British Fifty Pence coin

The British decimal fifty pence (50p) coin was issued in October 1969 in the run-up to decimalisation to replace the ten shilling note.

The coin is minted from an alloy of 75% copper and 25% nickel. Between 1969 and 1997 the coin weighed 13.50 grams and had a diameter of 30.0 millimetres. In 1997 the coin was reduced in size to weigh 8.00 grams and have a diameter of 27.3 millimetres. Note that the coin is not circular but an equilaterally curved heptagon (seven-sided) to aid identification -- the sides are not straight but are curved so that the centre of curvature is the opposite apex of the coin, allowing the coin to roll freely and have its diameter measured correctly in slot machines (see also: curve of constant width). This shape was also later used for the Twenty Pence piece.

This denomination has frequently been used for commemorative purposes, and consequently there are more design variations in this coin than in any other current British denomination.

The normal reverse of the coin, designed by Christopher Ironside, depicts the seated Britannia with a lion, with the numeral "50" beneath, and either NEW PENCE (1969-1981) or FIFTY PENCE (since 1982) above Britannia.

During the history of the coin, three different obverses have been used so far - between 1969 and 1984 the head of Queen Elizabeth II by Arnold Machin was used, between 1985 and 1997 the head by Raphael Maklouf was used, and since 1998 one by Ian Rank-Broadley has been used.
