Every Pokémon card carries a rarity symbol.

The higher the rarity and the smaller the print run, the more a card is worth on the market.

Collector tips

  • Check condition (centering, corners, edges, surface): a near-perfect card can be worth far more once graded PSA 9 or 10.
  • Within a set, the full-art, secret and alternate-art cards hold most of the value — prioritise those.
  • Protect valuable cards with sleeves and toploaders to preserve their condition over time.
  • Prices move constantly: track each card and your whole collection live with PixelBinder.
