I agree with Robert that heir hypothesis is poor
This person has a crown with eagle
. The eagle
was a symbol of Anahit.
In Catologue SNS of Israel I find information: "....opposite the two busts small bust with left profile on a frontal bust; crown cap adorned with eagle's head...."
. Thus this person is not clear, but some light give the description of reverse
this coin: ".... to the left of the altar attendant with stylized crown of Wahram II, right hand extended towards Anahita, left hand resting in scabbard, to the right of the altar attendant with stylised crown of Anahita, handing over diadem wreath to Wahram II."
Please notice that this person on ther reverse
has the same crown like small person on the obverse
. Thus, maybe Anahita? What do you think?
