History
Gold coins were minted in units of the ryo, based on the scaling system followed by Koshu gold coins minted under Lord Takeda of Kai province (now Yamanashi Prefecture) See: Dynasties (Japan). Keicho gold coins consisted of the oban (10 ryo), which served primarily as a reward or for ceremonial purposes, and the koban (one ryo) and ichibu-kin (1/4 ryo), which were issued as a means of exchange in daily life. The oban was exchanged according to gold content rather than face value, and was valued at approximately 7.5 ryo.
