6 Shahi - Nader Afshar Type C, Isfahan Mint

Nader Shah's monetary reforms of the 1730s were unusually systematic for a ruler who came to power through military force rather than dynastic inheritance. The 6 Shahi denomination was part of a deliberate restructuring of the Safavid monetary system Nader had inherited — and largely dismantled — following his effective seizure of control in 1732 and formal coronation at the Mughal-style assembly on the Moghan plain in 1736. Isfahan, the old Safavid imperial capital, continued striking under Afsharid authority partly as a statement of legitimacy, the mint's prestige carrying political weight Nader could not afford to abandon.

The "Type C" designation reflects a die revision within a short window — 1737 to 1739 — that ended with Nader's catastrophic Indian campaign reshaping the empire's bullion supply entirely.
