Overview
The British threepence piece, usually simply known as a threepence, thruppence, or thruppenny bit, was a denomination of sterling coinage worth of one pound or of one shilling. It was used in the United Kingdom, and earlier in Great Britain and England. Similar denominations were later used throughout the British Empire and Commonwealth countries, notably in Australia, New Zealand and South Africa.
The sum of three pence was pronounced variously , or , reflecting different pronunciations in the various regions of the United Kingdom. The coin was often referred to in conversation as a , or bit. Before Decimal Day in 1971, sterling used the Carolingian monetary system, under which the largest unit was a pound divided into 20 shillings, each of 12 pence. The threepence coin was withdrawn in 1971 due to decimalisation and replaced by the decimal new penny, with 2.4d being worth 1p.
Early threepences
The three pence coin – expressed in writing as "3d" – first appeared in England during the fine silver coinage of King Edward VI (1547–53), when it formed part of a set of new denominations. Although it was an easy denomination to work with in the context of the old sterling coinage system, being a quarter of a shilling, initially it was not popular with the public who preferred the groat (four pence). Hence the coin was not minted in the following two reigns – if one controversially counts Jane or incorrectly treats coins in the sole name of Mary as being a separate "reign" from those which also show and name her husband Philip.
