EASTERN SISTAN: Anonymous Khusro type, ca. 680s-700s, AR drachm (3.78g), SK (Sijistan), year 85, A-P76, standard type and normal legends, but distinctive local style, with a pellet added to the left and right of the crown's wings, bold strike, VF-EF, RR. The "5" of the date is very clear (Pahlavi PNC), followed by either HSh for the beginning of "80" or ShS for the start of "60", but by style the year 85 seems more likely, presumably the Hijri date.
Estimate: 140-180 USD
