The penny was not the smallest unit of currency. Until 1960, this title was held by the farthing (one quarter of a penny). After 1960, the smallest unit was the halfpenny (known as the ha'penny, pronounced ''haip-nee''). After decimalisation, a half-penny coin was circulated until 1984. | The penny was not the smallest unit of currency. Until 1960, this title was held by the farthing (one quarter of a penny).
