Can anyone help me identify this 3 silver coins? [επιλυμένο]

Hello

Thank you in advance for the much needed help in identifying this 3 Silver (Arab i presume) coins 

First i think is from Ilkhanate (around 2mm and approximately 2.40 grams)

The 2nd one i presume Ottoman Empire (around 2mm and approximately 2.58 grams)

The 3th one probably Iran (around 1.75mm and approximately 4.97 grams)

The ottoman one:
III. Osman, AH1168, 5 para.

First coin is Ilkhan

Thank you very much,
I will try to find it if this is on numista, but this is a good path!

Can anyone help with the 3th one?

I'm pretty sure that the third one is an Iranian 1 Qiran of Nasir al-Din Shah, but I couln't find close examples on Numista. If you check the obverse of this (smaller) coin, the text is the same as on your example: N#57422 

This is also not a hundred miles away: N#85356

There are much more examples on Zeno's from the same ruler, you should check those as well:

I'm not sure about the mint (which is on the reverse). Maybe Ashtarabad https://www.zeno.ru/showgallery.php?cat=11220 or Tabaristan https://www.zeno.ru/showgallery.php?cat=11232 ?

Thank you very much!
