Money was historically an emergent market phenomenon that possessed intrinsic value as a commodity; nearly all contemporary money systems are based on unbacked fiat money without use value. Its value is consequently derived by social convention, having been declared by a government or regulatory entity to be legal tender; that is, it must be accepted as a form of payment within the boundaries of the country, for "all debts, public and private", in the case of the United States dollar.
The British farthing (derived from the Old Englishfeorthing, a fourth part) was a British coin worth a quarter of an old penny (1⁄960 of a pound sterling). It ceased to be struck after 1956 and was demonetised from 1 January 1961.
The British farthing is a continuation of the English farthing, struck by English monarchs prior to the Act of Union 1707 which unified the crowns of England and Scotland into the Kingdom of Great Britain. Only pattern farthings were struck under Queen Anne as there was a glut of farthings from previous reigns. The coin was struck intermittently under George I and George II, but by the reign of George III, counterfeits were so prevalent the Royal Mint ceased striking copper coinage after 1775. The next farthings were the first struck by steam power, in 1799 by Matthew Boulton at his Soho Mint under licence. Boulton coined more in 1806, and the Royal Mint resumed production in 1821. The farthing was struck fairly regularly under George IV and William IV. By then it carried a scaled-down version of the penny's design, and would continue to mirror the penny and halfpenny until after 1936. (Full article...)
The europa was a token coinage created in 1928 by Joseph Archer [fr], a politician and industrialist from the Nièvre region in France. The currency was promoted by Philibert Besson [fr], the elected deputy for the Haute-Loire who, along with Archer, was an influential figure in the European federalist movement. The coins were minted in the name of a hypothetical "Federated States of Europe" (États fédérés d'Europe). Unlike contemporary currencies based on the gold standard, the europa was intended to derive its notional value from its value in labour.
The currency never circulated except unofficially between federalists of the Nièvre region. Two denominations were produced, both depicting Louis Pasteur and a map of Europe on the obverse and reverse respectively: one valued at 1 europa and another at 1/10 of a europa. (Full article...)
