1 Qiran - Nāṣer al-Dīn Qājār Hamedān mint

Nāṣer al-Dīn Shah's long reign saw persistent inconsistency in provincial minting — Hamedān, operating as a regional mint rather than the central Tehran facility, produced coins with notoriously variable die workmanship and flan preparation. The 25-year window this type spans reflects not a continuous production run but intermittent striking, often tied to local commercial demand in the western Persian trade corridors connecting Tehran to Baghdad.

Hamedān mint issues of this period frequently show edge irregularities and off-center strikes that Tehran would not have tolerated.
