That premium reflects how much collectors value high-grade copies of this specific card Pikachu collectors building master sets pay aggressively for clean copies because the cards edges and centering are notoriously hard to grade well

SR Super Rare Gishki Shadow X WATER Level 4 [ Sea SerpentEffect ] ATK 1200 DEF 1000 If you Ritual Summon exactly 1 WATER Ritual Monster with a card effect that requires use of monsters, this card can be used as the entire requirement

What also makes this card so valuable isnt the detailed background or even Raging Bolt ex itself it also helps that Raging Bolt ex is one of the best decks in the format, making this Pokemon much more valuable
