An 18th-century scribal evolution from "p̃s" (pesos) abbreviation
Before American independence in the 1700s, the primary currency for trade in North America was not the British pound, but the Mexican and Spanish peso, commonly known as the "Spanish dollar." Silver coins, mined from Mexican silver mines, circulated widely throughout the 13 North American colonies, traveling via the Caribbean. It was standard practice to record 'peso' in accounting ledgers throughout the region, reflecting its widespread acceptance.
Accounting scribes often abbreviated "peso" as "p̃s" (a 'p' with a tilde and a superscript 's'). Through repeated, rapid handwriting, the rounded curve of the 'p' gradually disappeared, leaving only its vertical stroke, while the 's' became superimposed over it. By the late 1770s, receipts show a symbol almost identical to the modern '$' sign. This evolution was not the creation of a single individual, but rather the condensed result of countless accountants' handwriting over several decades.
After American independence, a new national currency needed to be established. Thomas Jefferson proposed a decimal currency system instead of the British pound, where 1 dollar would equal 100 cents. Congress adopted this proposal in 1785. At this time, the '$' symbol, already well-established in accounting ledgers, was simply adopted. Thus, the symbol for the U.S. dollar was not created by the United States itself, but is a direct legacy of the Spanish peso.
The Chinese character '幣' (bì, 'pye' in Korean) is composed of '巾' (jīn, cloth) and '敝' (bì, worn out), signifying 'a guarantee of value made from old cloth.' Characters like '貨幣' (huòbì, currency), '通幣' (tōngbì, circulating currency), and '紙幣' (zhǐbì, paper money) all share this same character. The fundamental nature of currency is a 'promise agreed upon by society as valuable.' Whether it's a peso or a dollar, paper or digital, only the form of this promise changes. One symbol has thus traversed through eras of colonialism, independence, and globalization.
