Professor Oak's Research: Rarity & Collectibility
Professor Oak's Research in its sought-after Reverse_Holofoil variant is an Uncommon, slightly scarcer than the base cards but still widely available. Cataloged as Uncommon #149/165 of the Expedition 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 Professor Oak's Research?
In 2026, a Near Mint Professor Oak's Research (Uncommon, Expedition #149/165) changes hands at roughly $19.99, 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 $19.99, whereas a Damaged one slides to around $0.40. Across the wear scale that reads Near Mint $19.99, Lightly Played $8.43, Moderately Played $4.78, Heavily Played $2.00, Damaged $0.40 — proof that for a collectible like this, presentation is inseparable from value. At the very top, a gem-mint PSA 10 Professor Oak's Research is valued near $96.00 — about 4.8x the raw copy, the clearest sign of how much collectors pay for flawless scarcity.
Graded Professor Oak's Research: 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) Professor Oak's Research sits around $96.00 — roughly 4.8x 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 $99.99, CGC 10 $255.00, PSA 8 $14.50 — 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.
