Numismatics is the study or collection of currency, including coins, tokens, paper money, medals, and related objects. Experts of this study, 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 pound sterling (symbol: £; ISO 4217 currency code: GBP) is the official currency of the United Kingdom, Jersey, Guernsey, the Isle of Man, British Antarctic Territory, South Georgia and the South Sandwich Islands, and Tristan da Cunha. Various banknotes are used within the United Kingdom. The Bank of England has a legal monopoly of banknote issuance in England and Wales, but not in Scotland and Northern Ireland, where three banks in Scotland and three in Northern Ireland, issue their own banknotes as provisioned by the Banking Act 2009. However, the law requires that the issuing banks in Scotland and Northern Ireland hold a sum of Bank of England banknotes (or gold) equivalent to the total value of notes issued.
Versions of the pound sterling issued by Crown Dependencies and other areas are regulated by their local governments and not by the Bank of England. Four British Overseas Territories (Gibraltar, Saint Helena, Ascension Island and the Falkland Islands) also have currencies called pounds which are at par with the pound sterling. (Full article...)

The British decimal two pence piece (2p) is a denomination of sterling coinage equalling 1⁄50 of a pound, or two pence. 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...)
