The Shunga dynasty came to power when Pushyamitra Shunga, a Brahmin general, assassinated the last Mauryan emperor Brihadratha during a military parade around 185 BC. The transition mattered for coinage: the Mauryan punch-marked silver karshapana system gave way to regional cast and struck copper issues under local authority, of which this Mathura-region piece is a product. Mathura operated as a significant commercial node on routes connecting the Gangetic plain to the northwest, and copper karshapanas from this zone circulated in a genuinely mixed monetary environment alongside remnant Mauryan silver.
