What affects this card’s price?
The estimate above applies to the 2016 Pokemon XY Steam Siege #28 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 2 sales over 30 days. Compare recent listings and completed sales before buying or selling.
