    Why You See "Buying, 80%" (And What to Do About It)

    Every Facebook card group has the post. Cash in hand. Buying at 80% of comp. Same wording, different accounts, every week. Nobody asks where the 80% came from. Today we do. This episode walks through the why of that number, the three cognitive biases that keep sellers accepting, and two practical things to do so we can stop seeing those posts. Why this practice preys on the very people we should safeguard for the long term good of The Hobby: New Entrants. Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    The Discoverable Market: Why Cards Aren't Like Stocks

    Both sides studied the stock market. Nobody applied this to cards. Until now. In this episode of Slabnomics, we introduce the Discoverable Market framework and make the case that the card market is neither efficient nor random. It's exploitable. The information exists. Most people just aren't using it. ✅ What the Efficient Market Hypothesis actually means ✅ The 3 conditions required for market efficiency ✅ Why collector behavioral errors aren't random The card market is newly becoming a real market. The frameworks that explain its behavior are barely being applied. The information required to price these assets correctly is freely available — and widely ignored. That's the definition of a discoverable market. The question is whether you want to do the work. Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    Negotiation and How to Get Leverage in Sports Cards

    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.  Leverage is the only variable that matters. Your job is to understand whether you have it.  Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

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

    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 the peak. Topics: Sports card liquidity explained • Price slippage and comp arbitrage • Why thin markets move violently • Spotting trend exhaustion • Scale out exit strategy • Time stop discipline • World Cup sell window mechanics • Card Ladder price accuracy Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    Financial Inertia: What Breaks the Card Market

    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 either direction). The episode closes on the macro demand picture — where the center of gravity in this hobby is actually shifting, why the high-end and low-end are now operating by completely different rules, and what the generational handoff means for which cards have durable long-term appeal versus which ones are consumer products wearing an investment thesis.

    Becoming the Card Show Oracle

    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 real decision from the Dallas card show, a 2009 Topps Chrome Jeter gold /50 in an SGC 10, and exactly which factors made it worth a serious look while the Jordan Fleer rookie two tables over didn't. Topics Covered: Why choice overload degrades decision quality — and how most retail investors fall into the same trapThe Fama-French three-factor model and what a card market equivalent actually looks likeGem rate, set tier, population trend, and price-to-comp as measurable card factorsGeorge Akerlof's Market for Lemons and why information asymmetry is the real game being played at every card showSlabnomics as a filter, not a prediction machine: how to walk into any room with a bias-resistant, repeatable process Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    Return of the King: Topps Chrome

    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 actually means that the Panini Prism era is now a permanently closed chapter. We also look at the retail math on modern wax boxes, the football refractor population counts that will surprise you, and what all of this means for collectors already positioned in Prism cards of legitimate stars. The supply structure just shifted. Here's how to read it. Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram
