<P> Beginning with Lord Wrottesley 's proposals in the 1820s , there were various attempts to decimalise the pound sterling over the next century and a half . These attempts came to nothing significant until the 1960s when the need for a currency more suited to simple monetary calculations became pressing . The decision to decimalise was announced in 1966 , with the pound to be divided into 100 , rather than 240 , pence . Decimal Day was set for 15 February 1971 , and a whole range of new coins were introduced . Sixpences continued to be legal tender with a value of ​ 2 ⁄ new pence until 30 June 1980 . </P>
