1 Tangka 'Vartula Tangka', single circle / single circle

The Vartula Tangka takes its name from the Sanskrit word for "round," distinguishing these mechanically struck pieces from the hand-hammered debased issues that had plagued Tibetan currency through much of the early 18th century. This specific type, catalogued under C#5.2 with its single-circle / single-circle format, dates to the brief window of Sino-Tibetan monetary reform following the Qing intervention of 1750–1751, when Beijing pressed Lhasa to regularize coinage after years of politically motivated debasement by the Dzungar-backed administration.

Production was centered at the Dode mint near Lhasa. The run was short.
