Humayun, Silver Rupee, 11.30g, Bengal issue, Laknur / Lakur Mint, undated, Obv: In circle “Muhammadi Humayun Ghazi bi-Lakur/Laknur”; in the margin, Arabic legend “al-Sultan al-Azam al-Khaqan” followed by invocation “Khallada Allah Mulkahu”, Rev: Shahada in circle, followed by Arabic legend “yariqu man tasha'e adl bighayr hisab” (He elevates whomever He wills, justly without reckoning); names and titles of Rashidoon caliphs in margin (Abu Bakr Siddiq, Umar Farooq, Uthman Dhu Noorani, Ali bin Abi Talib) (G&G# B953). Very fine, extremely rare.
The coins of Laknur / Lakur mint are probably the rarest of Humayun’s short lived Bengal campaign issues. It is not certain where exactly Laknur was located but it is plausible that it was the same Lakhnauti, the old capital of Bengal. The coins thus are testament to Humayun's maximum penetration into the province but he was quickly ousted by Sher Khan (later Sher Shah) Suri.
