The pre-decimal threepence (3d), usually simply known as a threepence or threepenny bit, was a unit of currency equalling one eightieth of a pound sterling, or three pence sterling. It was used in the United Kingdom, and earlier in Great Britain and England.
Maundy Threepence have been issued for centuries (they are still being struck today for ceremonial purposes), and initially the circulating threepence were identical in design. Starting in 1927, they were made different - this new design featuring three oak sprigs was developed for the circulating coins, while the Maundy threepence continued with the traditional crowned numeral reverse.
The composition is 0.500 silver, with 0.0227 oz ASW (ounces of Absolute Silver Weight).
This type was only issued for King George V. A new reverse featuring a Tudor rose was introduced for King George IV. The coins remained in circulation until "Decimal Day", 15 February 1971, and ceased to be legal tender after 31 August 1971. Unlike some of the larger denominations, they were not re-denominated to a decimal value when the decimal Pound Sterling was introduced. |
