Keeladi, with its rich storehouse of antiquities, has hogged the limelight, especially with the recent finding of a punch-marked silver coin dating back to the ancient Maurya dynasty. The silver coin was a hidden treasure with symbols of sun, flower and Nandi. The ongoing phase of excavation, which took off in February and lasts till September, discovered over 1,200 antiquities and artefacts. But the silver punch-marked coin assumes greater significance.
