Dialga GX (Secret): Rarity & Collectibility
Dialga GX (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 #138/131 of the SM - Forbidden Light 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 Dialga GX (Secret)?
In 2026, a Near Mint Dialga GX (Secret) (Secret Rare, SM - Forbidden Light #138/131) changes hands at roughly $80.54, 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 $80.54, whereas a Damaged one slides to around $18.33. Across the wear scale that reads Near Mint $80.54, Lightly Played $49.49, Moderately Played $38.70, Heavily Played $32.00, Damaged $18.33 — proof that for a collectible like this, presentation is inseparable from value. At the very top, a gem-mint PSA 10 Dialga GX (Secret) is valued near $299.90 — about 3.7x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.
Graded Dialga GX (Secret): Gem Mint & Population
For a chase card like Dialga GX (Secret), the high-grade market is where the real money lives. A PSA 10 (or CGC 10 / BGS Black Label equivalent) Dialga GX (Secret) sits around $299.90 — roughly 3.7x 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 $78.00, PSA 8 $57.00 — 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.
