Minting of Kanei Tuho coins and Tessen coins was done in Zeniza (organization in charge of minting coins during the Edo period) of various regions such as Kameido in Edo and Shichijo in Kyoto, and many of such coins were Kochusen, coins permitted by the Edo bakufu (Japanese feudal government headed by a shogun), which were supposed to be used throughout the country, and therefore, these coins were usually not treated as a local currency.
