Farthings first came into production during the reign of Charles II in 1672 due to a considerable shortage of coins of low denomination. It is always a sign that coins of a certain denomination are needed when tradesmen issue private tokens bearing that denomination, and the well-known tokens of 1660 are a clear indication of the need for the coin.
An extensive series of pattern farthings was struck from the beginning of the reign, but it was not until 1672 that farthings were struck for circulation. The Royal Proclamation of 1672 authorised the striking of farthings and half pennies with legal tender status up to a total of sixpence, but the issue of half pennies was delayed. The Farthing thus became the first of the long series of base metal ‘Britannia’ coinage which was to last almost exactly 300 years.
Like the half penny,the design of the Farthing would also change during George VI’s reign. The design adopted for the reverse was that of a wren, which had been proposed for the reverse of the Edward VIII Farthing. The coin was struck for every year of the reign but, unlike the half penny, it did not undergo minute differences of design from year to year.
