Symbol of money-$ double vertical bar

As we all know, $ stands for dollar. So how did it come from? One theory is that it is the evolution of the overlapping writing of private secretaries. Private secretary is the abbreviation of a round coin peso from 18 to 19 century in the United States. This kind of coin has been used all over the country since 1774 was formally established as a mint in the United States. Later, the American government recognized the symbol $ as the unit of the new currency, that is, one dollar. When writing, $ should be placed before the number. For example, USD 65,438+0 should be written as 1.50 USD 50 yuan RMB. And there is a little story behind this text.

It is appropriate that Irish immigrants in the United States are considered as one of the symbols derived from the dollar. Oliver Pollock sailed on the high seas at the age of 23 and settled in Carlisle, Pennsylvania. The young entrepreneur soon established his wealth and influence in the West Indies trade.

Pollock took action in Louisiana, where he gained more wealth as a businessman and planter. His success enabled him to provide materials for patriots in the revolutionary war cause and keep close contact with the influence of the US Congress. Pollock's success made it easy for him to buy military supplies to support it, because the Spanish Empire had an outpost in New Orleans, Louisiana. Pollock used his own currency peso when dealing with Spaniards.

In the real Spanish tradition, Puller uses the abbreviation of peso, but the abbreviations obtained in his calligraphy seem to be transposed letters "P" and "Di".

Before 1775, the monetary system of emerging countries was chaotic and needed to be reorganized. By 1775, the US Congress decided to correct the situation that supported it, which was the most common circulation. Coincidentally, Spanish coins were minted as legal tender in the New World. Americans began to trade with "Spanish dollars", which was later called "yuan". The "pound" that Americans got rid of is a relic of British rule.

Congressman Robert Morris, who gave him Pollock billing records and continued to use the dollar symbol, was the first senior government official to bless him with "S" through these two routes.

In the printing of dollar symbols, there appeared 1797 proposed by defender Li Benshu, which indicated that the dollar was accepted as a pure American symbol.
