AFSHARID: Shahrukh, 1st reign, 1748-1750, AR double rupi (23.25g), Mashhad, AH1161, A-2773, evenly struck, nice VF. This unusually heavy denomination was perhaps an attempt to introduce an alternative to the increasingly popular Spanish American 8-real, along with the Dutch leeuwendaalder (lion dollar), German and Austrian thalers, and the Ottoman piastres (kurus).
Estimate: USD 90 - 110
