Negotiation and How to Get Leverage in Sports Cards

Slabnomics ·

2026/04/07

Most card collectors think negotiation is just haggling: subtract from the sticker price, meet in the middle, done. It's not. In this episode, Matt breaks down the actual framework behind why deals happen and why they don't using Chris Voss's tactical empathy principles applied directly to the card market. You'll hear both sides of a real card show weekend: a buy that closed at his number and eight cards that didn't sell and why both outcomes were exactly right. Levera...

Diving into Liquidity: 3 Types and How To Exit the Pool

Slabnomics ·

2026/03/31

This episode applies institutional liquidity frameworks to the card market. Three types of liquidity and what each one means for your portfolio. Why soccer trades like a two-buyer auction room despite 91% index gains. How price slippage destroys your comp stack when you hold multiples and list them sequentially. The difference between a market that is moving and a market that is coasting on inertia. And the exit framework that captures the middle of a move without the ego of trying to sell th...

Financial Inertia: What Breaks the Card Market

Slabnomics ·

2026/03/24

Have you ever been right about a card and watched the market ignore you for months? This episode breaks down the hidden architecture driving card prices. Not the surface-level "supply and demand" explanation, but the actual forces underneath: the psychological biases that keep incorrect prices in place far longer than they should, the structural mechanics that used to prop up modern sets but largely don't anymore, and the specific signals that tell you when inertia is about to break (in...

Becoming the Card Show Oracle

Slabnomics ·

2026/03/17

Most people walk into a card show with a feeling. A vague sense of what looks good, what seems reasonably priced, what a dealer's enthusiasm is worth. This episode is about the gap between walking a show with a framework and walking one with a feeling, and what that gap costs you over time. From there, the episode gets concrete. Nobel Prize-winning economist George Akerlof's "Market for Lemons" explains why card shows can be structurally inefficient. Matt walks through a rea...

Return of the King: Topps Chrome

Slabnomics ·

2026/03/10

Topps Chrome Basketball is back, Fanatics owns the licenses to all three major American sports leagues, and the hobby is generating real noise. But this isn't a hype story. It's a supply structure event, and those play out differently than people expect. In this episode, we walk through the history of Topps Chrome refractors, the gem market cap data behind the LeBron James 2003 rookie, how Panini multiplied parallels from 11 to 80+ variations and what that did to base card values, and what it...

I Found The Most Undervalued Cards in the Hobby

2026/02/24

Grading has a structural mispricing that represents one of the most compelling arbitrage opportunities in the sports card market. This episode breaks down the population data, valuation multiples, and market mechanics that explain why. Key Analysis: *PSA 10 to BGS 10 Pristine population analysis using 1989 Upper Deck Ken Griffey Jr as case study *Why the 39x rarity differential only translates to 1.79x price premium (and why this is broken) *How the junk parallel era created supply fatigue ...

Meta-tagging 311 Sales: Lessons My Sports Card...

Slabnomics ·

2026/02/17

I analyzed every trade I made over 10 months in one of my buckets: 311 sales, $55,000 deployed and fed it all into Claude AI to find patterns. The result was a complete rebuild of how I think about sports card portfolio construction. Using meta-tags to track performance across player tier, set quality, rarity, and card type, I discovered that sets really do matter, and GOATs matter most in soccer. The finance brain wanted diversification across mid-cap players and inte...

Prizm Comparison Across Sports

Slabnomics ·

2026/02/10

In this episode of Slabnomics, I pulled every single Panini Prizm base and silver parallel for both players: Lebron James and Lionel Messi. I compared PSA 10 populations, last sale prices, and a metric I'm calling Gem Market Cap. What I found shook me. This episode covers: How supply, demand & price discovery work differently in cards vs traditional markets The MLD Valuation Framework (Market, Legacy, Design) What "Lowest Common Denominator" analysis means for cross-player comparison ...

Which archetypes have the most seasonal volatility? How do sports card markets mature as alternate assets? From GOAT multipliers to post-hype sleepers, generational prospects to position-specific volatility bands—the frameworks being built behind the scenes at Slabnomics.

Want to hear it how it is in the Hobby and tired of everything either being positive or else the sky is falling? This episode is for you. This week we break from the soccer content to bring on Mike Gioseffi from Sports Card Nonsense. Mike doesn't hold back: "I've heard soccer will be the next big thing since I was on the Orange team in second grade. Still waiting." We debate whether soccer cards will ever catch baseball and football in the US market, why baseball still commands 30% of t...

PSA 9 is Dead. All Hail Gem Mint 10

Slabnomics ·

2026/01/13

Is the PSA 9 dead? I dove into the data across three eras (vintage, modern, ultra-modern) and four sports (baseball, basketball, football, soccer) to find out when PSA 9s hold value, and when they're just an expensive failure certificate. The numbers are staggering: PSA created 31 million new 10s since 2020, compared to just 5 million total from 1991-2019. In 2025 alone, 6.5 million new PSA 10s entered the market. When gem rates hit 60-70%, the 9 becomes meaningless. In this episode: Why v...

State of the Hobby 2025 Everyone keeps saying this is 2021 again. They're wrong. And if you're positioning like it's 2021, you're going to get hurt. I spent weeks treating the card market like an equity analyst treats a stock: pulling index data, PSA submission numbers from SEC filings, volume metrics by price tier. What I found changed how I'm positioning for 2026. In this episode: THE CORE INSIGHT, THE PSA PROOF, THE DEMAND SHIFT, CATEGORY BREAKDOWN (by sport+Pokemon), THE BILLI...

2025/12/16

PSA has officially acquired Beckett, and this is more than breaking news. It’s a structural shift in the sports card market. In this episode of Slabnomics, we break down what the PSA–Beckett acquisition actually means for collectors, investors, and flippers. We zoom out to examine where we are in the market cycle, explain why this moment signals consolidation, and then zoom all the way in to the microeconomics of cards and sets...the containers that ultimately determine long-term value.

1 Year of Selling Sports Cards: Grading (Final Part)

Slabnomics ·

2025/11/25

We wrap the mini-series with grading—the alchemy of the hobby when used correctly. I share the actual ledger: 1,127+ cards graded, $20K+ in fees/shipping, PSA (525 cards; ~$11.7K) and SGC (602 cards; ~$9.5K), and why I’d only re-submit ~21% (PSA) and ~17% (SGC) today. You’ll get a pre-grading checklist, a tier/upcharge strategy that protects cash flow, and post-mortems on failed CGC→PSA and BGS→PSA arbitrage. You’ll learn When a card shouldn’t be graded PSA vs SGC vs BGS vs CGC—where eac...

Following Part 1 (buying), this episode breaks down the sell-side of my first year—$98K on eBay—and the exact lessons that moved the needle: how to seed early feedback, how to structure PWE vs. bubble mailer shipping (and when to use non-machinable stamps), the true cost of fees & promoted listings, and a negotiation framework so you stop caving under pressure. We also cover budgets to avoid forced sales, when wax/singles make sense (rarely), and why multi-market selling unlocks faster ex...
