Ninja Boy: Rarity & Collectibility

Ninja Boy in its sought-after Reverse_Holofoil variant is an Uncommon, slightly scarcer than the base cards but still widely available. Cataloged as Uncommon #103/114 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 Ninja Boy?

In 2026, a Near Mint Ninja Boy (Uncommon, XY - Steam Siege #103/114) changes hands at roughly $0.35, and availability keeps it within easy reach for collectors. Because demand concentrates on clean copies, surface wear is punished hard: a Near Mint example commands about $0.35, whereas a Damaged one slides to around $0.13. Across the wear scale that reads Near Mint $0.35, Lightly Played $0.26, Moderately Played $0.20, Heavily Played $0.28, Damaged $0.13 — proof that for a collectible like this, presentation is inseparable from value.
