This is a ½ Fueang copper coin issued between AD 1865 and 1866 during the reign of King Rama IV of the Chakri Dynasty, which ruled Thailand. Fueang was an historical Thai denomination, equivalent to one-quarter of a Baht.
The obverse of the coin features the royal emblem specifically associated with King Rama IV. It depicts an abstract representation of the Great Crown of Victory (พระมหาพิชัยมงกุฎ, Phra Maha Pichai Mongkut) at its centre, emitting radiant light from the top. This crown is one of the five royal regalia of the Chakri dynasty and symbolises the king’s divine authority, being worn only during coronation ceremonies. On either side of the crown are depictions of seven-tiered umbrellas, arranged in a tapering form resembling spires, each layer narrower than the one below. Originating from Hindu traditions, these umbrellas symbolise royal authority and protection over the people. The space between the crown and the umbrellas is filled with ornamental motifs, commonly floral and leafy patterns. These likely include palm leaves, the pink shower tree (Cassia bakeriana), and the golden shower tree (Cassia fistula), all of which are culturally significant flora in Thailand.
The reverse side features a chakra (चक्र), or wheel, an important symbol in Vajrayāna Buddhism. Surrounded by blade-like leaf forms, the chakra also serves as the weapon of Vishnu. The chakra is emblematic of the Chakri dynasty, from which the name “Chakri” is derived, and the Thai king is traditionally regarded as an earthly incarnation of Vishnu. At the centre of the chakra is an Asian elephant, likely a white elephant. In Vajrayāna Buddhism, elephants represent strength and wisdom. In Thai culture, the prestige of monarchs was historically associated with the number of elephants, particularly white elephants, they possessed. King Rama IV is recorded to have kept fifteen such elephants, many of which came from Sri Lanka. Today, elephants are recognised as national and cultural symbols of Thailand, frequently appearing in official insignia and artistic representations.
The left and right sides of the emblem display the denomination “½ F.” in Arabic numerals. Along the upper edge, a Thai inscription reads “สอง อัน เปน เฟื้อง” (two units equal one Fueang), while the lower edge bears a simplified Chinese inscription indicating the denomination: “方片二,” used here as a colloquial representation of “½ Fueang.”
In AD 1857, King Rama IV received a small manually operated minting press as a gift from Queen Victoria. Coins produced using this press were known as “tribute coins,” marking the beginning of machine-made coinage in Thailand. The system was later upgraded to steam power. In that same year, King Rama IV established the Royal Mint in the outer court of the Grand Palace in Bangkok. In AD 1875, King Rama V commissioned a new minting facility, and in AD 1876, new coins were issued. These coins adopted Western styles and featured, for the first time in Thai history, the king’s portrait, thus establishing a new tradition. Originally, the Baht was a unit of weight equivalent to 15 grams of silver. Following the fall in silver prices in AD 1902, Thailand informally adopted the gold standard, decoupling the Baht from silver and reorganising its monetary system.
King Rama IV (also known as King Mongkut, AD 1804–1868) was the fourth monarch of the Chakri dynasty. He reigned from AD 1851 to 1868 and is widely regarded as a pioneer of modernisation in Thailand. Prior to ascending the throne, he spent 27 years as a Buddhist monk, during which time he studied astronomy, mathematics, and Western knowledge extensively, acquiring a strong understanding of foreign cultures. During his reign, he actively promoted diplomatic relations with Western powers, including the signing of the renowned Bowring Treaty with Britain, which opened Thailand to international trade. Although the treaty placed certain limitations on Thai sovereignty, it enabled the country to avoid colonisation. Rama IV also prioritised educational and religious reforms, introducing Western-style education and scientific knowledge, while reorganising the monastic system and affirming the monarch’s role as the protector of Buddhism. He laid the foundations for Thailand’s modernisation and paved the way for further reforms under his son, King Rama V.
