Very nice, Amit. Here is my only Akbar. Jalal al-Din Muhammad Akbar (963-1014 AH / 1556 - 1605 A.D.) INDIA, Mughal Empire AR Rupee Dated AH987 Dar al-Sultanate Ahmedabad Mint 10.96g
Nice. The mint name is almost always off-flan on these. Yours clearly shows the distinct "Ahmada(b)a" part of the mint name, along with a bit of the epithet.
It should re-tone in time, especially if you live in a polluted city and leave it exposed. I have had some similarly overcleaned specimens re-tone in well within a year.
