$is used as a symbol by many other uses, such as $, Hong Kong currency symbol HK$, Singapore currency symbol S$, etc., but usually refers to the UNITED STATES DOLLAR, commonly known as the UNITED STATES DOLLAR, is the currency of the UNITED STATES, for USD.
The origin of the “$” goes back to the early 16th century, when Spain minted a silver dollar called the PESO.
The silver dollar has a crown and royal emblem (lion and castle) on one side and two columns on the other.
According to Western mythology, they were the pillars of Hercules, representing the peaks on either side of the Strait of Gibraltar.
Legend has it that long ago Europe and Africa were connected, and then Hercules pulled them apart.
In 1732 Mexico City was machine-minted a “two-pillar silver dollar” with a pattern similar to the PESO.
Only between the two columns added the pattern of the east and west hemispheres, two columns on each of the curled into a “$$” -shaped graph.
Over time, people will see “$” as the sign of silver dollars.
Up to now, there are still many countries in the world using “$” as the symbol of their currency. Therefore, sometimes to distinguish the currencies of these countries (regions) (including the United States), the English name abbreviations of the country (regions) will be added before” $”, such as US dollar (USA$), (CAN$), and (HK$).
“$” can be written directly without causing ambiguity.
There are many theories about how this came to be, of which two are more common.
According to one theory, the symbol was formed by placing a narrower U over a wider S, so it represented the United States.
Another theory is that it is an evolution of the PS superposition.
PS is short for the Pesos, an American round coin of the 18th and 19th centuries that was used throughout the country until 1974, when the U.S. mint was officially established.
Later, the U.S. government recognized the $symbol as a unit of the new currency, the dollar.
When writing, put the $in front of the number.
If you write $1, you write $1. If you write $50 you write $50.
