The Prudential Cups trophy were awarded to the winners of the World Cup from 1975–1983 when Prudential plc was the primary sponsors.
The trophies' designs changed when the sponsors changed until the 1999 World Cup.
So the first three world cups had a similar trophy while 1987 (Reliance World Cup sponsored by Reliance Industries), 1992 (Benson and Hedges Cup, sponsored by Benson and Hedges) and 1996 (Wills World Cup, sponsored by Wills, an ITC brand) had different trophies because of different sponsors until the International Cricket Council decided to award its own trophy.

The current trophy was created for the 1999 championships and is the first permanent prize in the tournament's history.
The trophy was designed and produced in London by a team of craftsmen from Garrard & Co (the Crown Jewellers).
The whole process was completed over a period of two months time.
