The government issued 12 kinds of bronze coins from 708 to 958. The first coin was called a "Wadokaichin" the last coin was called a "Kengentaihou."
"Tensho-Obang" was a gold coin made by Hideyoshi Toyotomi. The fineness of this gold was high; it was one of the largest gold coins in the world.
Takenagashikin (Only existing specimen)
The "Takenagashikin," manufactured during the era of Hideyoshi Toyotomi, was made by pouring gold into a bamboo-shaped cast. This example was found in the Yodo River in Osaka in 1935.
Gold Coins Produced during the Meiji Era
Under the gold standard system, the Meiji government issued new coins to control and stabilize the circulation of currency after the Meiji Restoration. When coin design was discussed, it was initially proposed that the portrait of the emperor be used in the design. This proposal was rejected, however, for fear that the august portrait might be profaned in circulation. For this reason, the dragon design was used instead.
