1 Tumân - Nāṣer al-Dīn Qājār Type R, Kirmanshahan Mint

Nasir al-Din Shah's early coinage reforms of the 1850s were driven partly by pressure to stabilize Iran's currency after decades of debased silver issues had eroded commercial confidence. The Kirmanshahan mint served a strategically critical western corridor — the city sat astride the main route between Baghdad and Tehran, making locally struck gold essential for trade and troop payments near the Ottoman frontier. Provincial mint output from this period was tightly controlled and often short-lived, which keeps survivors genuinely scarce.
