Confucian coin charms are a category of Chinese and Vietnamese numismatic charms that incorporate messages from Confucian philosophy into their inscriptions. Generally these amulets resemble Chinese cash coins but contain messages of the traditions, rituals, and moral code of Confucianism, such as the idea of "filial piety" (孝) and the Confucian ideals of "righteousness" (義). During the 19th century these Confucian messages were also featured on a number of 1 mạch Vietnamese cash coins during the Nguyễn dynasty.[1]
