1 Kasu - Rajas of SivaGanga

Sivaganga's status as a semi-autonomous zamindari under the Nawabs of Arcot — and later under Company control following the Polygar Wars — left its coinage in a peculiar administrative limbo. The rajas retained the right to strike copper for local exchange even as silver and gold transactions increasingly flowed through British-controlled channels. This kasu represents that narrowing window of indigenous monetary authority, a window that effectively closed when the East India Company tightened its grip on the Carnatic after 1801.
