500 Dīnār - Nāṣer al-Dīn Qājār

Nāṣer al-Dīn Shāh ruled Iran for nearly half a century before being assassinated in May 1896 by Mīrzā Reżā Kermānī, a follower of the pan-Islamic reformer Jamāl al-Dīn al-Afghānī. These final years of his reign saw the Qājār court hemorrhaging revenue through ill-considered concessions sold to British and Russian interests — the Tobacco Regie crisis of 1891 had already triggered a mass boycott that forced the Shāh into a humiliating reversal and left the treasury deeper in debt.

The concession-driven fiscal strain directly affected minting consistency during this window, and weight adherence across Qājār silver of the period is notoriously variable.
