There is something mythical about the famous 'Baggy Green' that Australian test cricketers are given at the beginning of their Test careers.
In reality, it is just a bottle green cap that is rather unremarkable to look at, but, to an Australian cricketer, it is the be-all and end-all.
It is possibly their most valued bit of kit and something they hold very dear throughout their playing days and beyond.
While players often make little of giving away shirts and other forms of memorabilia, their baggy is something they would normally keep for themselves due to its immense sentimentality.
However, with the incredible wildfires tearing through Australia at the moment, legendary leg spinner Shane Warne decided to auction off his famous cap to raise funds for the relief efforts.

Warne played in 145 Tests for Australia, forming an integral part of what was one of the greatest teams in history, taking a staggering 708 wickets in the course of his career.
He is undoubtedly the greatest leg spinner of all time and with his global celebrity status growing, you would expect that his baggy - as old and battered as it is - would fetch a pretty penny.
The auction sparked a fierce bidding war, culminating in an eye-watering sum of A$ 1,007,500 (£525,000).
The successful bidder, The Commonwealth Bank of Australia, plan to take the famous cap on a nationwide tour to raise further funds for the wildfire cause.
Other world-famous athletes continue to pledge their support as well with Lewis Hamilton recently donating $500,000 towards the rescue and care of wildlife caught up in the harrowing blazes.
Meanwhile, Brighton goalkeeper Mat Ryan has committed to donating A$500 for every save made by a goalkeeper in the Premier League this weekend.
The global support from the sporting world has been incredible, but Warne deserves special credit for putting the need of so many over the sentimentality of his special cap.
Well played, Warney.
