This 2004 Pokémon Japanese Groudon ex #056 originates from the Undone Seal expansion and has been graded Gem Mint 10 by PSA. Out of all examples submitted to PSA, only 55 have earned this perfect grade. Japanese cards from the EX era are highly condition-sensitive, characterized by delicate silver-foil borders that are exceptionally prone to chipping and edge wear, making Gem Mint copies exceedingly scarce. The card features artwork by Hikaru Koike, portraying the continent-creating Legendary Pokémon against a crimson, starry holographic background that seamlessly integrates with the era's signature reflective border.
Undone Seal—the Japanese counterpart to the EX Hidden Legends set—is a milestone release from the Ruby & Sapphire era, focusing on the deep mythology of the Hoenn region. As an 'ex' card, it represents the high-stakes mechanic of the era where increased HP and stronger attacks were balanced by the opponent taking two Prize cards upon knock out. Mechanically, this Groudon ex is notable for its 'Ancient Sign' Poké-Body, which specifically disables the attacks of rival legends Kyogre ex and Rayquaza ex, a direct gameplay nod to the iconic elemental conflict of the third generation.Show more
