Siebold (Japanese): Rarity & Collectibility

Siebold (Japanese) in its sought-after Holofoil variant is a Secret Rare — a top-of-the-set short print and one of the toughest cards to land in the wild. Cataloged as Secret Rare #091/070 of the S6K: Jet-Black Spirit 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 Siebold (Japanese)?

In 2026, a Near Mint Siebold (Japanese) (Secret Rare, S6K: Jet-Black Spirit #091/070) changes hands at roughly $3.06, and its scarcity does most of the heavy lifting on that figure. At the very top, a gem-mint PSA 10 Siebold (Japanese) is valued near $13.56 — about 4.4x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.

Graded Siebold (Japanese): Gem Mint & Population

For a chase card like Siebold (Japanese), the high-grade market is where the real money lives. A PSA 10 (or CGC 10 / BGS Black Label equivalent) Siebold (Japanese) sits around $13.56 — roughly 4.4x 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 PSA 9 $8.50 — 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.
