Coin identification [opgelost]

I would appreciate some help with the identification of the coin pictured below.

This is my search, with 1 result ...

Click on 'Coins' tab above, which will show 'Search the coin catalog'

I already knew ١٠٠ was 100 so then I clicked on the icon on the right of the search box
and chose Arabic lettering and added ١٩٥٩ and ١٣٧٩ and all three found that coin.

Thank you ZacUK, firstly for your incredible speedy reply and secondly for the helpful search instruction!
