I am selling this collection of notes from WWII. I must admit I am not familiar with the grading system for currency, so the buyer will have to judge for themselves. They are called a B Type Yen or Sen as noted by the large B in the center of each note. They are from Series 100. The currency was "issued pursuant to military proclamation" as stated on the backs. From what I have researched this currency was used by the people in the Okinawa Prefecture from 1945 when the United States occupied the region. It was the only legal currency for the Japanese at that time and location. The notes appears to be in excellent condition to me - used little if at all. There are no creases or dirty areas. The notes measure about 3"" x 2.5". You will receive a One Yen, a Ten Sen and a Fifty Sen note.
