Chinese cash (currency unit)
Chinese cash was a currency denomination used in China in imperial times. It was the chief denomination until the introduction of the yuan in the late 19th century.
Etymology
The English word "cash", meaning "tangible currency", is an older word from Portuguese caixa or Middle French caisse. The term was first used on coins issued in Guangdong Province in 1900. It did not appear on paper money until later. The plural forms "cash" and "cashes" were both used. The Chinese character wen has several other meanings in modern Chinese.History
The wen was one of the chief units of currency in China and was used to denominate both coins and paper money. Other denominations were used, including various weights, based on the tael system, for sycee silver and gold ingots. Chinese currency started 3000-4500 years ago but no one is quite sure.Until the 19th century, coins denominated in wen were cast, the most common formation being the round-shaped copper coin with a square or circular hole in the centre. The hole enabled the coins to be strung together to create higher denominations, as was frequently done due to the coin's low value. The number of coins in a string of cash varied over time and place but was nominally 1000. A string of 1000 wén was supposed to be equal in value to one tael of pure silver. Each string of cash was divided in ten sections of 100. The person who strung the cash into a string took one, two, or three cash per hundred, depending on local custom, as payment for his effort. So, in fact, an ounce of silver could vary in exchange from 970 to 990 cash between two places fairly close together. In places in the North where there was a shortage of coinage a string of 500 exchanged for an ounce of silver. Paper money sometimes showed pictures of the appropriate number of 1 wén coins strung together.
In the 19th century, foreign coins began to circulate widely in China, particularly silver coins such as the Mexican peso. In 1889, Chinese currency began to be denominated in the yuan and its subdivisions. The cash or wén was retained in this system as yuan. Traditional style, cast 1 wén coins continued to be produced until the end of the Chinese Empire in 1911. The last coins denominated in cash were struck in the early years of the Republic of China in 1924.
The term is still used today in colloquial Cantonese, but written as 蚊 to represent Hong Kong dollars.
