The Sports-Card Flippers App

Every raw card is a bet. Know which ones to grade.

Log your raw-card queue and SlabCall tells you, card by card, whether grading still clears breakeven — or whether it's time to sell raw before the market catches up.

Start your queue

The math changes every week. Your queue doesn't check itself.

Submission fees are real money, and every new population report quietly erodes a card's grading premium. A card that cleared breakeven last month might not clear it today — but nobody has time to re-run that math by hand across a growing pile of raw cards.

How it works

  1. Log the card. Player, set, year, variant, cost basis.
  2. Add comps. A recent raw sale and a recent graded sale — SlabCall does the rest.
  3. Get the call. Grade now, hold, or sell raw — recalculated as new data comes in, with an alert the moment it flips.
