Khosrow II King of Kings of Sasanian Empire from 590 to 628.
Khusro II was the last great king of the Sasanian Empire, reigning from 590 to 628.

He was the son of Hormizd IV (reigned 579–590) and the grandson of Khosrow I (reigned 531–579). He was the last king of Persia to have a lengthy reign before the Muslim conquest of Iran, which began five years after his death by execution. He lost his throne, then recovered it with Roman help, and, a decade later, went on to emulate the feats of the Achaemenids, conquering the rich Roman provinces of the Middle East; much of his reign was spent in wars with the Byzantine Empire and struggling against usurpers.

The script on the obverse within the circle to the left and right of the portrait translates to something like: "Khusro, may his glory grow"

The reverse script to the right of the right attendant near as I can tell the closest match translates to the Erankhvarrah-Shapur mint. I'm not 100% on this.

The script to the left on the reverse is the regnal year, but I could not match it against the examples on beast coins, which doesn't include every year, but includes several and all the above info which is very helpful with this confusing series.
