The value of a specific Mewtwo-GX card is determined by a confluence of factors, including its printing (e.g., standard, promo, full art), condition (graded or raw, with wear assessed using a standardized scale), and market demand. For example, a pristine, graded first edition Shining Legends Mewtwo-GX will command a significantly higher price than a more common, played version from a later set.
Understanding card valuation is crucial for both collectors and players in the Pokmon Trading Card Game. Accurate pricing facilitates fair trades and sales, protecting both buyers and sellers. Historically, certain cards, particularly rare and sought-after ones, have appreciated significantly over time, representing a potential investment opportunity. The interplay of rarity, artwork, and playability influences the long-term value trajectory of cards like the various Mewtwo-GX iterations.
