This coin belongs to the period of Syed Mir Jafar Ali Khan Bahadur, who occupied the masnad of Bengal following the Battle of Plassey in 1757 with decisive backing from the British East India Company. By the time of AH 1172 / RY 6, Mir Jafar’s authority had already been reduced to a largely nominal position, while real political and military control rested firmly with the Company.

Although coinage continued to be struck in the name of the Mughal emperor Alamgir II, imperial sovereignty in Bengal had become purely symbolic. Mir Jafar functioned under the dominance of Robert Clive, marking the consolidation of British power in eastern India. The Azimabad (Patna) mint—then administratively linked to Bengal—issued rupees bearing the distinctive trident (trishula) mint mark, generally understood as a local or regional mint symbol. Rupees of AH 1172 / RY 6 with this mark are historically significant and considered scarce, reflecting the transitional phase from Mughal–Nawabi authority to effective Company rule.
