Shame, I thought I was answering the question of the milled 'Surat' rupee. (Abhinumis his symbol).
In my earlier post I already described it as 'Alamgir II'. So regard the above message as not written.
Nevertheless to solve Abhinumis his confusion, he has been looking under Bombay mint. Under transitional mints, Surat is given, but that part of the webside is still not completed and can't be consulted.
My description of September 7th, therefore is still valid : It's a rupee in the name of Alamgire II. It's not an issue of the British East India Company, but of the Nawab of Surat.
The British took over the control of the Nawab's mint at Surat in May 1800. From than onwards the fixed Ry.46 of Shah Alam II is put on the coins.
