British old money to decimal currency

The need for a decimal currency system had been discussed in Parliament in the early nineteenth century and as far back as 1849 a florin was introduced - inscribed one tenth of a pound with the intention that it should be the first step towards the adoption of a decimal system.

Over a century later, on the 1 March 1966, the Chancellor of the Exchequer, James Callaghan announced that the old £sd system would be replaced by a decimal currency in which the pound was to be divided into one hundred units. Although fiercely challenged the change was confirmed by the Decimal Currency Act of 1967.
