By the end of the 17th century, the Chinese economy had recovered from the devastation caused by the wars in which the Ming dynasty were overthrown, and the resulting breakdown of order. In the following century, markets continued to expand as in the late Ming period, but with more trade between regions, a greater dependence on overseas markets and a greatly increased population. After the re-opening of the southeast coast, which had been closed in the late 17th century, foreign trade was quickly re-established, and was expanding at 4% per annum throughout the latter part of the 18th century. China continued to export tea, silk and manufactures, creating a large, favorable trade balance with the West. The resulting inflow of silver expanded the money supply, facilitating the growth of competitive and stable markets.
What did the Chinese get paid for their goods?
silver

The colloquialism "buck"(s) (much like the British word "quid"(s, pl) for the pound sterling) is often used to refer to dollars of various nations, including the U.S. dollar. This term, dating to the 18th century, may have originated with the colonial leather trade. It may also have originated from a poker term. "Greenback" is another nickname originally applied specifically to the 19th century Demand Note dollars created by Abraham Lincoln to finance the costs of the Civil War for the North. The original note was printed in black and green on the back side. It is still used to refer to the U.S. dollar (but not to the dollars of other countries). Other well-known names of the dollar as a whole in denominations include "greenmail", "green" and "dead presidents" (the last because deceased presidents are pictured on most bills).
What is the British equivalent of a "buck"?
quid
