Brock's Geodude (66): Rarity & Collectibility

Brock's Geodude (66) in its sought-after Unlimited variant sits at the most plentiful end of the rarity scale — easy to pull and easy to find. Cataloged as Common #066/132 of the Gym Heroes 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 Brock's Geodude (66)?

In 2026, a Near Mint Brock's Geodude (66) (Common, Gym Heroes #066/132) changes hands at roughly $0.59, 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 $0.59, whereas a Damaged one slides to around $0.32. Across the wear scale that reads Near Mint $0.59, Lightly Played $0.56, Moderately Played $0.41, Heavily Played $0.35, Damaged $0.32 — proof that for a collectible like this, presentation is inseparable from value. At the very top, a gem-mint PSA 10 Brock's Geodude (66) is valued near $52.18 — about 88x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.

Graded Brock's Geodude (66): 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) Brock's Geodude (66) sits around $52.18 — roughly 88x 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 $15.50, CGC 10 $12.50, CGC 9.5 $11.50 — 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.
