Released on June 1, 2001, Neo Discovery is the second main expansion of the Neo series, drawn from the Japanese Crossing the Ruins... set and exploring the mysteries of the Ruins of Alph alongside newly discovered Generation II Pokémon. The set features 75 cards introducing fan favorites like Politoed, Smeargle, Wobbuffet, and nine different Unown — each with unique effects tied to the letter they represent. As a key chapter in the Johto era that expanded the roster of Gold and Silver Pokémon in the TCG while adding the enigmatic Unown mechanic, Neo Discovery holds a special place in the Wizards-era collecting landscape. Here are the 10 most expensive cards from this expansion.
