between chasing new vs staying focused on your lane


Shrink the Sea: Why Niching Down Builds Stronger Collectors
#924
04/09/2026

The hobby isn’t one market. It’s many.

But we still act like everything should live under one roof.


In this episode, I push on a simple idea. The hobby gets stronger when we get more focused. Not bigger. Narrower.

When everything sits in one place, collectors get lost. They default to the loudest voices and the most visible cards. 

Depth disappears.


When you shrink the sea, something changes.


Collectors find their lane.
They find people who collect like them.
They build...


Patience is the Difference Maker: How to Collect When Everything Tells You to Buy Now
#923
04/08/2026

There is more money, more cards, and more noise in the hobby than ever before.
Over $605M in monthly sales. 


Every platform is built to keep you moving.
Scrolling. Watching. Bidding. Buying.

So where does patience fit?


In this episode, I slow things down and challenge a hard question.

Can patience survive in a system designed to push you to act fast?


I break down the forces working against you.
Why urgency feels real.
Why auctions pull you in.
Why losing a...

#922
04/07/2026

Brett and Tory break down a record-setting moment in the hobby.


Card Ladder reports $605M in monthly sales.
dcsports87 hits its biggest month ever.
And a Shohei Ohtani All Aces PSA 10 sells for over $15K.


This conversation goes deeper than headlines.


You’ll hear what happens when content drives brand growth.
Why niche categories like wrestling and TCG are heating up.
How scarcity, demand, and perception collide in today’s market.
And what Ohtani is doing to rewrite the rules collectors have followed for years.

#921
04/06/2026

What happens when a single moment turns into a career?


Ethan from Tombstone Collectibles joins Passion to Profession to break down how one pull opened the door… and what it actually takes to build a modern hobby business at scale.


This is not a conversation about ripping packs.

This is about building infrastructure, managing talent, and operating in a market that moves fast.

We get into:

 Why most breakers fail before they ever get started  The importance of relationships in live selling  How Tombstone scaled from one stream to a mu...


Booked to Last #13: Chrome Is Coming… So What Are You Doing With Your Money?
#920
04/04/2026

Adam and Ryan are back and the timing couldn’t be bigger.


With Topps Chrome around the corner, the wrestling card calendar is about to hit hard. Exalted is here. Chrome is next. Then more follows.


The question isn’t what’s coming.
It’s how you’re going to handle it.


In this episode, they break down:

 Why Exalted feels mistimed in the current release cycle  The overwhelming momentum building behind Chrome  What collectors are missing when they look at wrestling market data  How private deals are shaping the hobby...


The Football Card Podcast #41: Patience, Pricing, and the Problem with How We Move Cards
#919
04/03/2026

You feel it every time you log in.


Everything is moving fast.
Listings. Prices. Decisions.


The hobby wants you to act now.

In this episode, Brett and Pack slow it down and ask a harder question:


Can you stay patient when everything around you pushes speed?


They get into:

How collectors lose control when money moves too fastWhy auctions feel better than direct dealsThe hidden cost of selling your own cardsShipping mistakes that create risk for everyoneWhat “fair value” really looks like in toda...


Building in Public: How to Scale a Dealer Business Online and In-Person with Max (@Cardsmax)
#918
04/02/2026

What does it look like to go all in on cards and make it work?

In this conversation, Brett sits down with Max (@Cardsmax), a full-time dealer who has built his business in the open. He shares how he went from ripping packs as a kid to running a national buying and selling operation driven by shows, eBay, and content.

Discovery Gets Real When You Find the People
#917
04/01/2026

Discovery doesn’t end when you find the card.

That’s where most collectors stop. That’s where most collectors miss.

In this flagship episode, I take the next step from last week and break down what really drives better collecting. It’s not being early. It’s not guessing right.

It’s finding the people who already know what you’re chasing.

I share a message that stopped me in my tracks and forced me to rethink discovery. Then we get into how community shapes your edge.


You’ll hear:<...


Card Ladder Confidential #18: Why Patience Wins in a Market That Won't Slow Down
#916
03/31/2026

The market is running. Prices are climbing. Headlines are everywhere.

And yet… the smartest collectors aren’t chasing.

In this episode of Card Ladder Confidential, I sit down with Card Ladder team members Chris McGill and Josh Johnson to break down what’s really happening right now.


We start with the data.
February recorded $481M in online card sales. An all-time high. 


But numbers don’t tell the full story.


We get into:

 Why rising prices without clear reasoning should make you pause  How new collecto...


Passion to Profession: How Black Gold Sports Cards Doubled Their Team in a Year
#914
03/30/2026

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 trac...

The Football Card Podcast #40: The Briggs Bandit, $31K Gronk, and Why You’ll Always Miss Cards
#912
03/27/2026

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...


What 12 Hobby Operators Know That Collectors Can Miss
#911
03/26/2026

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...


Discovery Is the Edge Most Collectors Ignore
#910
03/25/2026

When was the last time you found a card before the hobby told you it mattered?


Not after the sale.
Not after the post.
Not after everyone started chasing it.


Before.


This episode is about discovery and why it is one of the most powerful advantages you can build as a collector.


We are living in a headline-driven hobby.
Attention dictates demand.
Most collectors are choosing from the same small list of cards.


That creates competition.
It creates pressure.<...


The Staging Area #21: WBC Hype, Opening Day, and The WhatNot of It All
#909
03/24/2026

Opening Day is here.

Energy is high. Attention is shifting. And the hobby is reacting in real time.

Tory and I dig into what just happened with the World Baseball Classic and what it actually means for you as a collector. Not the surface-level hype. The real takeaway.

We talk about:

Why moments like WBC create short windows of opportunityWhat happens when demand spikes and how to act on itA Kobe Atomic sale that says more about the market than you thinkWhy Topps Dynasty prices aren’t as crazy as they lookThe ps...


Passion to Profession: Husband and Wife. One Business. Fifteen Hires in a Year with Michael and Mikaela from Rated Rips
#908
03/23/2026

What happens when you walk away from stability to bet on cards?

Michael and Mikaela did it.


Both were CPAs. Both were on a clear path. Then COVID hit. Breaking started. Demand showed up fast. And within months, everything changed.

They built Rated Rips from late-night breaks into a full-scale consignment business.

They hired 15 people in a year.

They shifted from taking money out of the hobby to putting money back into collectors’ hands.

In this conversation, we get into what it really looks like to bu...


The WNBA Card Podcast: Panini and Sabrina — The Rise of New Forces with Kyle (@kyle_collects)
#907
03/22/2026

This episode is about a moment that changed everything.

Katelyn sits down with Kyle (@kyle_collects) to break down the shift from 2019 Donruss to 2020 Prizm and why that stretch still shapes how collectors approach WNBA cards today.

They talk through what it felt like to discover WNBA cards before the spotlight. Ripping boxes no one wanted. Finding cards that never made it to showcases. Learning the players one card at a time.

Then everything changed.

Prizm arrived. Sabrina entered the hobby. The world shut down. People started paying attention.

Booked to Last #11: From Blaster Boxes to Building a Collection of 1/1s with Steve (@s.a.m_wwe)
#906
03/21/2026

Adam and Ryan sit down with Steve(@s.a.m_wwe) , one of the most focused Rhea Ripley collectors in the hobby.

The conversation starts with a simple moment. A blaster box in 2022. That moment turns into chasing rainbows, building sets, and eventually acquiring 1/1 cards.


This episode is about how that happens.

Steve shares how he built his collection from scratch. Why he chose Rhea Ripley. And how relationships helped him land cards most collectors never even see.


They also break down what’s happening right now in wrestling ca...

#905
03/20/2026

Pack and Brett  open the episode by unpacking the reaction to a viral take about football collectors and why people struggle when opinions get stated in absolutes.


They explore a bigger question beneath the noise.
Who is actually collecting versus who is investing?


The conversation moves into how money enters the hobby.
Million dollar sales.
Investor behavior.
And why volume of collectors matters more than headline prices.

From there, they dig into:

Why scarcity does not always mean more valueThe difference between meaning and rarity in c...


Discovery Is the Edge in Collecting with Max (@putnamcards)
#904
03/19/2026

Most collectors spend their time watching big sales. Few spend time learning how to find great cards.


That gap matters.

In this conversation with Max (@putnamcards), creator of Hoops Collectors, we talk about what actually creates an edge in the hobby.


Not headlines.
Not hype.
Not million dollar cards.


We get into:

Why most content focuses on cards no one can affordHow research leads to better collecting decisionsWhy overlooked sets and inserts hold real opportunityThe role nostalgia plays in what you chaseWhat happens when you...


When the Card Never Shows Up: A Lesson Every Collector Needs
#903
03/18/2026

In this flagship episode of Stacking Slabs, Brett shares a tough experience that every collector fears. A highly anticipated card arrives… but the package is empty.

This conversation goes beyond one missing card. It’s about trust, responsibility, and how collectors can protect what...

Over the past 18 months, Brett has spent time talking with owners, builders, and operators across the sports card industry.

More than 60 conversations.


Shop owners.

The hobby is growing fast. Online card sales tracked by Card Ladder reached $481M in a single month.


Companies are expanding.
Infrastructure is growing.
New businesses are launching.


But the knowledge required to build a business in this space remains scattered.

What does it mean to collect a franchise player?

$481 M in One Month: The Trust System Behind the Hobby’s Biggest Sales Month
#897
03/12/2026

Card Ladder tracked $481 million in online card sales in one month.


Most collectors see the cards.

This episode looks at the system behind the number.


Brett reverse engineers the $481M month by examining the infrastructure that allows collectors to transact at scale. Marketplaces, pricing data, grading, and vaults all play a role in building the trust required for buyers and sellers to complete transactions online.


Collectors chase cards.

Operators build the rails.

Both rely on trust.


This episode explores the infrastructure...


Second Chances in Collecting: When a Miss Turns Into a Win
#896
03/11/2026

Every collector has a card that got away.


In this episode, Brett shares the story of a card that came back around. Earlier this year he lost the 2020 Crown Royale Crystal Platinum Tyrese Haliburton 1/1 at auction after spending hours researching it and building conviction around the card.

The WNBA Card Podcast: On Nostalgia with Katelyn (@coldlunchcards)
#894
03/08/2026

Season 4 reaches its midpoint with a solo episode from Katelyn (@coldlunchcards). 

The topic is nostalgia and how it shapes the way collectors approach WNBA cards.


Many collectors chase rookie cards. That is a bet on the future.

Many collectors chase early legends. That is a connection to the past.


But the WNBA sits in a different position than most leagues. The league began in 1997. Many collectors building WNBA collections today did not grow up watching those early seasons.


So what creates nostalgia when the memory is n...

#890

What happens to your collection when your player goes down?

In this Collector Conversation, I sit down with Rodney (@enjoycards_ig) to talk about what it’s really like to collect Tyrese Haliburton during a lost season. We revisit the Game 7 injury. The shock. The numbness. The reality of a gap year.


Then we dig into the cards.

Does an injury change your conviction?
Do you slow down or lean in?
Are lower prices an opportunity or a warning sign?
