Mir Jafar Ali Khan Bahadur was the first Nawab of Bengal under British influence. He was the second son of Sayyid Ahmad Najafi.
Mir Jafar pretended loyalty to Alivardi Khan's successor Siraj-Ud-Daulah but betrayed him to the British in the battle of Plassey. After Siraj Ud Daulah’s defeat and subsequent execution, Jafar achieved his long-pursued dream of gaining the throne and was propped up by the British East India Company as puppet Nawab.
This above shown silver rupee was minted in the reign of Mir Jafar. The obverse of the coin is inscribed with Persian legend which read as ‘Sikka Zad Bar Haft Kishwara Saya Fazl Hami Deen’ with AH date. The reverse of the coin is read as ‘Zarb Jahangirnagar Sikke Mubarak Julus Mainamat Manus Sanah 5’ with rosette mint mark.
