Thank you. This is very useful for identifying those mosques, especially the first three . The later ones are very interesting. One of them is an historic attempt to prove that Crimea is in Ukraine, not in Russia. ( I won't comment here on which I think is more true).
I was still wondering about the one coin we have not identified. There is no design there to help us, it is just calligraphy, This suggests a strict Muslim régime, so I thought of Iran. It is from Iran. It is a 10 rials, isuued in a year in the range 1979 - 1982 AD .
