context_page_description: Cash was a type of coin of China and East Asia, used from the 4th century BC until the 20th century AD, characterised by their round outer shape and a square center hole. Originally cast during the Warring States period, these coins continued to be used for the entirety of Imperial China as well as under Mongol and Manchu rule. The last Chinese cash coins were cast in the first year of the Republic of China. Generally most cash coins were made from copper or bronze alloys, with iron, lead, and zinc coins occasionally used less often throughout Chinese history. Rare silver and gold cash coins were also produced. During most of their production, cash coins were cast, but during the late Qing dynasty, machine-struck cash coins began to be made. As the cash coins produced over Chinese history were similar, thousand year old cash coins produced during the Northern Song dynasty continued to circulate as valid currency well into the early twentieth century.
  In the modern era, these coins are considered to be Chinese “good luck coins”; they are hung on strings and round the necks of children, or over the beds of sick people.
context_section_description: During the late Qing dynasty under the reign of the Guangxu Emperor in the mid 19th century the first machine-struck cash coins were produced, from 1889 a machine operated mint in Guangzhou, Guangdong province opened where the majority of the machine-struck cash would be produced. Machine-made cash coins tend to be made from brass rather than from more pure copper as cast coins often were, and later the copper content of the alloy decreased while cheaper metals like lead and tin were used in larger quantities giving the coins a yellowish tint. Another effect of the contemporary copper shortages was that the Qing government started importing Korean 5 fun coins and overstruck them with "10 cash".
  The production of machine-struck cash coins in Qing China ran contemporary with the production of machine-struck French Indochinese Nguyễn cash coins, but unlike in China milled cash coinage would eventually become popular in French Indochina with the Khải Định Thông Bảo (啓定通寶) .
