Though there is a picture of only one coin, the others are similar in grade. Being old and hand made, there are micro-differences to all of them.

The central government designated the city of Nagasaki as the only point of contact for the Vietnam trade. In 1659 production of special coins was allowed, and the Genho Tsuho coins were made until 1685.

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.
