What is a farthing?
The British farthing coin, from "fourthing," was a unit of currency of one quarter of a penny, or one nine hundred and sixtieth of a pound sterling. It was minted in bronze, and replaced the earlier copper farthings. It was used during the reign of six monarchs: Victoria, Edward VII, George V, Edward VIII, George VI and Elizabeth II, ceasing to be legal tender in 1960. It featured two different designs on its reverse during its one hundred years in circulation. From 1860 until 1936 the image of Britannia, and from 1937 onwards the image of a wren. Like all British coinage, it bore the portrait of the monarch on the obverse.
Before Decimal Day in 1971 there were two hundred and forty pence in one pound sterling. There were four farthings in a penny. Twelve pence made a shilling, and twenty shillings made a pound. Values less than a pound were usually written in terms of shillings and pence. Values of less than a shilling were simply written in terms of pence. A price with a farthing in it would be written like this: (19/11¼), pronounced "nineteen and elevenpence farthing".
