I'm hoping to get more info to identify these coins. I believe two are from Japan and the other from Taiwan, but that's all I have so far.
Here I have two Chinese coins. The 20 cash is in rough shape, but I still liked it enough to pay a quarter for it.
№ 5 & 3 - Taiwan; № 4 - 20 cash from one of a Chinese provinces; № 2 - 1 sen 1944 or 1945 (Japan); № 1 - 5 sen (Japan).
No. 3 is a "20 cent" (er jiao) coin dated 1950 (39th year of the Republic) from Taiwan. No. 5 is a "5 cent" (wu fen) coin dated 1936 (25th year of the Republic) from China. This is a Chinese "20 cash" coin which the Tianjin mint began producing in 1905. Gary
It's a one jiao ("10 cent") coin dated 1970 (59th year) from Taiwan (Republic of China). A similar coin may be seen here. Gary
