Every Market price in the app is what a card sells for right now, by condition.

  • Market prices update daily.
  • Pokémon (English and Japanese), Magic: The Gathering, Yu-Gi-Oh! and One Piece are covered, sealed products too.
  • Graded prices are for slabs, by grading company and grade.
  • Card details and pictures come from free card catalogs. A card from a search shows its price once you pick it.
  • When there’s no price for a condition, the app works it out from the Near Mint price.

Tap the ⓘ beside Market price on a card to see this in the app. Settings → About → Data sources & credits names every source.

In Inventory, Refresh prices (or pulling the list down) checks the prices that aren’t fresh any more. How often depends on your plan.

Prices are estimates, not offers. A price you type on a card always wins.
