| | British Coin decimalisation |
 | | Unlike the earlier coins, all of which were made from nickel-brass, the new coins were bimetallic with a central cupro-nickel inner disc bonded to an outer brass ring. |
 | | By 1990, a combination of inflation and the realisation that the cupro-nickel coins were unnecessarily large, led to the five pence coin being reduced in weight and size, from 24mm diameter to 18mm. |
 | | The ten pence coin followed in 1992, reduced down to a size similar to the old five pence but, to prevent fraudulent use of old five pence coins, particularly in cash machines, it was made slightly larger and heavier. |
