Tandemaus (Japanese): Rarity & Collectibility
Tandemaus (Japanese) in its sought-after Holofoil variant is a genuine Rare that print runs hold back, so collectors have to hunt for clean copies. Cataloged as Rare #317/190 of the SV4a: Shiny Treasure ex 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 Tandemaus (Japanese)?
In 2026, a Near Mint Tandemaus (Japanese) (Rare, SV4a: Shiny Treasure ex #317/190) changes hands at roughly $6.51, and desirability among set-builders keeps that number firm. Because demand concentrates on clean copies, surface wear is punished hard: a Near Mint example commands about $6.51, whereas a Moderately Played one slides to around $3.00. Across the wear scale that reads Near Mint $6.51, Lightly Played $6.58, Moderately Played $3.00 — proof that for a collectible like this, presentation is inseparable from value. At the very top, a gem-mint PSA 10 Tandemaus (Japanese) is valued near $42.95 — about 6.6x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.
Graded Tandemaus (Japanese): Gem Mint & Population
Even for a card at this rarity, the top of the market belongs to certified gem-mint copies. A PSA 10 (or CGC 10 / BGS Black Label equivalent) Tandemaus (Japanese) sits around $42.95 — roughly 6.6x a raw copy. That gap exists because relatively few examples ever earn a perfect grade, so gem-mint population is the real scarcity collectors chase. Step down a notch and demand spreads across CGC 10 $33.99, CGC 9.5 $18.00, BGS 9.5 $25.00 — each tier a smaller, scarcer pool than the one below it. The rule of thumb for collectors: the rarer the card, the more a certified high grade matters to its standing.
