Shah Sultan Husain was deposed in 1722 when Afghan forces under Mahmud Hotaki besieged Isfahan for over six months, forcing the Shah to personally surrender the crown. This Mashhad issue dates to 1723 — after the fall of Isfahan but during the period when Safavid authority in the eastern provinces had not yet fully collapsed. Mashhad continued striking in the Sultan Husain name even as the dynasty was disintegrating around it.
The Type D classification distinguishes this from earlier abbasi formats through specific calligraphic arrangements documented in the Zeno reference corpus.
