How do you make a money symbol?

How do you actually go about creating a money symbol? Is it as simple as drawing a dollar sign or is there more to it? Are there specific rules or guidelines that one must follow in order to accurately represent the concept of money through a symbol? Are there any cultural or historical factors that come into play when designing a money symbol? I'm curious to learn more about the process and the considerations that go into creating a symbol that effectively communicates the value and power of money.
