The guy he’s middlemanning for is the same as @pkmnflyingmaster mentioned. A.f.a.i.k. that collector (whoever it is) has eight out of ten SNAP cards in his possession, all graded by PSA. Only the Magikarp and Pikachu are missing, which are the only two pkonno hasn’t put up for sale on Yahoo Japan yet.
Anyway, good luck in your search! Those are some solid offers, since the raw one that was bought from pkonno2002 in 2018 went for 1.5M JP. Yen (~13k USD excluding fees).
