I was cleaning the house and found these in a box of old stamps. They're all yellowed with age. The 7-yen postcard is from 1970. There are 103 postcards in total, as shown in the photo. Breakdown: 50-yen New Year's postcards: 15 40-yen official postcards: 8 40-yen postcards: 37 41-yen postcards: 7 20-yen postcards: 20 10-yen postcards: 8 7-yen postcards: 8 Total value: 3373 yen. Are there any collectors interested?
