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 negotiation dynamics, and a fake-spotting checklist (stock, color, honeycomb, album lines). Final haul: 30 Messi rookies; 21 submitted to PSA with conservative grade bands and clear ROI math. Four raws sold in 24 hours—why liquidity + velocity matter more than perfection.
