The top two coins are Chinese. The left one is a yuan feng tong bao cash coin written in seal script and cast during the years 1078-1085 of the reign of Emperor Shen Zong of the Northern Song Dynasty. The right one is a dao guang tong bao cash coin cast during the years 1821-1850 of the reign of Emperor Xuan Zong of the Qing (Ch'ing) Dynasty. It is difficult to read the reverse side but I believe the coin was produced at the Board of Revenue mint in Peking (Beijing). The bottom coin is Japanese. I am not familiar with Japanese coins at all but I think it is a kuan ei tsu ho cast during the period 1626-1859. Gary
The Japanese is one of the shin-kanei tsuho, from the Ashio mint. I do not yet have the specialist book for these coins, but it appears to be the same variety as one in my collection - cast Kanpo 1 (AD 1741).
