This is an imitation Zhidao yuanbao, modelled on the coin cast under Emperor Taizong, the second emperor of the Northern Song, using his final reign title, Zhidao. During his twenty-one years on the throne, Emperor Taizong employed five reign titles in succession.
The coin takes the form of the traditional round cash coin with a square central hole characteristic of the Sinosphere. The obverse bears the inscription Zhidao Yuanbao in cursive script, read in clockwise order beginning from the top; the calligraphy is entirely derived from the emperor’s own hand. In the regular-script series, the character bao (寶) is said to have been simplified into three circular strokes, hence the nickname “Tortoise bao”. Apart from the script style, the cursive-script series corresponds to the regular-script series. This piece was probably produced by taking a circulating Northern Song Zhidao Yuanbao as the model, casting from it, and then further re-cutting the details by knife. The coin is relatively small, with a comparatively broad outer rim. It is rather rare; as an Annamese imitative trade coin, it is often unearthed together with Ming coin hoards. It was most probably produced by the Guangnan Kingdom, although coin moulds for Zhidao Yuanbao have been excavated at Võ Nhai in Thái Nguyên Province, Vietnam, so the possibility that it was instead made by the Later Lê dynasty, which was contending with Guangnan during the same period, cannot be entirely excluded.
Emperor Taizong of Song, Zhao Kuangyi, was the younger brother of the founding emperor, Zhao Kuangyin. Zhao Kuangyi’s succession is marred by the suspicion of fratricide, famously known as the “Candle Shadows and Axe Sounds” incident, coupled with several military failures during his northern campaigns against the Liao Dynasty. Consequently, he shifted his focus towards cultural endeavours, making it his mission to promote Confucianism. The two brothers, Emperor Taizu and Taizong, are often regarded as embodying the military and civil foundations of the Song Dynasty, respectively.
Emperor Taizu, during the Chunhua period (AD 990-AD 994), personally inscribed the calligraphy for the new currency “Chunhua Yuanbao,” making it the first coin in Chinese history to feature the emperor’s handwriting, known as “Imperial Script Money” (御書錢).
The coinage system of the Northern and Southern Song was complex. Officially circulating media included both copper and iron cash, complemented by paper money that functioned in mutual relation to them. The large-scale official adoption of iron cash was historically unprecedented in the Song, driven by shortages of copper ore and by frontier-region policies intended to prevent copper cash from flowing outward. Silver also gradually assumed an increasingly important role. Copper cash circulated in multiple nominal values, ranging from equivalents of one to ten. Coinage was cast by the various circuits according to local needs: some used only copper cash, others only iron, and others employed both. Calligraphic styles likewise varied, including regular, clerical, seal script, and “Slender Gold” script, among others. Although commonly described as “bronze”, the alloy in practice was typically a ternary mixture of copper, tin, and lead.
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.
