William & Marry, Silver Rupee, 11.51g, Mumbai mint, RY 4. Test marks and counter-marks on both sides (P. Steven# 1.25). Fine+, extremely rare. Since the British had occupied the island of Bombay but had no currency of their own to trade. Hence they thought of issuing their own currency based on the Mughal Rupee pattern. Consequently, they issued these coins in the name of their Emperor William and Queen Mary. But this was strongly opposed by the Mughal Emperor Aurangzeb on the ground that they did not take his permission to issue their own coins and they did not have any local standing. Consequently, the mintage of these coins was stopped. Coins of RY 4 are exceedingly rare.
