BI Square Unit - Anonymous

The Western Satraps — Iranian-descended rulers who controlled much of Gujarat and Malwa for roughly three centuries — issued anonymous billon squares as a fractional currency running parallel to their better-documented silver drachms. These pieces circulated without royal attribution, likely serving regional or small-transaction functions where the prestige of a named ruler was irrelevant to the exchange.

Pieper 838 is a recognized reference point, but the series remains poorly die-studied relative to the named coinage.
