Coins from Iran

My grandfather's name was Nouroz Ali Taghikhani and my mother's name was Mones Taghikhani.

It all started with my grandfather that he has given two coins that were used in World War 2 back in Iran. When my mother was young, she took them from her father and she kept them then handed them over to me and I gave them to my son. I have searched online and found out that they were used in World War 2 and found out that they are valuable. This is amazing because it doesn't matter where you come from, you are still united with people in the war.
