The Dynasty icon cleared out her closets and vast collection of memorabilia for the Julien's Auctions sale last week (ends18Dec15), and among the highlights was the custom dress and matching caplet she wore for her royal investiture ceremony in March (15).

The lot had been expected to fetch at least $5,000 (£3,333), but it was snapped up for an impressive $20,025 (£13,350).

Another big draw was a metal cast of Marilyn Monroe's hand and footprints for the Grauman's Chinese Theatre in Hollywood, which had a final bid of $45,025 (£30,017). The late blonde bombshell's conversion to Judaism certificate also went under the hammer, selling for $68,750 (£45,833).

Meanwhile, two love letters Collins received from former lover Warren Beatty went for $1,920 (£1,280), and a manual 1973 British MG roadster the veteran actress never learned to drive sold for $8,525 (£5,683).

However, there was one item Collins had to withdraw from the Beverly Hills auction - a beaded Versace jacket she couldn't bear to part with.

"She took it back because it was too fabulous," a longtime friend tells the New York Post.

Collins had also previously admitted she was having second thoughts about selling off a statement gold Versace necklace.

"This necklace, this is a Versace necklace and I've worn this several times," she confessed. "I think it's rather fabulous, it's very dramatic and, yes, I was thinking 'maybe I will buy it back'."

It is not known if the star did indeed repurchase the item.
