Threepence (British coin)
The British threepence piece, usually simply known as a threepence, thruppence, or thruppenny bit, was a denomination of sterling coinage worth 1⁄80 of one pound or 1⁄4 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.
