Taihei Genpo

Japanese: 大平元宝 - たいへいげんぽう

Ancient Japanese coins. Silver coins. This was the second time silver coins were issued after the Wadokaichin, and none were issued in ancient times after that. An imperial decree in March 760 (Tenpyo-hoji 4) ordered their issuance along with the Kaiki Shoho money coins and the Mannen Tsuho copper coins. At the time, the legal value was set at 1 Taihei Genho coin equivalent to 10 Mannen Tsuho coins, and 10 Taihei Genho coins equivalent to 1 Kaiki Shoho coin. There are no historical documents showing that either the Taihei Genho or the Kaiki Shoho coins were subsequently circulated, and they were not used as currency. The only two known to date are one that was traded between antique and old spring dealers in Kyoto and Osaka, and one that was discovered in the sutra repository of Toshodaiji Temple in 1928.

Japanese:

日本古代の銭貨。銀銭。銀銭の発行は和同開珎についで2度目であり，これ以後古代では発行されていない。760年(天平宝字4)3月の勅によって，金銭開基勝宝，銅銭万年通宝とともに発行が命ぜられた。その際，法定価値は，大平元宝1枚が万年通宝10枚に相当し，大平元宝10枚が開基勝宝1枚に相当するものと定められた。大平元宝，開基勝宝は，ともにその後流通に関する史料がなく，貨幣としては用いられなかったらしい。その現物としては，京･大阪の古物･古泉商の間で取引された1枚と，1928年唐招提寺経蔵で発見された1枚の計2枚がこれまで知られているもののすべてである。
