The record carries no HP for it — Trainer cards do not print one. Its binder neighbours are Devolution Spray (#72) and Item Finder (#74). Impostor Professor Oak was printed without a holofoil panel; 16 of the 102 cards carry one. By checklist position it is 73 of 102, which puts it in the last third of the binder.

Which printing you are holding

Which Impostor Professor Oak you are holding is decided before grade is: the set ran in three printings. 1st Edition carries the edition stamp and a flat frame; Shadowless drops the stamp and keeps the flat frame; Unlimited restores the drop shadow. Priced, Impostor Professor Oak would carry one cell per printing — blending three print runs into one median states a price no one paid.
