Who among the following has issued the coin rupee for the first time ?

Sher Shah Suri (1540–1545 AD) is credited with the introduction of the silver coin known as the 'Rupiya', which is the precursor to the modern Indian rupee [t2][t7]. While the term 'rupya' had been used generically for silver coins previously, Sher Shah formally established it as a standardized currency weighing approximately 178 grains (11.66 grams) to replace the older billon tanka [t3][t6]. This reform introduced a tri-metalism system consisting of the silver Rupiya, gold Mohur, and copper Dam [t2][t3]. This currency system was so robust that it was adopted and maintained by the Mughal Empire, including Akbar, and later by the British East India Company until 1835 [t5][t6]. In contrast, Muhammad-bin-Tughluq is known for his experiments with token currency and the 'Adali', while Alauddin Khilji utilized the 'Tanka' and 'Jithal' [t1][t5].
