1 Qiran - Nāṣer al-Dīn Qājār Mashhad

Nāṣer al-Dīn Shāh's long reign (1848–1896) saw persistent monetary chaos — multiple mints striking to inconsistent standards, with Mashhad operating semi-independently in the northeast, closer to Afghan and Central Asian trade routes than to Tehran's administrative control. The Mashhad mint's output during this period frequently diverges in weight and fineness from nominally identical issues struck at the capital, a product of local assay practices rather than deliberate policy.

Album 2936.1 distinguishes the Mashhad attribution by specific die characteristics. Worth confirming against weight tolerance before assuming equivalence with Tehran-struck Qirans of the same regnal year.
