Shah Alam Bahadur was a Mughal emperor who ruled the Mughal dynasty from 1707-1712 AD. He issued the coins in gold, silver, and copper. He also issued coins with his pre-accession name Muazzam; however, these coins are very rare.
This above shown gold Mohur of Shah Alam Bahadur was struck at Muhammadabad (Bidar) in 1120 AH. The obverse of this coin depicts the Persian legend in three lines ‘(Sikka Mubarak) Badshah Ghazi Bahadur Shah Alam’ with AH date in the top line. The reverse of a coin inscribed with Julus formula with a mint name at the top.
There were more than one places named 'Muhammadabad' during the Mughal period, but the placement of the mint-name at the top and general execution of the coin makes it certain that it was struck at Bidar in Northern Karnataka. Bidar was named 'Muhammadabad' in the early 15th century by Bahmani Sultan Muhammad I. It was renamed 'Zafarabad' during Aurangzeb's reign but reverted to its old Islamic alias towards the end of his reign.
