Richie,
The Nisfi or 1/2 Dam of Akbar as listed by Liddle for coins with dates either in neumerals or persian words as well as mint name are Agra, Ahmedabad, Akbarpur Tanda, Awadh, Bahraich, Baitata, Dogaon, Fatehpur, Gorakhpur, Gwalior, Hazrat Delhi, Hissar-Firoza, Kalpi, Lahore, Lakhnau, Narnol & Quannauj. There are other series of coins which are undated coins w/o mint names, coins w/o mint names but having dates and coins of Ujjain & Kashmir listed under different sub-headings.
The list on Numismaster includes, besides most mints listed by Liddle, Burhanabad, Ahmadnagar, Ujjain & Quannauj in the same list; though some mints from Liddle's list are not mentioned by KM.
This would definately show that fractional Dams of Akbar were not always minted by mints which minted Dams and also the fact that the coins were not as widely used as the Dams in those days.
