1 Cash - Quang Trung Thông Bảo, with An Nam

Quang Trung — born Nguyễn Huệ — ruled for barely four years before dying in 1792, likely in his late thirties, cutting short what had been a remarkably aggressive military and administrative program. He had seized the throne after leading the Tây Sơn forces that crushed a 29,000-strong Qing Chinese invasion at the Battle of Đống Đa in early 1789, a victory so swift the campaign lasted roughly five days. Cash coinage under his reign was issued in parallel with ongoing military consolidation; the "An Nam" inscription reflects his bid for Qing recognition of Vietnamese sovereignty, which Beijing ultimately granted posthumously.
