4 Anna - Mir Usman Ali Khan

Mir Usman Ali Khan, the last Nizam of Hyderabad, issued coinage through the 1940s while simultaneously negotiating — and ultimately failing — to maintain independence from the newly formed Indian Union. When Indian troops entered Hyderabad in September 1948 in what the government called a "police action," the Nizam's monetary system collapsed almost immediately. Coins of this type, struck in the final years of his reign, circulated for an extremely short window before being demonetized.

The .818 silver fineness is specific to Hyderabad's own standard, distinct from both British India and later Republic India coinage.
