Collecting Focus
“The hobby rewards patience and punishes emotion. Set your exit price before you buy, and stick to it.”
Prized Card
2018 Luka Doncic Prizm Silver PSA 10
$8,500
Bought raw for $200 on eBay in 2019 when Luka was still "just a Euro league guy." Graded PSA 10. Could have sold for $50K in 2021 but held. Still my best ROI at 4,150%.

Marcus's Top Tips
Buy 2-3 weeks before the NBA/NFL draft — prices spike 200-400% on draft night
Never hold a player through their second season unless they show superstar trajectory
PSA 10 pop report is your friend — low pop + high demand = premium
Set price alerts on eBay. Patience gets you 30-40% below market on any card
Daily Routine
Check eBay sold comps at 7am. Scan @CardPurchaser and @SportsCardInvestor on X. Review my watchlist on CardVault. Submit 10-15 bids by noon. Ship sold cards at 3pm.
Hot Take
Baseball cards are the most undervalued asset in the hobby right now. Basketball is overpriced relative to the size of the sport globally.
