From RugbyRugby.com: "With no way of determining exactly which ball was slotted through the middle of the uprights by England fly-half Jonny Wilkinson to win the Rugby World Cup, English newspaper The Sun, did the next best thing - they bought all four!
The Sun launched a campaign earlier in December for the return of the match-winning ball, demanding that the Australians return to England what was rightfully theirs, but there was no way of telling what happened to the ball.
It was later discovered that all four match balls were auctioned off ahead of the game and won by four Australians, although which ball was destined to become a piece of history is anybody's guess."
