Safavid 1/2 Shahi?

Bought this coin recently, 4.6 gram, I think it is Isma'il I, 1501-1524, ½ shahi but not sure, there are versions from different cities.

I would appreciate more info about this coin.

I'm not too familiar with Isma'il I coinage.  However, I think you are correct and it is a .5 Shahi/1 Puli, A#2577.  I think the mint is cut off the bottom left of the flan.

My eyes must be playing tricks on me because I think I see some digits on the portion containing the Kalima, which is unusual.  

I couldn't find any too similar on Zeno but I think you're heading in the right direction.  

Best,

Mike
