Numismatics is the study or collection of currency, including coins, tokens, paper money, medals and related objects.

Specialists, known as numismatists, are often characterized as students or collectors of coins, but the discipline also includes the broader study of money and other means of payment used to resolve debts and exchange goods.

The earliest forms of money used by people are categorised by collectors as "odd and curious", but the use of other goods in barter exchange is excluded, even where used as a circulating currency (e.g., cigarettes or instant noodles in prison). As an example, the Kyrgyz people used horses as the principal currency unit, and gave small change in lambskins; the lambskins may be suitable for numismatic study, but the horses are not.[dubious ] Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

The yen (Japanese: えん, symbol: ¥; code: JPY) is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, after the United States dollar and the euro. It is also widely used as a third reserve currency after the US dollar and the euro.

The New Currency Act of 1871 introduced Japan's modern currency system, with the yen defined as 1.5 g (0.048 troy ounces) of gold, or 24.26 g (0.780 troy ounces) of silver, and divided decimally into 100 sen or 1,000 rin. The yen replaced the previous Tokugawa coinage as well as the various hansatsu paper currencies issued by feudal han (fiefs). The Bank of Japan was founded in 1882 and given a monopoly on controlling the money supply. (Full article...)

The back of an Italian florin coin
The Florentine florin was a gold coin (in Italian Fiorino d'oro) struck from 1252 to 1533 with no significant change in its design or metal content standard during that time. It had 54 grains (3.499 grams, 0.1125 troy ounces) of nominally pure or 'fine' gold with a purchasing power difficult to estimate (and variable) but ranging according to social grouping and perspective from approximately 140 to 1,000 modern US dollars. The name of the coin comes from the Giglio bottonato (it), the floral emblem of the city, which is represented at the head of the coin. (Full article...)

The percentages above represent the proportion of all trades involving a given currency, regardless of which side of the transaction it is on. For example, the US dollar is bought or sold in 88% of all currency trades, while the euro is bought or sold in 31% of all trades.
