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.

Ten Dollar Bill (also referred to as The Dollar Bill) is a 1956 proto-pop art lithographic drawing by Roy Lichtenstein. Considered to be a combination of Americana art and cubism, the work is referred to as the beginning of Lichtenstein's work on pop art. Twenty-five editions of the lithograph were made by Lichtenstein, which were exhibited at several galleries. The piece is based on the design for the ten-dollar bill and has influenced several of Lichtenstein's later works. The picture has received generally favorable reception from critics, and is considered to be one of the best artistic portrayals of currency. (Full article...)

The Thailand one-satang coin is a currency unit equivalent to one-hundredth of a Thai baht. It is rare in circulation but used in banking transactions.

The first satang coin was issued from 1908 to 1937, and featured a hole through the middle. It was made of bronze and measured 22mm in diameter, weighing 4.6g. It bore the name of King Rama VI. A coin in the same design was minted in 1939 with name of King Rama VIII, and had a mintage of 24.4 million. In 1941 the design of the coin changed, although it was still bronze with a hole. The diameter changed to 20mm and the weight to 3.5g. (Full article...)

  1. ^ The total sum is 200% because each currency trade is counted twice: once for the currency being bought and once for the one being sold. 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.
