This is a brass coin cast and circulated in the first year of Cảnh Thịnh (AD 1793), under the reign of Nguyễn Quang Toản, the last emperor of the Tây Sơn dynasty. This charm, known as Cảnh Thịnh Thông Bảo, was likely issued to commemorate the change of reign title and may have been minted in Phú Xuân (present-day Huế), the capital at the time.
Due to years of continuous warfare and a devastated economy, although the court made efforts to collect copper materials from the populace and mint currency, the craftsmanship and quality could not be maintained. Furthermore, given the intense internal power struggles and declining central authority, mint officials, casting sites, and furnaces were difficult to control. Consequently, the coins produced during this period exhibit significant variation in design, shape, weight, and decorative features.
The coin adopts the traditional fang kong yuan qian (square-holed round coin) form characteristic of the Sinosphere. The obverse bears the inscription Cảnh Thịnh Thông Bảo in standard script, to be read top-bottom, right-left. The strokes are bold and thick. Surrounding the inscription is a dual-ring design: an outer rim and an inner ring, with a meandering pattern between them. The surface of the coin features a decorative motif of dragons and fish. The dragon’s horns resemble those of an ox or a deer, and it bears whiskers like a catfish. The dragon’s head is positioned above the central square hole, with its whiskers hanging down along the left side. Its scaly body extends from the upper right of the square and fades into the background. A spread claw is visible to the right of the square. Fish leap from the lower left and lower right quadrants. The remaining background is filled with stylised water and wave patterns. Within the Sinosphere, dragons symbolise imperial authority; however, the specific symbolism of the dragon and fish motif during the Cảnh Thịnh era remains uncertain and warrants further study.
Nguyễn Quang Toản, known posthumously as Emperor Cảnh Thịnh, was the son of Nguyễn Văn Huệ (Emperor Quang Trung), the founding monarch of the Tây Sơn dynasty. He ascended the throne in AD 1792 at the age of ten, with real power held by regents such as Vũ Văn Dũng, Trần Quang Diệu, and Bùi Đắc Tuyên. During Nguyễn Văn Huệ’s reign, the administration was marked by extensive reform: a six-ministry bureaucratic system was established, commoners and military achievers were promoted to office, land redistribution and tax simplification were implemented, all contributing to social stabilisation. Militarily, he prioritised the development of firearms and naval power, and in AD 1789 personally led a successful campaign against the Qing army at the Battle of Đống Đa, compelling the Qing court to recognise his regime and grant him the title “King of Annam,” thereby establishing a brief tributary relationship.
However, upon Nguyễn Quang Toản’s accession, he failed to maintain his father’s political and military authority. Factional struggles within the court intensified, governance became inconsistent, and the Nguyễn claimant Nguyễn Phúc Ánh (later Emperor Gia Long of the Nguyễn dynasty), rising from the south with French support, gradually defeated the Tây Sơn forces. In AD 1802, he captured Thăng Long (modern-day Hanoi). Emperor Cảnh Thịnh fled north to Lạng Sơn, seeking aid once again from the Qing court, but to no avail. He was captured shortly thereafter and is believed to have either committed suicide en route to captivity or been executed. He died at the age of twenty, marking the end of the Tây Sơn dynasty.
