(CNN) -- Britain's Chris Froome won the 17th stage of the Tour de France on Wednesday to strengthen his grip on the yellow jersey. Froome completed Wednesday's 32-kilometer time trial in 51 minutes 33 seconds, nine seconds ahead of Spain's Alberto Contador with his compatriot Joaquim Rodriguez Oliver finishing a further second behind in third. "I couldn't believe it when I got over the line and saw I had the fastest time," Froome said after his third stage win of this year's tour. "I went into today thinking I was going to try and limit my losses, thinking about the days to come now. So to go through the finish line with the fastest time, I really didn't see that coming." On mountainous terrain along a frequently twisting route most of the riders opted for their traditional road bikes over the more aerodynamic machines used in time trials. But Froome opted to use both on the stage, switching to a time trial model for the final 12-kilometer descent. The swap proved decisive as the Briton clawed back a 20-second advantage Contador had built up earlier in the stage. The Spaniard now moves up to second overall, four minutes 34 seconds behind Froome with just four stages remaining. Contador's Saxo-Tinkoff teammate Roman Kreuziger is now third and trails Froome by four minutes and 51 seconds. Thursday sees the riders tackle the gruelling 172.5-kilometer 18th stage which concludes with a double ascent of Alpe d'Huez over the last 60 kilometers. <sep>How long did Fromme bike on the 17th stage before the final descent?<sep>32 kilometers

The 1933 double eagle, a $20 gold piece with a mysterious history that involves a president, a king and a Secret Service sting operation, was auctioned Tuesday last night for a record price for a coin, $7.59 million, nearly double the previous record. The anonymous buyer, believed to be an individual collector who lives in the United States, made the winning bid in a fiercely contested nine-minute auction at Sotheby's in Manhattan. Eight bidders were joined by 500 coin collectors and dealers in an auction house audience seemingly devoid of celebrity bidders, while an additional 534 observers followed the bidding on eBay. As auction houses prepare for their fall seasons in an uncertain economy, the sale price "suggests that the marketplace for important items is enormously strong," said David Redden, a vice chairman at Sotheby's, who was the auctioneer. "This is an astonishing new record for a coin," he said. In an unprecedented move, the auction proceeds were split by the U.S. Mint and a London coin dealer, Stephen Fenton, who had won that right in court after having been arrested by Secret Service agents for trying to sell the coin in the Waldorf-Astoria Hotel in Manhattan in 1996. Henrietta Holsman Fore, the director of the U.S. Mint, who witnessed the sale, said, "The monies we receive will go toward helping to pay down the debt and to fight the war on terrorism." Fenton commented that the double eagle had been on "a long historic journey, with a very satisfying ending." He added, "I am thrilled with the price." The previous numismatic record holder was an 1804 U.S. silver dollar, which sold for $4.14 million in 1999. Sotheby's partner in the one-lot auction was Stack's Rare Coins, with which it shared the customary 15 percent commission. "I have never seen as much interest in the sale of any coin in my 30 years in the business," said Lawrence R. Stack, the company's managing director. "This is the Mona Lisa of coins," said Beth Deisher, editor of Coin World, the largest weekly coin publication in the United States, with a circulation of 85,000. "It is unique. Forbidden fruit." Collectors' Web sites have surged with speculation about the sale price, and enthusiasts even organized betting pools. <sep>Who stated, "This is an astonishing new record for a coin?"<sep>Collector's Web
