Post-Mauryan coinage refers to the period of coinage production in India, following the breakup of the Maurya Empire (321–185 BCE). The centralized Mauryan power ended during a Coup d'état in 185 BCE leading to the foundation of the Shunga Empire. The vast and centralized Maurya Empire was broken into numerous new polities. In the east, the newly formed Sunga Empire utilized the industries pre-established in Pataliputra.
