Chinese coins were once currency in ancient China, so it makes sense that they represent wealth and abundance. They are considered one of the Eight Treasures along with the pearl, lozenge, stone chime, rhinoceros’ horn, mirror, book, and leaf, which are all symbols of good fortune and prosperity. These old Chinese coins are circular with a square punched out in the middle. The shapes of the coins are meaningful. The circle represents the influence of the heavens upon the earth, which is symbolized by the square.
