"Tenpō Chōgin" 6 stamps ND

One interesting fact about the Tenpō Chōgin coin is that it was minted during a time of economic reform in Japan, known as the Tenpō period, which aimed to promote economic growth and stability by introducing new currency and monetary policies. The coin's design, featuring six stamps or seals, symbolized the six provinces of Japan that were united under the Tokugawa shogunate. Additionally, the use of Billon, a copper-silver alloy, in the coin's minting process was a departure from the traditional use of pure silver or copper in Japanese coinage, reflecting the government's effort to introduce more affordable and practical currency into circulation.
