The Numismatics Portal

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. Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems. (Full article...)

The Celtic currency of Britain were the various items and coins used as currency between approximately 200 BC and AD 60. The earliest currency consisted of various forms of iron bars. Coins were first imported in large numbers in around 150 BC and domestic minting began around 100BC. Coin production was largely ended by the Roman conquest of Britain, first by the Claudian invasion of AD 43 and later by the Defeat of Boudica in AD 60 or 61. Cast coins may have been produced for a few more years around Hengistbury Head. Exact dating of coins often changes in the light of new research.
Coin use is usually divided into a core area which covers the home counties as well as parts of Oxfordshire, Northamptonshire and Cambridgeshire. This was surrounded by a periphery of coin using groups some of which, the Corieltauvi, Durotriges, Dobunni and Iceni, appear to have minted their own coinage. The coins in the core area are generally attributed to the Atrebates and Cantii in the areas south of the Thames and the Trinovantes and Catuvellauni to the north. (Full article...)

The British decimal fifty pence piece (50p) is a denomination of sterling coinage worth 1⁄2 of a pound, or fifty pence. Its obverse has featured the profile of the current British monarch since the coin's introduction in 1969. It was introduced as a decimal replacement for the ten shilling banknote, which was also valued at half of a pound. As of November 2024, six different royal portraits have been used.
As of March 2013 there were an estimated 920 million 50p coins in circulation. The coin has proved popular with coin collectors, leading to numerous differing designs for both commemorative and circulating coins. (Full article...)
