Double X's 1933 Goudey card from his back-to-back MVP seasons. Foxx hit 534 career home runs and had one of the most feared right-handed swings in baseball history. His 1932 season (.364, 58 HR, 169 RBI) is among the greatest offensive years ever.
From a collection estate sale. The seller is asking $365 for this card. Current market comps suggest a value of $500. There's real profit potential here.

Flip Tips
Most cards sell within 10% of market on eBay. Getting 20%+ below is a genuine deal.
eBay charges ~13%, COMC ~20%. A 15% discount might mean zero profit after selling fees.
No selling fees at card shows. If you can sell in person, your margins improve dramatically.
Rookies have the most liquidity. Non-RC vintage may take weeks to find a buyer.
Frequently Asked Questions
What is Flip of the Day?
Flip of the Day is a daily card collecting challenge. Each day we feature one sports card with a deal price from a realistic buying scenario — card shows, estate sales, garage sales, or online marketplace listings. You vote whether you'd buy the card to resell (FLIP) or pass on the deal (SKIP). After voting, you see the community consensus and your potential profit or loss. It's a fun way to sharpen your card pricing instincts and learn what makes a good flip.
How is the daily card selected?
The daily card is algorithmically selected using a date-based seed, meaning everyone sees the same card on the same day. Cards are drawn from our database of 8,000+ real sports cards across baseball, basketball, football, and hockey. The deal scenario (card show find, estate sale, garage sale, etc.) and discount percentage are also deterministically generated so the experience is consistent for all collectors.
How is profit calculated?
Profit is calculated as the difference between the card's estimated market value and the asking price. If you vote FLIP, we calculate your potential profit by subtracting the asking price from the market value. The sell platform breakdown shows your net profit after fees on each platform (eBay 13%, COMC 20%, Mercari 10%, MySlabs 8%, Card Show 0%). Real flipping also involves shipping costs and time, which aren't factored into the base calculation.
What do the verdict ratings mean?
STRONG FLIP means the deal offers 40%+ ROI — a genuine steal that most experienced flippers would jump on. DECENT FLIP means 20-40% ROI — a solid deal with comfortable margin. MARGINAL means 5-20% ROI — barely profitable after fees, only worth it if you can sell at a card show (no fees). SKIP IT means under 5% ROI — the margin is too thin to justify the effort and risk.
Are the deals based on real market data?
The card values are based on real estimated market prices from our database. The deal scenarios are simulated but represent realistic buying situations that collectors encounter regularly — card show tables, estate sales, local card shop clearance bins, and online marketplace listings. Use this as a training tool to develop your instinct for spotting good deals in real life.
