Don Bradman's match-worn baggy green tipped to be sold for $1 million at auction

One of Sir Don Bradman's match-worn baggy greens has gone to auction, with expectations the prized item could be sold for $1 million.

The cap was gifted by Bradman to a fellow, unnamed Test cricketer that he shared the field with late in his career and has been in that family's possession for the past 75 years.

The item has been authenticated and it's believed Bradman wore it during Australia's first Test series against India in 1947-48.

It will go to auction through Lloyds Auctions and bids will close on January 26.

The bidding will start at $1 but it's expected to attract plenty of global interest from private collectors, museums and cricket enthusiasts across the globe.

"This is a genuine piece of cricket history that Sir Donald Bradman personally gifted," Lloyds Auctions chief operations officer Lee Hames said.

"Its uninterrupted family ownership for 75 years and its direct link to 'The Don' make it one of the most important Bradman-related pieces to come to auction.

"Closing on Australia Day gives it special national resonance for collectors honouring our sporting heritage."

It's not the first of Bradman's caps to be sold and none of them have come close to the $1m mark, with a baggy green from the same India series selling for $479,700 last year.

The cap from his first season as a Test player went for $450,000 five years ago while the one from his farewell tour to England sold for $425,000.

Bradman remains one of the greatest players in Test cricket history, having amassed almost 7000 runs during his career at an astonishing average of 99.94 - one of the greatest statistics in sporting history that will likely never be surpassed.

He retired in 1948 and was knighted the following year. He died in 2001 at the age of 92.
