History of the British penny (1714–1901)

The penny of Great Britain and the United Kingdom from 1714 to 1901, the period in which the House of Hanover reigned, saw the transformation of the penny from a little-used small silver coin to the bronze piece recognisable to modern-day Britons. All bear the portrait of the monarch on the obverse; copper and bronze pennies have a depiction of Britannia, the female personification of Britain, on the reverse.
