Persia/ Zand Dynasty AV 1/4 Mohur Ashrafi AH 1195 (1781) Unlisted RRR Kerman Mint Sadeq Khan 1779-81 ( He was murdered by Ali Murad Khan) who then became Shah.
Nice, my only real regret in regards to the SINCONA auction is that the Gold Mohur of Karim Khan Zand has that big scratch on the reverse, his Mohur (I have the 1/4 one) is one of the coins I want to buy the most and they seldom come up for auction.
Yes, Kian is a Persian name, so it would be logical to assume that he was a prominent Iranian collector of Iranian coinage, but I can't find any information about him.
