1 Shahi Sefid - Ahmad Qājār

Ahmad Shah was thirteen years old when he ascended the Qajar throne in 1909, and his reign — nominally spanning to 1925 — was largely one of regency, foreign occupation, and institutional collapse. The small silver shahis struck under his name circulated during a period when British and Russian spheres of influence effectively partitioned Iran, and the central government in Tehran struggled to maintain any fiscal coherence. The Constitutional Revolution had already gutted the authority of the crown, and these coins circulated alongside a chaotic mix of foreign currency and older Qajar issues that the government lacked the means to retire.

Ahmad was formally deposed by Reza Khan in 1925 while abroad in Europe, ending the dynasty. He never returned.
