(1500-1680) Japan Echigo Province Gold Koban AU
Dating from a transformative era in Japanese history between 1500 and 1680, this gold Koban represents a fascinating chapter in regional currency. Minted during the Edo period, this substantial gold piece contains 0.4 troy ounces of gold and carries the denomination of 1 Ryo. Unlike centralized coinage, this specific issue was produced locally in the Echigo province under the authority of regional feudal lords. The obverse of this gold coin displays a striking arrangement of treasury seals and official validation stamps, carefully struck in a circular pattern across the surface. These marks served as a guarantee of weight and purity in the regional marketplace. In stark contrast to the detailed stamping on the front, the reverse of the coin was left entirely blank. Preserved in Almost Uncirculated condition, this historic treasure offers a direct connection to the feudal economy of early modern Japan.
