It is one of America's treasures. The most valuable ounce of gold in the world, the celebrated, the fabled, the infamous 1933 double eagle, illegal to own and coveted all the more, it has been sought with passion by men of wealth and with steely persistence by the United States government for more than a half century—it shouldn't even exist but it does, and its astonishing, true adventures read like "a composite of The Lord of the Rings and The Maltese Falcon" (The New York Times). In 1905, at the height of the exuberant Gilded Age, President Theodore Roosevelt commissioned America's greatest sculptor, Augustus Saint-Gaudens—as he battled in vain for his life—to create what became America's most beautiful coin. In 1933 the hopes of America dimmed in the darkness of the Great Depression, and gold—the nation's lifeblood—hemorrhaged from the financial system. As the economy teetered on the brink of total collapse, Franklin Delano Roosevelt, in his first act as president, assumed wartime powers while the nation was at peace and in a "swift, staccato action" unprecedented in United States history recalled all gold and banned its private ownership. But the United States Mint continued, quite legally, to strike nearly a half million 1933 double eagles that were never issued and were deemed illegal to own. In 1937, along with countless millions of other gold coins, they were melted down into faceless gold bars and sent to Fort Knox. The government thought they had destroyed them all—but they were wrong. A few escaped, purloined in a crime—an inside job—that wasn't discovered until 1944. Then, the fugitive 1933 double eagles became the focus of a relentless Secret Service investigation spearheaded by the man who had put away Al Capone. All the coins that could be found were seized and destroyed. But one was beyond their reach, in a king's collection in Egypt, where it survived a world war, a revolution, and a coup, only to be lost again. In 1996, more than forty years later, in a dramatic sting operation set up by a Secret Service informant at the Waldorf-Astoria, an English and an American coin dealer were arrested with a 1933 double eagle which, after years of litigation, was sold in July 2002 to an anonymous buyer for more than $7.5 million in a record-shattering auction. But was it the only one? The lost one? Illegal Tender, revealing information available for the first time, tells a riveting tale of American history, liberally spiced with greed, intrigue, deception, and controversy as it follows the once secret odyssey of this fabulous golden object through the decades. With its cast of kings, presidents, government agents, shadowy dealers, and crooks, Illegal Tender will keep readers guessing about this incomparable disk of gold—the coin that shouldn't be and almost wasn't—until the very end.
