What affects this card’s price?
The estimate above applies to the 1999 Pokemon Base Set #51 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
This record is marked as the Shadowless variant. Confirm that marking before using the estimate.
Market activity
The source snapshot recorded 6 sales over 30 days. Compare recent listings and completed sales before buying or selling.
