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.

A bullion coin (also known as a specie) is a coin struck from highly refined precious metal (bullion) and kept as a store of value or an investment rather than used in day-to-day commerce. A bullion coin is distinguished by its weight (or mass) and fineness on the coin. Unlike rounds, bullion coins are minted by government mints and have a legal tender face value. Bullion coins can have fineness ranging from 91.9% (22 karat) to 99.99% purity (24 karat).

For the VAT exemption purposes the United Kingdom defines investment coins more specifically as coins that have been minted after 1800, have a purity of not less than 900 thousandths and are, or have been, legal tender in their country of origin. Under United States law, "coins" that fail the last of these requirements are not coins at all, and must be advertised as "rounds" instead. (Full article...)

The British decimal two pence coin (often shortened to 2p in writing and speech) is a denomination of sterling coinage equalling 2100 of a pound. Since the coin's introduction on 15 February 1971, the year British currency was decimalised, its obverse has featured four profiles of Queen Elizabeth II. In 2008 the design on its reverse changed from the original depiction of a plume of ostrich feathers with a coronet to a segment of the Royal Shield.

The two pence coin was originally minted from bronze, but changed in 1992 to copper-plated steel. (Full article...)
