How to read this value

What affects this card’s price?

The estimate above applies to the 1999 Pokemon Base Set #56 printing. A card with the same character or player from another set can have a very different value.

Condition and professional grade

Centering, corners, edges and surface quality can move a card between raw and graded price levels. A high grade should never be assumed from a listing photo alone.

Variant and exact print

Parallel, holo, reverse holo, first-edition and promotional versions may use different price records. Confirm the set and card number first.

Market activity

The source snapshot recorded 47 sales over 30 days. Compare recent listings and completed sales before buying or selling.
