Can someone please point out the date on this coin? According to the lot description, it is AH646. I can't seem to figure out exactly how to read the date on these. I see some characters that have potential, but I can't be certain. The picture is from a Heritage lot. I have a similar coin that I bought from Heritage.
The Seljuks had a tendency not to write proper arab numbers. Making them hard to read for a non-specialist like me. The margin text in your upper picture reads "This dirham was struck in Sivas". The date is in the margin on your lower picture. On the left is "Sitt" for 6, The bottom seems to read "Sitt'a" as short for 6 hundred. So the right should be fourty, though i do not really distinguish it as such. usually there is "wa" for "and" between the elements of the number. Here those are absent.
