Where Did Some of the World’s Currency Symbols Come From, Like the $ and £ ?
The Pound Sterling, £, Symbol
This sign is simply a capital letter L, written in an old-fashioned handwriting style and with one or two crossbars to show that it is being used as a symbol or abbreviation. The L stands for the Latin word libra, the name of a Roman unit of weight, which also gave rise to the abbreviation lb for a pound as a measure of weight, and to the French word livre. The original British pound was designed as one pound of pure silver.
The Dollar, $, Symbol
The current leading etymology holds that ‘$’ was originally derived from an abbreviation for pesos, meaning ‘weight’ in Spanish. In the middle 1700s the peso was traded in all regions under Spanish control, from Southern California to South America, and the sign was commonly contracted as ‘ps.’ Many historians believe that the dollar sign we know today was born from the bad handwriting of merchants who allowed the line ‘p’ to fall in front of the s.
There is however another camp of scholars who think that the dollar sign originated from a far more deliberate abbreviation of peso. Originally referred to as the ‘piece of eight,’ the peso came to represent the Bolivian eight-sol and Peruvian eight-real coins. From this the ‘S’ in the modern dollar sign was thought to represent the numeral ‘8′ with the bisecting line meaning that the ‘8 was cut in pieces.’
However we may never know the true origin of the dollar sign.
The Yen, ¥, Symbol
The yen was adopted as Japan’s official currency in May, 1871. Like many other countries, the roots of the currency lie in silver. The yen was originally designed to weigh approximately 24.26 grams of pure silver, or 1.5 grams of pure gold although today yen coins are made of aluminum.
The word “yen” is actually pronounced as “en” in Japanese. Yen translates to “round object,” describing the shape of coins used by other countries. The “Y” used in the yen symbol may have been adopted due to the propensity of foreigners to pronounce the word “en” with a “y” preceding it.
The symbol for the Japanese yen was probably invented by analogy with the pound and dollar symbols, as it is a capital Y with one or two bars across it.
