1/2 Tumân - Ahmad Qājār

Ahmad Shah acceded to the Peacock Throne in July 1909 at eleven years old, following the deposition of his father Mohammad Ali Shah, who had shelled his own parliament. The regency period produced administrative chaos, and coin issues from these early years show inconsistent striking quality across the Tehran mint — not as a design choice, but as a direct consequence of disrupted oversight during the constitutional crisis.

KM#1067 spans only the first two years of Ahmad's nominal reign before the regency formally ended in 1914.
