This June 7 Bonham’s will auction off the 1928 Rolls-Royce 40/50hp Phantom I Ascot Dual Cowl Sport Phaeton with coachwork by Brewster that starred in the 1974 movie version of The Great Gatsby.

The sale will take place during the Greenwich Concours d’Elegance in Connecticut and the car is expected to fetch anywhere between $150,000 and $200,000.

The car belongs to Massachusetts collector Ted Leonard, who leant it for the film.

A flawless blue diamond weighing 7.03 carats has sold for a record 10.5 million Swiss francs ($9.49 million), the highest price paid per carat for any gemstone at auction, Sotheby’s said.

A Georgia man’s collection of more than 10,000 Abraham Lincoln stamps has sold at auction in New York City for a total of nearly $2 million.

The collection was amassed by William Ainsworth, a retired executive from the consulting and accounting firm KPMG.
