Watch List notes:

Arab-Sasanian Prototype Issue, Khusru II (A.D. 590 - 627), silver drachm or dirhem, (3.88 g), Darabgird mint, dated year 35 (A.D. 621), with word "praise" in outer margin, (cf.Walker alpha [p.2] Plate I, alpha, cf.M.21, Sellwood type 62, Gobl 214). Uneven patination, good very fine and scarce.

Ex M.J. Syddell Collection. The typical Sasanian bust of this coin became the standard bust type of Islamic drachms with governor's names. This type with the additional word in the outer frame also became the model adopted by the Umaiyad Governors using this Sassanian coinage model for these issues.
