£sd
Summary
£sd (occasionally written Lsd), spoken as "pounds, shillings and pence", is the popular name for the pre-decimal currencies once common throughout Europe. The abbreviation originates from the Latin currency denominations librae, solidi, and denarii. In the United Kingdom, these were referred to as pounds, shillings, and pence (pence being the plural of penny).
Under this system, there were 12 pence in a shilling and 20 shillings, or 240 pence, in a pound. Although the standard ledger accounting system recorded only pounds, shillings and pence, actual minted coins could represent one, several or fractions of these units. The penny was subdivided into 4 farthings until 31 December 1960, when they ceased to be legal tender in the UK, and until 31 July 1969 there was also a halfpenny ("HAYp'ny", /ˈheɪpni/) in circulation. The perceived advantage of such a system was its use in some aspects of mental arithmetic, as it afforded many factors and hence fractions of a pound such as tenths, eighths, sixths and even sevenths and ninths if the guinea (worth 21 shillings) was used. When dealing with items in dozens, multiplication and division are straightforward; for example, if a dozen eggs cost four shillings, then each egg was priced at fourpence. Basic addition, however, could be more difficult than using a decimal system.
Although the names originated from popular coins in the classical Roman Empire, their definitions and the ratios between them were introduced and imposed across Western Europe by the Emperor Charlemagne. King Offa of Mercia adopted the Frankish silver standard of librae, solidi and denarii into Britain in the late 8th century.
The £sd system was the standard across much of the European continent for over a thousand years, until the decimalisations of the 18th and 19th centuries. The United Kingdom remained one of the few countries retaining it into the 20th century, resulting in the system becoming particularly associated with Britain. For much of the 20th century, £sd remained the monetary system of most of the British Commonwealth, the major exceptions being Canada and India, until the 1960s and 1970s, with Nigeria being the last to abandon it in the form of the Nigerian pound on 1 January 1973.
Historically, similar systems based on Roman coinage were used elsewhere; e.g., the division of the livre tournois in France and other pre-decimal currencies such as Spain, which had 20 maravedís to 1 real and 20 reales to 1 duro or 5 pesetas.
