The 20 yen coin (二十圓硬貨) is a former denomination of the Japanese yen. These coins were minted in gold, and during their lifespan were the highest denomination of coin that circulated in the country. The first coins were minted in 1870 following the introduction of a decimal currency system. Twenty Yen coins spanned three different Imperial eras before mintage was halted in 1932. Many of these coins were melted down as a result of the wars between 1931 and 1945. These coins no longer circulate, and are instead collected as items of numismatic value, or as investments for their gold content.
