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 – discuss] Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

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 the 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...)Money - Coins - Banknotes - Electronic money - Exchange rate - Legal tender - Clubs - Terminology
