Japan, Kanei Tsuho, Edo Period, 1603 - 1868
In 1636, the Tokugawa shogunate introduced Kanei Tsuho coins to standardize copper coins and maintain a sufficient coin supply. These coins, the first government minted copper coins in 700 years, became the daily currency used for small payments. Although the Kanei era ended in 1643, coins continued to bear the Kanei Tsuho legend for 230 years. By the 1650s, 16 private mints were opened across Japan. The shogunate outsourced the mintage to regional and local merchants who cast them at varying weights and sizes, as well as occasionally having local mint marks. Kanei Tsuho produced before 1668, referred to as "old Kanei" coins, are recognizable by their consistent calligraphic style. Kanei Tsuho coins produced after 1668, "new Kanei" coins, have more diverse calligraphic styles. From 1738 government authorized iron Kanei Tsuho 1 mon coins, and in 1866 iron 4 mon Kanei Tsuho were authorized.
