Zweilous: Rarity & Collectibility

Zweilous in its sought-after Reverse_Holofoil variant is an Uncommon, slightly scarcer than the base cards but still widely available. Cataloged as Uncommon #85/114 of the XY - Steam Siege set, it is the kind of card RarePokemonCard tracks for scarcity and collector demand rather than raw price alone. The harder a card is to pull in top condition, the more weight serious collectors place on it.

How Rare & Valuable Is Zweilous?

In 2026, a Near Mint Zweilous (Uncommon, XY - Steam Siege #85/114) changes hands at roughly $0.40, and availability keeps it within easy reach for collectors.

Across the wear scale that reads Near Mint $0.40, Lightly Played $0.25, Moderately Played $0.23, Heavily Played $0.22, Damaged $0.24 — proof that for a collectible like this, presentation is inseparable from value.
