The Colas c31.20

c31.20

These coins with a substantial gold content are, however, exceptional instances of the survival of old issues or very limited new issues minted from time to time; for the general history of Cōḷa currency seems to have been marked by a progressive deterioration. While the 'Ceylon type' issues of Rājarāja I are usually of fairly good gold, all the available specimens of later monarchs beginning from Rājādhirāja I are of very base gold, 'or rather silver washed with gold.'⁵²
