Hello and welcome to the forum.

Philippine Emergency / Guerilla Currency is listed in the "Special" volume of the Pick catalogue (Volume 1). This note is a 1942 series 1 peso from Leyte, listed as number S394 in the catalogue, with a recorded printing of 50,500 notes. My 1995 edition of the book lists it at $10 in Fine.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
