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

The ruble or rouble (Russian: рубль, romanized: rublʹ, [ˈrublʲ] ⓘ; symbol: ₽; ISO code: RUB) is the official currency of Russia. Banknotes and coins are issued by the Central Bank of Russia, which is Russia's monetary authority independent of all other government bodies.
The ruble is the second-oldest currency in continuous use, after pound sterling, as well as the first decimal currency. The ruble was the currency of the Russian Empire and later the Soviet Union, where it was known as the Soviet ruble (code: SUR, 810). Following the dissolution of the Soviet Union in 1991, the Soviet ruble was replaced in Russia with the Russian ruble (code: RUR, 810) at par in the following year. The Russian ruble continued to be used in 11 post-Soviet states, forming a "ruble zone" until 1993. In 1998, the ruble was redenominated (code: RUB, 643) shortly before the 1998 financial crisis, at a rate of 1000 RUR = 1 RUB. (Full article...)

The British decimal fifty pence coin (often shortened to 50p in writing and speech) is a denomination of sterling coinage worth 1⁄2 of one pound. Its obverse has featured the profile of the current British monarch since the coin's introduction in 1969. As of November 2024[update], six different royal portraits have been used.
As of March 2013[update] 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...)
