Dirham 'Dang' - Berdi Beg Saray al-Jadida mint

Berdi Beg's reign lasted barely two years before he was killed by his own brother Qulpa in 1360, inaugurating the catastrophic succession crisis that Timurid and Russian chroniclers would later call the "Great Troubles" — a twenty-year span during which the Golden Horde burned through more than a dozen khans. Coins struck at Saray al-Jadida under Berdi Beg are consequently confined to a narrow window, and the mint's output dropped sharply as political instability disrupted the lower Volga trade networks the Horde depended on for bullion supply.

The reduced weight of this issue relative to earlier Jochid dirhams reflects a debasement trend already underway before the succession crisis accelerated it.
