The Five Most Valuable Cards in Pokémon’s Aquapolis Set

Espeon #H9

Kyoko Umemoto’s Espeon opens the list with one of the warmest backgrounds in the set, a vibrant blue that suits the Pokémon perfectly.

It plays as cleverly as it looks. The Energy Return Poké-POWER lets you pull Energy back to your hand as often as you like before attacking, helping fuel its Damage Blast.

As one of the most collected Eeveelutions in the hobby, Espeon holds steady demand, with graded 10 copies commanding around $11,000 and ungraded copies trading near $300 depending on condition.

Mint raw examples are getting harder to source as master-set builders quietly pull them off the market.

Tyranitar #H28

Naoyo Kimura gives this pseudo-legendary a striking treatment, posing the Armor Pokémon against a darkened, star-dusted sky that rewards the holo foil beautifully.

A 120-HP Stage 2 powerhouse armed with Tail Slap and the Energy-hungry Gigacrush, Tyranitar has long been a fan favorite, and its Aquapolis card ranks among the set’s most desirable Holo Rares.

Condition is everything here, like with most vintage holos, mint cards are scarce. Graded 10 copies command around $10,000, while ungraded copies trade near $350.

Crystal Nidoking #150

The more attainable of the set’s two Crystal headliners, Hironobu Yoshida’s Crystal Nidoking still carries serious prestige.

Its Crystal Type body shifts to match Grass, Lightning, or Fire Energy, and the crystalline holo frame gives this Stage 2 card an almost prismatic presence in the binder.

As one of just three Crystals in the entire set, it’s the gateway grail for collectors chasing the subset, more reachable than Lugia, but a long way from common.

Graded 10 copies can sell for around $15,000, while ungraded copies go for $500.

Umbreon #H29

If any card challenges the Crystals for collector affection, it’s Umbreon. Illustrated by Mitsuhiro Arita, the artist behind the legendary Base Set Charizard, this Moonlight Pokémon gazes into a star-flecked night that makes the holo shimmer come alive.

Its Dark Moon Poké-POWER is pure disruption, letting you peek at your opponent’s hand and shuffle cards back into their deck.

As arguably the most beloved Eeveelution in the hobby, Umbreon commands strong demand in every grade. Graded 10 copies fetch around $14,000, while ungraded copies trade near $650.

Crystal Lugia #149

No surprise at the top. Crystal Lugia is the crown jewel of Aquapolis and one of the most coveted Lugia cards ever printed.

Illustrated by Naoyo Kimura, who also gave us the Tyranitar earlier on this list, it pairs a beloved legendary with the rarity and mystique of the Crystal subset. And the foil shifts gorgeously in the light.

Its value reflects that status, with graded 10 copies commanding around $75,000, with standout examples climbing even higher than that. Clean ungraded copies still trade in the four figures, while heavily played raw examples turn up for a few hundred dollars.

For collectors chasing a single grail from the e-Series, this is the one.
