Interesting fact
One interesting fact about the 1 Ryo "Sado Koban" coin is that it was minted during a time of great economic change in Japan. The coin was introduced during the reign of Emperor Nakamura (1709-1736), who implemented a number of economic reforms aimed at stabilizing the Japanese economy and increasing trade with other countries. The introduction of the 1 Ryo coin, which was made of gold and had a standardized design, was part of these reforms and helped to establish a more stable and reliable currency system in Japan.
