This is a bronze Thái Bình thông bảo coin issued under the Nguyễn Lords of Quảng Nam in Đại Việt (present-day central and southern Vietnam).
The coin follows the traditional East Asian typology of a round form with a square central hole. The obverse inscription reads “Thái Bình thông bảo” in a style between clerical and regular script, arranged vertically and read from top to bottom, right to left. The characters are relatively small. In the character “太”, the dot is slightly offset to the left and written as a slanted dot, not connected to the left-falling stroke. The character “平” features two dots rendered in a seal script-like style, but inverted vertically to resemble the form “┐┌”. In the character “通”, the radical “辶” is simplified, with the bending stroke reduced to a single vertical line, and the bottom right stroke combines the sweeping stroke and the final bend into one. On the reverse side, below the square hole, there are two small dots, a feature referred to as “two dots below the hole” (背下二星).
The attribution of the Thái Bình thông bảo coin is contested and diverse. The first scholarly reference appears in AD 1882 in Annam and its Minor Currency, published in Shanghai by Eduardo Toda y Güell, a noted archaeologist and then Spanish Vice-Consul in Macau, following his travels in East Asia. Toda believed that the coin originated from Lê Sùng (rendered as Le Tong), titled King of Cẩm Giang (Cam Giang Vuong), who was persecuted and executed in AD 1509 under the Later Lê Emperor Lê Uy Mục. His brother Lê Oanh (rendered as Le Ninh in Toda’s text, although Le Ninh was in fact the son of Lê Hựu, known as Emperor Lê Trang Tông), is said to have escaped prison, risen in revolt under Lê Sùng’s name, adopted the reign title “Thái Bình”, and minted flat-reverse Thái Bình thông bảo coins. This account is not recorded in official dynastic histories. Lê Oanh later recaptured the capital, ascended the throne as Emperor Lê Tương Dực, and adopted the reign title Hồng Thuận.
The reign title “Thái Bình” was used multiple times in history. In AD 966, during the final years of the Five Dynasties and Ten Kingdoms period, Đinh Bộ Lĩnh defeated the Twelve Warlords and established the Đại Cồ Việt kingdom—known in history as the Đinh dynasty. In AD 970, he proclaimed the Thái Bình reign and issued “Đại Bình hưng bảo” coins, with the character “Đinh” on the reverse. Later, in AD 976, the Song Emperor Taizong adopted the reign title “Thái Bình hưng quốc” and issued Thái Bình thông bảo coins with clerical-style inscriptions. It was common for private mints in Vietnam to borrow Chinese reign titles to issue their own coins, capitalising on the recognisability and circulation of Chinese cash coins. Such private minting usually occurred during periods of weakened central authority—such as the end of the Trần dynasty, the final years of the Later Lê dynasty, or from the reign of Cảnh Hưng (AD 1740–1786) onward. Moreover, during the Lê Restoration that overthrew the Mạc dynasty, the Mạc retained power in the border region of Cao Bằng and are believed to have issued their own Thái Bình thông bảo coins.
According to Japanese numismatist Okudaira Masahiro, “Thái Bình” might not refer to a reign title but rather serve as an auspicious term. The Nguyễn Lords of Quảng Nam, beginning with Nguyễn Hoàng, and his successors, are thought to have issued multiple types of Thái Bình thông bảo coins to meet commercial demand, resulting in a variety of minting styles. Historical evidence suggests that Nguyễn Phúc Trú (Ninh Vương) and Nguyễn Phúc Khoát (Võ Vương) of the 18th century both issued Thái Bình thông bảo coins featuring a dot on the reverse. French scholar Jules Silvestre also proposed that Mạc Cửu, a regional magnate in Hà Tiên under the Nguyễn Lords, minted extremely thin Thái Bình thông bảo coins, which were more likely gambling tokens than legal tender.
The Nguyễn Lordship of Quảng Nam began in AD 1558, when Nguyễn Hoàng—an early founder of the Lê Restoration—was appointed governor of Thuận Hóa at the suggestion of Trịnh Kiểm. Though framed as an honour, this appointment effectively exiled Nguyễn Hoàng to a frontier region, weakening his influence at court amid growing Trịnh dominance. At the time, Thuận Hóa was underdeveloped and served both as a buffer against Champa and Cambodia and as a frontier suitable for autonomous governance. Rather than resisting his assignment, Nguyễn Hoàng actively governed the region—recruiting migrants, pacifying local populations, building defences—and gradually established a de facto independent political and military regime known as the Nguyễn Lords of Quảng Nam. Although nominally loyal to the Lê emperor, they functioned independently and opposed the Trịnh-controlled northern court. From AD 1627, a prolonged civil war erupted between the Trịnh and Nguyễn, lasting until a truce in AD 1672, which formalised the Nguyễn’s control over central and southern Vietnam.
The Nguyễn Lords subsequently expanded southward, conquering territories from Champa and Cambodia. In AD 1698, they established the Gia Định prefecture, consolidating control over the Mekong Delta. During this era, the regime promoted Chinese-style education and civil service examinations, encouraged agriculture and Chinese immigration, and maintained social stability. However, by the late 18th century, corruption and heavy taxation provoked a popular uprising led by the Tây Sơn brothers in AD 1771. The Nguyễn Lordship was overthrown in AD 1777, with most of the royal family executed. Only Nguyễn Phúc Ánh survived, later founding the unified Nguyễn dynasty in AD 1802—the last imperial dynasty of Vietnam.
「太平通寶」鑄主的可能性多元,首次入譜當為公元1882年,由著名的考古學家,時任西班牙駐澳門副領事的愛德華多·托達·伊·古埃爾(Eduardo Toda y Güell),於遊歷東亞後,於上海出版之《安南及其小額貨幣》(Annam and its Minor Currency)。托達認為太平通寶來自受後黎朝黎威穆帝迫害的錦江王(Cẩm Giang Vương ,書中作金江王/Cam-Giang Vuong)黎漴(Lê Sùng,書中作黎宗/Le Tong),公元1509年被殺後,其兄弟黎瀠(Lê Oanh,原書作黎譓/Le-Ninh,但黎譓(Lê Hựu)實為黎昭宗名,而Le Ninh為黎昭宗子黎寧,即黎莊宗),越獄逃出京城,以黎漴之名起事,建號太平,鑄平背的太平通寶,此段於正史無載。後黎瀠率軍返京破城即位,是為黎襄翼帝,改元洪順。
