Old Coins Japanese Ancient Coin No.4 ” Ryuhei Eihō 隆平永宝 “
The Ryūhei Eihō is the fourth copper coin in the “Twelve Imperial Coins,” Japan’s first series of coins, issued in 796 (the 15th year of the Enryaku era) by order of Emperor Kanmu. Minted against the backdrop of financial difficulties associated with the relocation of the capital to Heian-kyō, it was designated to be worth ten times as much as the old coins in circulation at the time, but in reality, it did not circulate smoothly.
