English: A faithful reproduction of a 1728 scroll from the Sendai Domain that the depicts the manufacture of copper cash coins in Japan. "After the coins are broken off the "tree" then they are placed on square rods and filed down so that the edges are smooth as possible. The two men in the center are filing the outside edges of the coins, while the man on the left is filing the inside square hole. This is time consuming and expensive to do, so one mon coins from the late Edo period are frequently not filed as carefully as earlier coins. In terms of care of production the 1660's was probably the apogee of Japanese cash coin manufacture. It is interesting that this coincides with the apogee of Tokugawa and daimyo lord authority as well. From the mid-eighteenth century producers learned how to make more coins faster and more cheaply but all in all the quality declines. The Sendai mint pictured here had excellent quality control and made beautiful coins even in the eighteenth century." - Dr. Luke Shepherd Roberts.
