Off to Korea - North Korea - or the People's Democratic Republic of Korea. Weird thing about this coin. See that "견 본" on the obverse? That alternatively means, per my research, sample or specimen. Krause-Mishler (KM) doesn't talk about it; Schön (S) gives it a catalog number as a specimen. KM-1174 is this coin without the "견 본". S-1000.2 is this coin with the "견 본". I'm not sure if it's real, as in not a commercial fake, or maybe what we call in the west a 'specimen.'
