1 Cash - Chính Bình Thông Bảo

Chính Bình was the reign title of Trần Thái Tông, the first emperor of the Trần dynasty, who came to power after the Trần clan effectively engineered the collapse of the Lý dynasty through a series of calculated marriages and political maneuvers. This cash was produced during a period of significant administrative consolidation, as the Trần court reorganized the bureaucracy and military that would, within decades, repel three Mongol invasions. Barker's attribution to this reign remains the standard reference, though die consistency across surviving examples is poorly documented in Western literature.
