1 Qiran - Nasir al-Din Shah Hamadan mint

Nasir al-Din Shah's reign of nearly fifty years was the longest of any Qajar monarch, and the Hamadan mint was among the provincial facilities that struck his coinage intermittently throughout that span. Output from Hamadan was never consistent — the mint operated under local supervision with variable silver supplies, which produced measurable differences in alloy fineness across the reign. The 1848–1896 date range on this type reflects the full theoretical window, but attributing a specific piece to a narrower period generally requires die study or regnal year reading from the coin itself.
