The British penny ( of a pound sterling), a large, pre-decimal coin which continued the series of pennies which began in about the year 700, was struck intermittently during the 20th century until its withdrawal from circulation after 1970. From 1901 to 1970, the obverse ("heads" side) of the bronze coin depicted the monarch who was reigning at the start of the year. The reverse, which featured an image of Britannia seated with shield, trident, and helm, was created by Leonard Charles Wyon based on an earlier design by his father, William Wyon. The coins were also used in British colonies and dominions that had not issued their own coins.
