Great ID, @Essor Prof
Here's another example from Zeno that looks pretty similar.

I noticed that the weights of octagonal falus coins of Khudadad Khan of Kalat listed in Zeno vary considerably.
In Krause only a falus (KM#21) is listed (no half falus is listed), and the photo also looks similar to the two examples above. I suspect the original coin posted may be a falus of low weight. We should also keep in mind that hand-hammered coins may use varying dies and often vary in striking position on the flan, so I think the coin in question here is a good match to the examples in Numista and Zeno.
