I happily received a nice persian drachm lately - my second one for now. They are not my main interest but it is nice to also add some of romes enemies to my ancient collection. The details on it are of good quality but I dont have much experience in identifying these coins so I'am here to ask you if there is a good side like wildwinds.com for persian coins and/or if you can help me with the identification of this example. Thanks in advance for your help and feel free to post some of your own persian drachms!
You can tell the kings apart by the different types of headdress. Try Zach Beasly's page for a start...Sasanian Coins.
Khusro II Looks to be Shiraz mint...Year 33. Nice Detail! Khusro II AR Drachm. Bust right, wearing mural crown with frontal crescent, two wings, and star-in-crescent, ribbons and crescents on shoulders; monogram behind head, stars flanking crown, double border, star-in-crescents in margin. Fire altar with ribbons; flanked by two attendants; date in Pahlavi to left, mint to right. SK (SISTAN, Zarang) mint, dated RY 37 (AD 628). Göbl II/3, Pl. no. 212. 4.14g, 33mm, 2h.Extremely Fine.
I see @Spaniard has already correctly identified the mint and date for this coin (I usually do that for Sasanian coins around here, but I was out enjoying spring bird migration). The kings are usually identified by their distinctive crowns, though if you're feeling ambitious you can also read their names in front of the portrait. The reverse of most Sasanian drachms lists the mintmark and date- the mintmark is on the right-hand side, the date is on the left. To ID these, see the useful pages created by the late Tom Mallory: https://www.forumancientcoins.com/numiswiki/view.asp?key=Sasanian Mints https://www.forumancientcoins.com/numiswiki/view.asp?key=Sasanian Dates
Thanks again for the good advice everyone, the thing about the sassanian crowns is very interesting. They really seem to have made a new crown for every king.
