I also want to clarify something that I’ve been wondering for a bit now – all of the thick stamp 1st edition base set non-holo cards I’ve come across seem to have a sketchy 1st edition stamp, leading me to wonder if all thick stamp 1st editions are fake. Example image can be found below from a post on efour, in which the thin stamp wartortle seems to have a fake 1st edition stamp. Can someone confirm or negate my suspicions? There have been some thin stamps non-holos that have been graded by PSA. Example of a thin stamp is posted as well.
