Magpies years ago, on February, 15th, 1971 Britain has changed the monetary system.
Old money consisted of pound, as well as now, but each pound was divided into 20 shillings, each shilling, has been divided into 12 pence, or a penny.
At that time there was difficult enough set of coins. The small coin was called a farthing. It equaled penny quarters, and on one party there was a pattern - a birdie-korolek. Certainly, the farthing cost very little, and has ceased to be used in 1960. Then there was half of penny, or ha'penny as it then named. There was a coin in one penny, and a strange coin in three pence - not round, and with 12 direct parties. It was called "thru'penny bit". There were small silver coins in 6 pence, coins in two shillings which were called as "florins", and coins in nominal value two shillings and six pence, carried the name - "half of crown". Then there was a note in 10 shillings, and also notes in one pound, and larger nominal values.
People who visited Great Britain have been very puzzled by this old money. Everywhere in the world monetary units (for example, the US dollar or franc France or DM), were divided into 100 smaller units (for example cents, centimes, or pfennigs). To the middle of 1960th years, the government of Great Britain has decided that should were make the same. To multiply and divide on 12 and on 20 it was too difficult. The United Kingdom should get to conformity with other world, and decimal currency (that is currency with parts 10, 100 etc.).
Thus, the government of Britain, it has been nominated on February, 15th, 1971, as day D, or "decimal day" when all country will start to use new currency - pound which is divided into 100 pence. A royal mint (the governmental department responsible for a conclusion in circulation of coins and notes) has manufactured new brilliant coins, and within several months old and new money together was used.
After British have changed old money, it was natural to think of change of other things, such as units of measure and distances. By degrees, within the last 30 years, Great Britain has passed to kg and metre use, partly because the European community wants the general system in all European countries. However, in Britain it is still authorised to use some old units of measure. And if you go to the British pub reserve a pint, instead of beer half-litre.
