Quang Trung — born Nguyễn Huệ — ruled for only four years before dying in 1792, possibly from a stroke while planning a second military campaign against Qing China. He had already routed a 200,000-strong Qing invasion force at the Battle of Đống Đa in 1789, one of the most decisive Vietnamese military victories on record. His Tây Sơn regime issued coins under the Quang Trung era name, though the dynasty itself remained perpetually cash-strapped and administratively fragile throughout his reign.
The công designation indicates a specific casting workshop or quality grade within the production run. Toda 197 places this squarely within the Tây Sơn series rather than the later Nguyễn dynasty issues that would follow after 1802.
