500 Dīnār - Moẓaffar od-Dīn Qājār

Mozaffar od-Din Shah signed Iran's first constitution in December 1906, just months before his death — making the final years of his reign among the most consequential in Qajar history. This coin was struck during that charged period, when the Constitutional Revolution was already building pressure on the court. The shah's chronic illness and repeated European spa treatments, financed partly through Russian and British loans that mortgaged Iranian customs revenues, left the treasury perpetually strained.

KM#977 represents one of the smaller silver denominations of the Mozaffari coinage reform series.
