I recently purchased a group of "Ancient" coins that I am trying to Identify (confirm). I have minimal information that was provided for each coin, but I am having trouble verifying the information provided, and filling in the gaps. I will list them each separately for help with these.

Information provided is India, Bahamani Sultanate - Ala Al Din Bahman, Half Falus. I couldn't match it to any listings in the catalog. The coin is 1.6 grams, and 6 x 7mm. Metal composition unknown.
Thank you in advance for any help with this coin. Colin
