Why is the dollar sign - $ ?

Answer 1

The sign is attested in business correspondence between British North America and Mexico in the 1770s as referring to the Spanish-Mexican peso. The piastre was known as "Spanish dollar" in British North America, and in 1785, it was adopted as U.S. currency, together with both the term "dollar" and the $ sign.

The sign's ultimate origins are not certain. The most widely accepted explanation, according to the U.S. Bureau of Engraving and Printing here, is that "$" is a corruption of the letters "PS" or "PS" (for 'peso', as each letter could represent each syllable of "Pe-So") written over each other in Spanish. Eventually, the 'P' was reduced to a vertical line.

Another possibility is that it derives from the British notation 8/ for eight shilling, referring to the Spanish 8 reales coin ("piece of eight"), which later became the USA dollar. Others derive it from the Portuguese Cifrão sign . In Spain it is said that the sign of the old spanish peso "$" is the left Hercule's Column with the emblem of "Plus Ultra" that appears in the kingdom's Scutcheon of the Spanish Flag.Still another explanation holds that the dollar sign is derived from (or at least inspired by) the mint mark on Spanish colonial silver coins ("real" or "piece of eight") that were minted in Potosí (in present day Bolivia). The mint mark was composed of the letters "PTSI" superimposed on one another, and bears an undeniable resemblance to the single-stroke dollar sign (see picture). The Potosí mine is generally accepted as having been the largest single silver strike in history. Silver coins minted in Potosí would have been in common use in colonial America, and its mintmark widely recognized.

Earliest usage wrote the sign with a single vertical stroke. For some time, the double-stroke symbol was common, but is now again falling out of use.

(1) Many suggestions have been made about the origin of the dollar symbol $, one of the commonest being that it derives from the figure 8, representing the Spanish 'piece of eight'. However, it actually derives from a handwritten 'ps', an abbreviation for 'peso' in old Spanish-American books. The $ symbol first occurs in the 1770s, in manuscript documents of English-Americans who had business dealing with Spanish-Americans, and it starts to appear in print after 1800. Here is another version of the theory, which covers your source and the one above: (2) The Dollar Sign $ - Theories of its Origins Since the symbol is more recent than the name, and the origins of the latter are well understood, one might expect that the origins of the sign would also be known for certain particularly when the origin of the British pound sign, £, which is far older, is well-established. However that is not the case with regard to the dollar. Perhaps this is less surprising when there has been controversy over the origin of the sign for the European euro, €, a currency that did not come into existence until 1999. (It has been claimed that the euro sign was invented by Arthur Eisenmenger more than a quarter of a century before the currency was introduced). Nevertheless a number of theories about the origin of the dollar symbol have been proposed. The United States Abbreviation Theory One of the most popular theories is that the dollar sign is derived from the initials of the United States. If you superimpose a capital "U" on a capital "S" then drop the lower part of the "U", what you end up with is a version of the dollar symbol with two strokes. This theory was endorsed by the American libertarian philosopher and staunch defender of capitalism, Ayn Rand, in her novel Atlas Shrugged. Chapter 10 is entitled the Sign of the Dollar. Rand claimed the dollar sign was the symbol not only of the currency, but also the nation, a free economy, and a free mind. The Peso Abbreviation and Piece of Eight Theories However, a more widely accepted theory nowadays is that the sign owes its origins to the Spanish peso. One version of this theory is that the standard abbreviation of "peso" was simply "P", but the plural form was a large "P" with a small "s" above it and to its right. This was simplified by retaining only the upward stroke of the "P" and superimposing the "S" upon it. Hence the symbol of the dollar. See: Dreyfuss, Henry Symbol source book : an authoritative guide to international graphic symbols. New York : McGraw-Hill, 1972. If the peso abbreviation theory is the correct one why is the US dollar sign sometimes written with two vertical strokes? A possible explanation is that the best known Spanish Peso coin had two pillars engraved on the reverse side to symbolise the "Pillars of Hercules" at Gibraltar and the words "Plus Ultra" indicating that beyond the Pillars of Hercules there were other lands. That coin was called the Pillar Dollar in the British colonies in North America and the two pillars may have become the two strokes in the Dollar sign.

Answer 3

It is only appropriate that an Irish immigrant to the United States be the one credited with originating the dollar sign. Oliver Pollock sailed the high seas at the age of twenty-three, and settled in Carlisle, Pennsylvania. This young entrepreneur rapidly established himself as a wealthy and influential West Indies trader.

Pollock moved his operation to Louisiana, where he amassed even more wealth as a trader, and as a plantation owner. His success enabled him to provide supplies to the Patriots’ cause in the Revolutionary War, and to maintain close contact and a degree of influence with Congress. Pollock’s success allowed him easily to purchase military supplies to support "the cause," as the Spanish Empire had an outpost in New Orleans, Louisiana. In his dealings with the Spaniards, Pollock used their currency, the peso.

In true Spanish tradition, Pollock used an abbreviation for pesos, yet his penmanship made the abbreviation appear to be the transposition of the letters "p" and "s."

Prior to 1775, the fledgling nations monetary system was in disarray, and needed to be revamped. By 1775, Congress decided to rectify the situation by backing all of its legal tender with the most commonly circulated coins that were, coincidentally, Spanish coins minted in the New World. Americans then began trading with "Spanish milled dollars," later termed "dollars," as Americans shed the "pounds" that were the vestiges of British rule.

Congressman Robert Morris, to whom Pollock addressed his billing records, perpetuated the use of the dollar sign, and was the first high government official to give his blessing to the "s" with the two lines through it.

The appearance of the dollar sign in print, in a 1797 book by Chauncey Lee, signified the acceptance of the dollar as a purely American symbol, much as is the bald eagle. And, no, the dollar sign formed by placing the letter "U" over the letter "S" is not an abbreviation for Uncle Sam, as some have suggested!

Answer 4

Originally it was a "U" superimposed on an "S" (for US). Later the "U" was simplified to two vertical lines ("II") over the "S"; and later still, to one vertical line over the "S". But it comes from "US."
