Interesting fact

One interesting fact about the 1 Ryō "Ansei Koban" coin is that it was minted during the Ansei era (1854-1860) in Japan, which was a time of significant cultural and economic change in the country. The coin's design, featuring the Chinese character for "correct" or "justice" on the reverse side, reflects the government's efforts to promote Confucian values and reform the currency system during this period.
