Koga's Grimer: Rarity & Collectibility
Koga's Grimer 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 #078/132 of the Gym Challenge 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 Koga's Grimer?
In 2026, a Near Mint Koga's Grimer (Common, Gym Challenge #078/132) changes hands at roughly $0.96, 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 $0.96, whereas a Damaged one slides to around $0.33. Across the wear scale that reads Near Mint $0.96, Lightly Played $0.64, Moderately Played $0.67, Heavily Played $0.38, Damaged $0.33 — proof that for a collectible like this, presentation is inseparable from value. At the very top, a gem-mint PSA 10 Koga's Grimer is valued near $63.00 — about 66x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.
Graded Koga's Grimer: 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) Koga's Grimer sits around $63.00 — roughly 66x 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 $15.99, CGC 10 $35.00, CGC 9.5 $12.99 — 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.

Collector Outlook for Koga's Grimer
As a Common, Koga's Grimer earns its place through set completion rather than chase appeal — but a binder is never finished without it. Collect it for completeness and the joy of the hunt; its appeal is the set, not the ceiling. Whether you are chasing it for a set or as a centerpiece, revisit Koga's Grimer on RarePokemonCard — rarity demand in 2026 shifts with reprints, set nostalgia, and how few high-grade copies surface.
