LONDON - From a moustache comb to dazzling stage costumes, personal items belonging to late Queen front man Freddie Mercury will go under the hammer in September allowing fans to purchase memorabilia once owned by one of the world's most famous rock stars.

The crown is said to be based on St. Edward's Crown, which will be featured in King Charles III's coronation next month. Unlike the authentic centerpiece of Britain's Crown Jewels, the headpiece worn by Mercury is only estimated to sell for 60,000 to 80,000 pounds ($75,000-100,000). (PHOTO / AP)

They will go on public display for the first time in a month-long summer exhibition at Sotheby's in London before they are sold in six separate auctions, each dedicated to a different aspect of the singer's life

Some 1,500 items, including handwritten lyrics, art and collectibles from Mercury's London home, Garden Lodge, have been looked after by his close friend Mary Austin since his death from AIDS-related pneumonia in 1991.

"For many years now, I have had the joy and privilege of living surrounded by all the wonderful things that Freddie sought out and so loved. But the years have passed, and the time has come for me to take the difficult decision to close this very special chapter in my life," Austin said in a statement.

"It was important to me to do this in a way that I felt Freddie would have loved, and there was nothing he loved more than an auction."

Among the items for sale are Mercury's crown and regal cloak, worn for the "God Save The Queen" finale during the singer's last tour with Queen in 1986, with an auction estimate of 60,000 - 80,000 pounds ($74,838–$99,784).

Handwritten manuscript working lyrics for "We Are The Champions" have an estimate of 200,000–300,000 pounds, while those for "Killer Queen" have a price tag of 50,000–70,000 pounds.
