What affects this card’s price?
The estimate above applies to the 1999 Pokemon Base Set #88 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 13 sales over 30 days. Compare recent listings and completed sales before buying or selling.
