Square unit - Hunnic tribes Kidarites Sassanian style, 2nd version, Gandhara mint

The Kidarites were a Hunnic people who displaced the Kushans across Bactria and Gandhara in the latter half of the 4th century, and their coinage reflects that conquest in the most direct way possible: they simply copied Sasanian prototypes, adapting them to local striking conventions rather than developing independent types. This square copper issue belongs to a second design iteration, suggesting the Gandhara mint was already refining its output within a relatively compressed window of political consolidation.

Square copper fractions of this kind circulated alongside debased round issues in a region where monetary tradition was already fragmented across three prior imperial systems.
