Drachm - Buran

Buran — more formally Boran, daughter of Khosrow II — ruled for roughly two years across two separate stints, making her one of the last rulers of a dynasty in terminal collapse. She came to power amid the succession chaos that followed the Byzantine wars and the internal revolts that had already gutted Sasanian political authority. Her reign was unusual enough that later Islamic historians treated it as a curiosity worth noting: a woman on the throne of Iran, issuing coinage in her own name, at the precise moment the Arab conquests were beginning to move northward.

The Göbl classification places this among the final coherent royal issues before provincial governors effectively fragmented what remained of Sasanian minting.
