Ngun, also transliterated ngeun, is a Thai word that means both ‘silver’ and ‘money’. This dual meaning is illustrated in this ancient Chinese Double Dragon coin, where both concepts are intertwined.

This Double Dragon Tael Silver Coin, dating from the Guangxu era (1875-1908 AD) of the Qing Dynasty, was minted in Guangdong (廣東), often referred to as Kwangtung in historical contexts.

The coin features an intricate design on the obverse with two dragons chasing a flaming pearl, symbolizing imperial power and prosperity, giving it the name ‘Double Dragon’ coin. At the centre is a stylized circular form of the character for bat (fig.), a symbol for good luck as the pronunciation of fu (fig.), the Chinese word for ‘bat’, echoes the sound of the word foo (fig.) which means ‘good luck’. The reverse side includes inscriptions in Chinese characters, indicating the weight, i.e. one tael, approximately 37.5 grams, and purity of the silver. The upper text is separated from the inscription below by images of bats, which are Chinese symbols of good luck, while at the centre are Manchu characters, i.e. the script of the ruling class of the Qing Dynasty. Minted in high-purity silver, the coin was part of China's efforts to standardize currency and facilitate international trade during the late Qing Dynasty. Its historical significance, rarity, and detailed design make it highly valued among collectors, with well-preserved specimens commanding high prices in the numismatic market.
