Boost Shake (Secret): Rarity & Collectibility
Boost Shake (Secret) 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 #229/203 of the SWSH07: Evolving 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 Boost Shake (Secret)?
In 2026, a Near Mint Boost Shake (Secret) (Secret Rare, SWSH07: Evolving #229/203) changes hands at roughly $2.23, and its scarcity does most of the heavy lifting on that figure. Because demand concentrates on clean copies, surface wear is punished hard: a Near Mint example commands about $2.23, whereas a Damaged one slides to around $1.47. Across the wear scale that reads Near Mint $2.23, Lightly Played $2.38, Moderately Played $1.72, Damaged $1.47 — proof that for a collectible like this, presentation is inseparable from value. At the very top, a gem-mint PSA 10 Boost Shake (Secret) is valued near $49.00 — about 22x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.
Graded Boost Shake (Secret): Gem Mint & Population
For a chase card like Boost Shake (Secret), the high-grade market is where the real money lives. A PSA 10 (or CGC 10 / BGS Black Label equivalent) Boost Shake (Secret) sits around $49.00 — roughly 22x 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 $4.25, CGC 10 $20.00, CGC 9.5 $10.00 — 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.
