The inscription on the face of this coin is written in Pahlavi script ("nycky MLK"), with the principle control mark ("Sh") rendered upside-down. The reverse depicts a fire altar with attendants, each standing under six-spoked wheels (Mithraic sun wheel? Buddhist wheel of law?). This fire altar points to an interest in Zoroastrianism among the Hephthalites, most likely imported from the Sassanians. Whether they actually practiced this faith or merely imitated the motifs found on Sassanian coins cannot be determined.
