The threepence or threepenny bit was a denomination of currency used by various jurisdictions in England, Ireland, Scotland and Wales, valued at 1/80 of a pound or of a shilling until decimalisation of the pound sterling and Irish pound in 1971. It was also used in some parts of the British Empire (later known as the Commonwealth), notably Australia, New Zealand and South Africa. Before decimalisation brought about a new currency with new coinage, the sum of three pence was pronounced variously , , , reflecting different pronunciations in the various regions and nations of Great Britain. Likewise, the coin was usually referred to in conversation as a , , bit. Early threepences The three pence coin – expressed in writing as "3d" – first appeared in England during the fine silver coinage of King Edward VI (1547–1553), 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. Edward VI threepences were struck at the London and York mints. The obverse shows a front-facing bust of the king, with a rose to the left and the value numeral III to the right, surrounded by the legend . The reverse shows a long cross over the royal shield, surrounded by the legend (London mint) (I have made God my helper), or (York mint) (City of York). Queen Elizabeth I (1558–1603) produced threepences during her third coinage (1561–1577). Most 1561 issues are 21 mm in diameter, while later ones are 19 mm in diameter. These coins are identifiable from other denominations by the rose behind the queen's head on the obverse, and the date on the reverse. The obverse shows a left-facing crowned bust of the queen with a rose behind her, surrounded by the legend , while the reverse shows shield over a long cross, dated 1561, surrounded by the legend . Dates used for the smaller coins were 1561–77. Threepences of the fourth coinage (1578–1582) are identical except for having a slightly lower silver content. There was also a fairly rare milled coinage threepence, produced between 1561 and 1564 with similar designs and inscriptions to the hammered coinage threepences. The threepence
