I bought this coin...accidentally. At an open-air market in Tbilisi, Georgia, I picked up the coin at a stall to examine it, and then promptly dropped it on the concrete. It had survived hundreds of years, I suppose, relatively intact, then I knocked a lump off the edge, which you can clearly view. I asked the old Georgian man how much he wanted for it, without letting him know I'd already damaged it, then haggled him down to about thirty dollars. I was just glad it wasn't a few hundred or whatever. Anyway, it's about 18mm across, maybe 2 grams, and probably silver. More, I don't know. I'd love to know, what country? What period? And what language? Oh, and if you've got a link to the same coin in a better state. Thanks in advance.
I think it is from the Seljuks of Rum, probably Qilij Arslan IV, 2nd reign (655-664 AH/ 1257-1266 AD). Your coin is an almost perfect match for coin #1353 in Tim Wilkes' "Islamic Coins and Their Values, Volume I: The Medieval Period". Sorry, I can't find an online photo of this right now, maybe someone else can help with that. Looks like this is not a rare coin, but you have an interesting story to go with it, so that makes it valuable to you!
Thank you very much for the help. I've checked out the Seljuks, and Qilij Arslan IV, and that seems to be a match.
