1 Anna - Mir Usman Ali Khan

Hyderabad under Mir Usman Ali Khan, the last Nizam, operated one of the few genuinely independent mints in British India — the state maintained its own coinage rights as part of its treaty relationship with the Crown, a privilege most princely states had long since surrendered. Production of this type spanned the years leading into Indian independence, after which the mint's authority became politically untenable.

The Indian Union's annexation of Hyderabad in September 1948 — Operation Polo, a 108-hour military action — ended coinage under the Nizam's authority abruptly. Pieces struck in the final years of this series saw minimal circulation in some districts as hoarding and political uncertainty disrupted normal commerce.
