1 Cash - Quang Trung Thông Bảo

Quang Trung — born Nguyễn Huệ — ruled for only four years before dying in 1792, likely in his early forties, cutting short what had been one of the most militarily decisive reigns in Vietnamese history. His 1789 rout of a Qing Chinese invasion force at the Battle of Đống Đa, achieved largely through a surprise Tết offensive, remains a celebrated episode in Vietnamese national memory. Cash coinage under his reign was issued from a state still consolidating power after the Tây Sơn rebellion, with administrative infrastructure rebuilt almost from scratch across a fractured monetary system.
