My Card Inventory: Sports Card Collecting and Investing Podcast

This episode starts with one card, a Kevin McGonigle red Bowman I bought as a $100 FanCash bet on Rookie of the Year, and turns into the comp argument popular within the hobby: should shipping be included when we say what a card sold for? My answer is 100% yes. I break down why shipping is part of the real cost on both sides of a sale, why leaving it out distorts cheaper cards the most, and how I track true all-in cost on every card instead of a sticker price. Agree or think I am wrong? Let me know.

I sent 3 cards to DCSports87 for consignment for my first time.

Here's my honest review of the whole experience, start to finish.Overall, it was really smooth, I was happy with the prices, and I ended up with MORE money than if I'd auctioned them from my own account. Way more eyeballs on the cards too.

The 3 cards:

2024 Prizm WNBA Caitlin Clark base (PSA 9)

2024 Prizm WNBA Caitlin Clark Purple Prizm (PSA 8.5)

2024 Bowman Walker Jenkins Chrome Prospect Auto Refractor /499 (SGC 9, 10 auto)

Two things to watch out for if you submit cards for consignment:

Raw (ungraded) cards can go lower than you'd expect — buyers assume cards sent to consignment aren't in great shape.

Always double-check your listings — cards sometimes get mislabeled.

I sold three cards recently, and each one taught me something I wish I'd understood earlier. In this episode I break down all three sales and the exact lessons behind them, so you can sell smarter than I did.

The 3 lessons:
1. Ignore the sunk cost fallacy. What you paid for a card is gone. The only number that matters when you sell is what it's worth right now, not what you need to "break even."
2. Know what you really paid. Your true cost isn't the sticker price. It's the item + shipping + fees + grading, all in. Get that wrong and every profit call after it is wrong too.
3. Timing is everything — know when to get out. Cards are a market. Reading the moment (hype, print run, the player's trajectory) is often the difference between a great sale and holding a bag.

The cards in this episode:
• Walker Jenkins — 2024 Bowman Chrome Prospect Auto, Speckle Refractor /299 (PSA 10)
• Caleb Williams — 2023 Bowman University 1st Auto
• Josh Allen — 2018 Panini Contenders Optic ROY Contenders Auto (BGS 9)

The 5 platforms I actually use to buy and sell cards, and the honest pros and cons of each. I break down Fanatics Collect, Alt, eBay, Arena Club, and COMC: where each one shines, where it falls short, and which I reach for depending on what I'm buying or selling.

Whether you're flipping, investing, or just clearing out a collection, this should help you pick the right platform for the job.

Is MBA grading actually worth it? My honest take: I don't think grading is necessary for the hobby, and as a collector you don't need it. But as a seller, if a grade can push a card's price up, I'm willing to try it and find out.

So I put it to the test and sent four already-graded legends through MBA's crossover service to see how they come back:

• 1956 Topps Jackie Robinson (PSA 2)
• 1955 Topps Sandy Koufax (SGC 1)
• 1965 Cassius Clay / Muhammad Ali (SGC 3)
• 1979-80 O-Pee-Chee Wayne Gretzky rookie (SGC 1.5)

Results aren't back yet, so this is part one: the thesis, the reasoning, and why I picked these four. A follow-up drops when the grades return.

Where do you land? Is grading necessary, or just a price lever?

I spent $800 on a pair of Walker Jenkins 1st Bowman Chrome autos — and it's the purchases I regret most in 2026. In this video I break down exactly why it was a mistake: I don't normally buy prospects, Jenkins isn't a player I'm passionate about, and I let a wave of YouTube hype push me into it. The kicker? The cards have actually come DOWN since I bought them — even after he got called up to the majors.If you're tempted to chase the next big prospect or deviate from your traditional collecting strategy, learn from my $800 lesson before you pull the trigger.The cards:• 2024 Bowman Chrome Prospect Auto Refractor /499 — SGC 9 (Auto 10)• 2024 Bowman Chrome Prospect Auto Speckle Refractor /299 — PSA 10What I get into:• Why prospecting doesn't fit how I actually collect• Buying a player I'm not passionate about (and why that matters)• How much the YouTube hype cycle drove my decision• Why a call-up didn't save the value• What I'd do differently — and what I'm buying insteadBe honest in the comments: what's the one card purchase YOU regret the most? 👇If this saved you from a bad buy, hit like and subscribe for more real talk on the hobby — the wins and the losses.#SportsCards #WalkerJenkins #Bowman #TheHobby #BaseballCards #Prospecting #CardCollecting #MinnesotaTwins

I sold my Tom Brady, LeBron James and Stephen Curry rookie cards, and looking at prices now, I apparently sold way too early. In this episode I break down what cards I let go of, what those cards are selling for now, and overall thoughts on how the market is running hot with almost every card going up (and what I'm doing now).This isn't a "never sell" podcast. It's about being honest that a rising market makes every sale look smart in the moment, and how to think it through before you let a card go.Cards in this video:- 2009-10 Topps #321 Stephen Curry (BGS 8.5)- 2003 Topps Chrome #111 LeBron James (PSA 8)- 2000 Bowman #236 Tom Brady (BGS 8.5)I track every card, what I paid all-in, and what I actually cleared on each sale with My Card Inventory, the tool I'm building for collectors.

After building 10K Card Journey through blog posts, podcasts, videos, and many hours in the sports card hobby, I’ve decided to officially move on from the project.

In this final episode, I talk about why I’m shutting down 10K Card Journey, what I learned from the experience, and why I’ve decided to focus fully on a new niche I believe has long-term potential: tennis cards.

I’ll also introduce my new project, Tennis Card Collective — a platform dedicated to tennis card collecting, education, and building one of the largest selections of tennis card singles available online.

Whether you’ve followed 10K Card Journey from the beginning or just recently discovered the content, I truly appreciate all of the support along the way.

In this episode, I take you inside my personal sports card collection and highlight some of my favorite cards — the ones that mean the most to me as a collector and investor.

I share why I bought them, what makes them special, and how they fit into my long-term strategy for 10KCardJourney.

This is my first time experimenting with a video format, so let me know if you’d like to see more collection showcases in the future.

In this episode, I explore how broader economic trends can influence the sports card market — even if nothing about the cards themselves has changed.

Sports cards may feel like their own world, but they’re still part of a larger economy. When consumer spending tightens or financial conditions change, it can affect how collectors buy, sell, and value cards.

This episode isn’t about predicting a crash or telling anyone what to do — it’s simply about encouraging collectors to think about the bigger picture and how macroeconomic factors could influence the hobby.

As always, this is just my personal perspective as I document my own journey building a sports card portfolio with a $10K starting budget.
