Post-1901 Farthings
Farthings weighing 2.7–2.9 grams and of 20 millimetres diameter (which was to remain the standard size of the coin for the remainder of its existence) were minted in all years of Edward VII's reign (1901–1910) except 1901. They are similar to the last issues of Queen Victoria except for the king's right-facing bust on the obverse, with the inscription, and also are extremely reminiscent of the contemporary penny and halfpenny. These farthings were issued in an artificially toned state so that they would not be confused with the half-sovereign coin. The last half-farthing coin was a "coronation model" of King Edward VII in 1902.
The reign of King George V produced farthings to a basically unchanged design every year between 1911 and 1936. The obverse shows a left-facing portrait of the king by Sir Bertram Mackennal, with the inscription, and the usual right-facing Britannia on the reverse. Unlike some of the pennies of this reign, no farthings have mintmarks from provincial mints. Until 1917, farthings were issued in an artificially toned state so that they would not be confused with the half-sovereign coin, but by the end of the war half-sovereigns were no longer being struck. The content of the bronze used in the farthing was changed in 1923 to 95.5% copper, 3% tin and 1.5% zinc, although the weight of the coin remained 2.8–2.9 grams and the diameter was 20 millimetres.
The Edward VIII farthing is a pattern which was awaiting royal approval at the time of the abdication in December 1936. The king insisted that his left profile be used on the coinage instead of the right which would have been used if he had followed the alternating tradition going back to Charles II; the obverse has the inscription, but in a complete break from tradition Britannia was dropped from the reverse for the first time since 1672, and replaced by one of Britain's smallest birds, the wren. This reverse remained in use for the remainder of the coins' existence.
Farthings of a similar design to his brother's were produced in each year of the reign of King George VI. The inscription on the obverse reads until 1948, then, but unlike the halfpenny there were no minute differences in the reverse each year.
The farthing of Queen Elizabeth II was only produced in four years, 1953–1956. The reverse was the same as before, while the obverse featured the queen's head by Mary Gillick, with the inscription in 1953, and for the other three years.
