This is a bronze coin bearing the inscription Thái Bình Thông Bảo, minted between AD 1558 and 1777 by the Nguyễn lords of Quảng Nam, a regime that, while nominally recognising the emperor of the Later Lê dynasty as sovereign, in practise ruled southern Vietnam with Huế as its capital.
The coin follows the traditional square-holed design modelled after Chinese cash coins. On the obverse, the inscription “太平通寶” (Thái Bình Thông Bảo) is engraved in regular script Chinese characters, arranged in the order of top, bottom, right, and left. The reverse side is plain, featuring no inscriptions or decorative elements.
According to the research of Japanese numismatist Okudaira Masahiro, the term “Thái Bình” (太平) does not refer to a reign title, but rather serves as an auspicious expression. Beginning with Nguyễn Hoàng, the founding figure of the Nguyễn lords of Quảng Nam, successive rulers continued to mint Thái Bình Thông Bảo coins to meet the demands of trade. As a result, these coins exhibit a wide variety of forms and styles, reflecting their prolonged and decentralised production.
The founder of the Nguyễn Lords of Quảng Nam was Nguyễn Hoàng, whose father, Nguyễn Kim, had been a key statesman of the Later Lê dynasty. During Nguyễn Hoàng’s youth, the Lê court was usurped by the Mạc dynasty, established by the warlord Mạc Đăng Dung. Although the Later Lê dynasty was later restored with the assistance of Nguyễn Kim, pushing the Mạc forces back to the northern frontier region near China (modern-day Cao Bằng), political tides shifted after Nguyễn Kim was assassinated. Power fell into the hands of his son-in-law Trịnh Kiểm, who began persecuting members of the Nguyễn family.
To escape Trịnh Kiểm’s political suppression, Nguyễn Hoàng requested and was granted governorship of the southern province of Thuận Hóa (modern Huế). There, he established an autonomous base of power, gradually expanding southward at the expense of the Champa Kingdom. This marked the beginning of a de facto divided Vietnam, with the Trịnh lords ruling the north and the Nguyễn lords ruling the south—a period known in Vietnamese history as the Southern and Northern Dynasties (Nam Bắc triều) division.
