Emperor of Annam, Thành Thái, with the Kim Khánh and Tien Source:Vietnam National Museum of History (https://baotanglichsu.vn/vi/Articles/3098/15571/hoang-dje-thanh-thai-vi-vua-yeu-nuoc-cua-vuong-trieu-nguyen.html)
This is a silver Tự Đức Thông Bảo (嗣德通寶) presentation coin weighing two mace, representing the fourth class within the hierarchy of this presentation issue.
The coin conforms to the traditional round shape with a square central perforation characteristic of the East Asian Sinosphere. The obverse bears the inscription ‘Tự Đức Thông Bảo’ (嗣德通寶). On the reverse, the characters ‘Nhị Nghi’ (二儀) are aligned vertically above and below the square piercing. Disposed to the right and left of the piercing are representations of the sun and moon, respectively, encircled by auspicious clouds. The term ‘Nhị Nghi’ originates from the I Ching (Classic of Changes), designating heaven and earth as well as yin and yang; by extension, it symbolises conjugal harmony and the nurturing of all creation, reflecting the intention of the Nguyễn rulers to imbue award coinage with cosmic order and Confucian social ethics.
Historically, gold and silver in Vietnam served principally as weighed uncoined bullion for large-value transactions and as media of exchange in external trade, whilst among the general populace they functioned predominantly as stores of wealth. Following the establishment of the Nguyễn Dynasty, the imperial court centralised minting authority, instituting a bimetallic monetary system in which standard cast copper-alloy and zinc cash coins (tiền chế) circulated alongside precious metals in the form of ingots and coins. With regard to precious metals, the authorities and merchants customarily cast them into rectangular ingots designated as nén, stamped on the upper surface with the imperial reign title in Chinese characters. When Spanish and Mexican silver dollars entered the Far East in immense quantities during the eighteenth century AD, Vietnam initially persisted in melting and recasting them into nén; only subsequently did silver and gold coins (tiền) gradually emerge. Following the dynasty’s foundation, the emperors placed paramount importance on utilising coinage as an instrument of political patronage and reward. Commencing with Emperor Minh Mạng, large commemorative copper coins bearing maxims from the Confucian classics (mỹ hiệu đại đồng tiền) and ‘flying dragon’ silver coins (phi long ngân tệ) were struck or cast to bestow favour upon meritorious officials, frequently adorned with hanging tassels to serve a dual function as honour medallions. Amongst these, the ‘flying dragon’ silver coins possessed a relatively low fineness despite their high nominal value, which incited widespread illicit counterfeiting and thoroughly discredited the currency—a circumstance that probably prompted subsequent monarchs to elevate the fineness of later presentation silver issues. As an insignia of honour, the tiền was generally subordinate in rank to the jade plaque (bội) and the sounding-stone pendant (khánh), though at times it ranked immediately below the khánh, suspended directly from its base. After the AD 1920s, in conformity with Western honour systems, these coins were occasionally worn suspended from ribbons. Beyond rewarding military or administrative merit, tiền were also distributed as commemorative honours on occasions such as the Lunar New Year, the Holy Longevity Festival (Thánh Thọ Tiết) celebrating filial veneration of the elderly, and the imperial jubilees marking the Emperor’s fiftieth, sixtieth, and seventieth birthdays.
In the sixth year of Thiệu Trị (AD 1846), the imperial court first authorised the minting of a five-tiered set of gold and silver coins comprising Nhất Nguyên (One Primal Origin), Nhị Nghi (Two Primal Forces), Tam Thọ (Three Longevities), Tứ Mỹ (Four Virtues), and Ngũ Phúc (Five Blessings). Following his accession in the first year of Tự Đức (AD 1848), Emperor Tự Đức (Nguyễn Phúc Thì) maintained this institutional precedent. In the sixth lunar month of that inaugural year, the Imperial Mint situated within the Armoury (Vũ Khố) of the Imperial Citadel of Huế cast the Tự Đức Thông Bảo (嗣德通寶) series of gold and silver coins utilising silver of 80 per cent fineness. This five-tier series increased incrementally in weight with the mace (tiền) serving as the unit of account: the first tier, Nhất Nguyên or Nhất Đức, weighed one mace (approximately 3.8 grammes); the second tier, Nhị Nghi, weighed two mace (approximately 7.35 to 7.5 grammes); the third tier, Tam Thọ, weighed three mace (approximately 11 grammes); the fourth tier, Tứ Mỹ, weighed four mace (approximately 14.5 grammes); and the fifth tier, Ngũ Phúc, weighed five mace (approximately 18 grammes). Provided that the prescribed fineness and official regulations were strictly observed, the authorities permitted private individuals to recast them, thereby rendering the demarcation between genuine imperial issues and private casts remarkably indistinct.
Emperor Tự Đức (Nguyễn Phúc Thì, born Hồng Nhậm) was the second son of Emperor Thiệu Trị (temple name Hiến Tổ). He acceded to the throne in AD 1847 at the age of nineteen, adopting the era name Tự Đức the following year (AD 1848), and reigned for thirty-six years (AD 1847–1883). Highly erudite and steeped in classical learning, he was one of the most culturally cultivated and accomplished Confucian scholars amongst the Nguyễn monarchs. Throughout his reign, he prioritised the civil service examinations for talent recruitment, personally debated canonical texts with senior court officials, presided over the compilation of the Khâm định Việt sử Thông giám cương mục (Imperially Commissioned Annotated Text and Commentary of the Comprehensive History of Viet), and authored works including the Ngự chế Việt sử tổng vịnh tập (Imperial Anthology of Odes on Vietnamese History). However, his governance was markedly conservative; in foreign affairs, he strictly enforced edicts proscribing Christianity and maintained a policy of national seclusion, severely penalising foreign missionaries and domestic Catholic converts. This provoked acute internal social unrest and afforded Western imperialist powers a pretext for armed aggression. Commencing in AD 1858, a joint Franco-Spanish fleet bombarded Tourane (Đà Nẵng) and seized Gia Định (Saigon), plunging Vietnam into an unprecedented colonial crisis. Subjected to unremitting military pressure, Emperor Tự Đức was compelled to sign the Treaty of Saigon in AD 1862, ceding the three eastern provinces of Cochinchina; looked on helplessly as French forces annexed the three western provinces in AD 1867; and ratified the Second Treaty of Saigon in AD 1874. Beset by domestic strife and foreign encroachments, he endeavoured to recover the lost territories through diplomatic negotiation and summoned Qing imperial forces to suppress regional rebellions and oppose French expansion, yet his efforts ultimately proved unavailing. Deeply afflicted by physical infirmity and imperial anxieties, he died in June AD 1883 at the age of fifty-five, leaving behind a severely weakened realm facing the progressive loss of its national sovereignty.
