Thinking about grading cards? Start here. After 1,500+ submissions across PSA, Beckett, SGC, and CGC, I break down what each grader actually costs, how long it really takes, where each one wins, where each one fails, and the part almost nobody covers: how each grader turns subgrades into the number on your label. Inside:  → Prepping and shipping submissions the right way  → PSA, Beckett, CGC: pric...

1996 Topps Chrome Football is the inaugural set of the most important modern chrome brand, and the market still has not priced it correctly. In the first Slabnomics set deep dive, we go through the full history: why Topps needed an innovation after junk wax fatigue, how 1993 Topps Finest set up the refractor, and why Topps was so unsure about Chrome that they barely printed it.  Then the math.  We...

Two data-backed frameworks for buying cards in 2026. First: the psychological barrier learned from 800+ cards. Only one pattern held with strong correlation. Anchoring, cascading demand, and pop-vs-price gaps explain why.  Second: the generational window. Pokémon proves demand is predictable. Map and trust. Applied to Ohtani, Lamine Yamal, and sports cards broadly. Data over hype. Use the hype, do...

The sports card market is up big. Disney is up 5x in six months. Pokemon volume is at all time highs. So the question everyone is asking: how much longer? Let's talk dry powder.  The rotation from modern into vintage.  The speculative tells in sealed wax, breaks, and repackers.  And the biggest structural throttle on the hobby right now: PSA and Beckett cutting their lower grading tiers, whic...

 9 grading mistakes killing your sports card and Pokémon profits broken down by skill level.  Matt covers PSA's new 50–70 business day turnaround at the $80 tier, why Beckett only bumps a certain amount off the average, how PSA actually grades, and why annualized ROI matters more than raw margin.  Beginner, Intermediate, and Advanced grading traps drawn from ~$50K in personal grading spend ov...

Five of the most graded cards in history. Every grade from every grader. The data says a PSA 10 is easier to obtain than most competing top grades, and the market pays for it anyway. Cards analyzed: 2023 Van Gogh Pikachu, 1989 Upper Deck Ken Griffey Jr. rookie, 1990 Fleer Michael Jordan, 1986 Topps Jerry Rice rookie, 1999 Unlimited Charizard Holo. Covered: PSA vs BGS vs CGC vs SGC vs TAG, gem rate...

Grading built this market. Grading is now changing again. This episode traces card grading from the 1990s, when buyers and sellers eyeballed condition and negotiated it live, through the trust-building years of the mid 2010s, into the COVID volume surge that turned grading into the backbone of an asset class. We cover what old label standards mean for the population data you rely on today, and why...

The bull run is roughly a year and a half old. People are getting nervous. Matt takes the temperature three ways: Fanatics Fest, the National, and the SoCo Expo. Three different reads on the same hobby. Covered in this episode:  Loss aversion and the psychology behind selling  Why the COVID comparison breaks down  Institutional money, breaking, and new distribution  The Panini to Fanatics shift as...

The hobby is loud. Buzz, hype, panic...and it all sounds the same until you learn which frequencies matter. Fresh off Fanatics Fest and headed to The National in Chicago, Matt breaks down what he saw on the floor and what it says about where the sports card and tcg markets are going.  Then it's into listener questions: does soccer rebound? Matt walks through: The full World Cup cycle, why he...

What do 18 years of fantasy football tell us about sports cards markets? This episode maps the five phases of dynasty fantasy football onto sports card and TCG investing.  The core argument: most people think you win in the accumulation phase. You don't. You win in the two phases before it, and the two after. Covered in this episode: The running back age cliff as a model for card value curves...

Is the PSA 9 dead? Not so fast. Matt digs into three iconic cards across three sports to test a strange pattern: PSA 9s outperforming PSA 10s. He indexes every sale against player and sport baskets, then walks the data. 2003 Topps Chrome LeBron. 2014 World Cup Prizm Messi. 1999 Base Set Charizard.

 A 15-month soccer card investment fund, reviewed in real time during the 2026 World Cup. Why demand trickles top-down in illiquid markets, why case hits (Kaboom, Color Blast, Stained Glass) hold a floor, and why Messi, Mbappé, and Haaland moved the market while prospects burned capital.

 I looked at all 83 parallels of Victor Wembanyama's 2023 Prizm rookie and indexed every sale against his player market. The best returns did not come from the 1/1s. This episode is a thought dump on that, plus two bigger questions: is vintage cheap relative to modern, and what happens to slab prices now that PSA cut off low-value grading. Your job this week is to tell me which project matter...

One Victor Wembanyama rookie card. Sixty-three parallels. Every grade, every grader, tracked from first sale to today.  Only on Slabnomics will you hear a ranking of all parallels by return percentage AND grader breakdowns. I broke down the entire 2023 Panini Prizm #136 rainbow to find which colors and which grades actually paid, and the answers cut against what the hobby repeats. The famous Silve...

 Out of the 10 biggest names in 1952 Topps, only four beat the S&P 500 over 22 years.  We pulled 9,720 real sales back to 2004, ran every PSA grade through three market cycles, and spoiler alert, the winner isn't the 1952 Mantle. Plus the first look at RRR, the risk-return ratio built to tell you which cards let you sleep at night. Full grade-by-grade breakdown at slabnomics.com.  Keep Bu...

PSA just halted all four of its value grading tiers. The hobby is calling it a failure. We're calling it something else. PSA just acted like a central bank. This episode breaks down why PSA controlling the supply of grades is the same lever the Federal Reserve pulls when it controls the supply of money.  We map the full analogy, the dual mandate between volume and grade integrity, and where i...

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 s...

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 fo...

 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...

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 inerti...
