Coin-swords (alternatively spelt as coin swords), alternatively known as cash-swords, are a type of Chinese numismatic charms that are a form of feng shui talisman that were primarily used in southern China to ward off evil spirits and malicious influences, especially those inducing fever. These coin-swords are also often used in Taoist rituals. Coin-sword is considered an "evil-warding sword" (Chinese: 避邪劍; pinyin: bì xié jiàn) in China. Coin-swords usually consist of Qing dynasty era cash coins, specifically from the Kangxi and Qianlong eras, but may also be made from older cash coins.
