Copper coins from the Kushan Province (the location of present day Kashmir) were analyzed by NAA at MURR, an investigation performed to study the changes in coinage over time. Very often the coins used during the former king's reign were restamped with the likeness of the new king, thus a recycling of the coins (and the ore they were made of) took place. In this particular study, we found that a different copper ore was used to produce coins for a successor king in the Kushan Province. This is very surprising. Where did this new copper ore come from?
