Decimalisation in Great Britain took place over three years: 1968 – 1971. From February 1971, all but three of the pre-decimal coins were demonetised leaving the sixpence, and the 1 and 2 Shilling coins. The sixpence had an equivalent value of 2.5 new pence, and was demonetised in 1980. The other two continued to circulate as 5 and 10 Pence coins until 1990 and 1992 respectively when the new coins were reduced in size.
The Halfpenny, Penny and Two Pence as issued in 1971.
