5 Qiran - Naser al-Din Qajar

Naser al-Din Shah's exceptionally long reign — 48 years, the longest of any Qajar monarch — produced considerable variation within this issue, including multiple mint cities and dated strikes that allow specialists to track the gradual debasement of silver content toward the reign's end. The KM#836 type spans his entire rule, from his accession following the assassination of Mohammad Shah to his own assassination by Mirza Reza Kermani at the Shah Abdol-Azim shrine in 1896.

Pieces struck at the Tehran mint in the 1880s and after show measurably lower fineness than earlier issues, a direct consequence of chronic fiscal pressure from Naser al-Din's increasingly expensive European tours.
