The mysterious portrait on the reverse of this interesting issue has been identified as the heir apparent Khosrau I, an unknown satrap, or even Kshatra Vairya, the third of the great six "divine sparks" of the creator Ahura Mazda. It is worth noting that in the Gathas, the hymns composed by Zarathushtra, Kshatra Vairya is the guardian of metals.
