These are traditional I-Ching Coins. They are also called Fu (good fortune) coins, Lucky Coins, or Tai Sui Coins. They are used in Chinese culture for many purposes, including celebrating the Chinese New Year, wedding ceremonies, and other festive events. It is believed that hanging these coins in your home or workplace can bring good luck, wealth, health, and prosperity to all who live or work there. Each coin is about the size of a U.S. dime and is made of metal. The coins are packaged in a red drawstring pouch. This is a great item for your own use or as a gift for someone else.
