    • Abstract


      Three types of Vishnukundin coins belonging to Andhra region were subjected to chemical and microstructural studies. The source of the ores used, the nature of the alloy and the techniques employed have been inferred from the data obtained. Trace elemental data have shown that the coins were made of unrefined metal which was also confirmed by electron microprobe results.
