Over the last few episodes, I walked through my first full year of selling sports cards...my wins, my mistakes, and what I learned in buying, selling, and grading. Today is different.

In this episode I cover: Market cycles & engineered scarcityWhy we’re living in an era of engineered scarcityHow Kabooms became the “reserve currency of...

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...

We also cover budgets to avoid forced sales, when wax/singles make sense (rarely), and why multi-market selling unlocks faster ex...

Send us a text In this opener to my “Year 1” mini-series, I break down everything I learned on the buy-side of the sports-card game—what worked, what wasted money, and how to buy with exits in mind. From the Spain/Messi spark to my first PSA submission (and why it lost), we cover pre-grading, avoiding “rarity for rarity’s sake,” the meaning of liquidity, negotiating bulk discounts, timing buys around seasonal cycles, and using hype as a catalyst—not a crutch. You’ll learn Why pre-grading and ...

Send us a text sourcing at the nucleus, grading for ROI, and dodging fakes. I unpack the full playbook from my Barcelona trip to find Messi rookies: why Campió (Catalan) issues matter vs Campeón (Spanish), the true 71 Bis story (third-edition BIS replacement → lower print + set-builder demand), and how Europe’s historic grading friction (pre-PSA EU) created today’s raw opportunity. I walk through Facebook ad targeting (40–55 men), peñas/outreach, euro/Bizum constraints, Spain-specific negotia...
