VALUE
What is Impostor Professor Oak #73 from Base Set worth?
Two different numbers answer this, and they are not interchangeable. Raw/ungraded: a loose, ungraded copy of Impostor Professor Oak #73 (Base Set) carries a market reference of $5.77 USD for the normal printing (TCGplayer market price, as of 2026-09-11). Graded slabs: a graded example is priced per grading company and per grade and can sit far above that raw figure - our own graded marks for this card are charted and tabled below, per grader and grade. Both are references, not offers. The graded copy in our machine carries a Rip Station estimated slab value of $188.60 (PSA 9).
