The origin of "$" can be traced back to the beginning of16th century, when Spain minted a silver dollar called "peso". This silver dollar pattern has a crown and a royal badge (lion and castle) on one side and two pillars on the other. According to western mythology, they are the pillars of Hercules, representing the peaks on both sides of the Gibraltar Strait.
According to legend, Europe and Africa were linked together a long time ago, and were later pulled apart by Hercules. 1732, Mexico city used a machine to cast a kind of "double-column silver dollar", and its figure was similar to "peso". It's just that the patterns of the eastern and western hemispheres are added between the two columns, and each column has a pattern curled into the shape of "$ $".
