2 Tumân - Nāṣer al-Dīn Qājār Gold in Khorasan - Tehran mint

Nāṣer al-Dīn Shāh's long reign (1848–1896) saw persistent tension between centralized Tehran coinage and provincial mints operating with considerable autonomy. The Khorasan attribution here is significant — the eastern provinces regularly produced coins whose fineness and weight drifted from official standards, a chronic embarrassment to the central treasury. By the late 1870s, the government was actively consolidating mint authority, and issues dual-attributed to both a provincial origin and Tehran reflect that transitional administrative moment rather than any single striking location.

KM#940 is associated with a relatively brief window of production within the reign.
