Notes
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.
