JAPAN KANEI TSUHO possible ridge pole ceremony coin


JAPAN, 1 mon, no date (1678-1868 AD), Obverse: KANEI TSUHO, “shin” new style, seems to be silver plated, 21.5mm, 1.65g, in a Fisher holder on which he misattrbuted it as “ancient China” and wrote “35% silver 15% gold.” I don’t think so, but it’s quite light in color. The characters are uniformly vertically compressed. Looks genuine. A colleague suggests that it might be a coin used in a ridgepole raising ceremony.aF

The Kanei Tsuho coins were first made in 1626 and was the only copper coin made in Japan for more than two centuries.

The Japanese took their idea of coinage directly from China making square holed cast bronze coins starting in the 8th century AD. The chinese had been making coins for 1300 years already so the Japanese could see what the benefits and problems were. There is the possibility given the rarity of the earliest Japanese coins and the existence of silver versions that the whole coinage thing started with a palace game of Let’s Play Chinese. My main reference is the book: Early Japanese Coins by David Hartill.

China calls itself “Central Country.” That is in reference to the vast Asian hinterland that is not China and to the island peoples out in the Pacific Ocean. Because China tended to do organizational things earliest in that part of the world the outsiders would notice and adopt useful practices that they observed. Among those borrowed cultural practices was the adoption of the money economy to replace direct barter or to replace less convenient shapes of metal rings and tools and jewelry bits. The Chinese style of market money being square holed cast bronze coins that became the form of the coins made in Korea Japan Vietnam the islands out to Java into Siberia and as far west as Kazakhstan.
