Spectrometric studies of Pb coins of the Kshatrapa period which were recovered at Nagara, India indicated that almost the same metallic impurities are present in the coins as in galena ore from the Aravalli region: thus, the ore for the coins was probably mined at the Aravalli region. The Indian Pb metallurgical industry was thus shown to be at least 16 centuries old. Quant. Chem. Anal. Of the coins indicated that the Pb was not alloyed with other metals to increase hardness.
