Manaphy

Manaphy is a Water-type Pokémon that debuted in the Diamond & Pearl era and appears as a Rare Holo in the base Diamond & Pearl set from 2007. While Diamond & Pearl cards have gained some nostalgic appeal as the set approaches its 20th anniversary, most rare holos from this era outside of key cards remain relatively affordable. The complete lack of available pricing data suggests this particular card sees very little market activity and likely trades in the bulk category.
