In 1924, the US army sent four planes in what would be the first round-the-world flight. The planes: the Seattle, Boston, New Orleans and Chicago, took off from Seattle. All but the Boston, which had crashed into a mountain in Alaska, completed the trip 175 days after their initial takeoff. Could this 1924 double eagle have flown around the world in the cockpit of one of the planes?
In 1908, Congress mandated that the motto IN GOD WE TRUST once again take its place on the Double Eagle. This ruling overturned an earlier decision by President Theodore Roosevelt, who believed that the use of a diety's name on circulating coinage was an act blasphemy. The Motto portion of the Saint-Gaudens series continued through 1933 with a singe interruption in yearly production from 1917-1919. By far the rarest issue of this era is the final-year 1933, of which only a single example is currently legal to own. That coin fetched a record $7,590,020 at auction in 2002. Other key dates are the 1920-S, 1921, 1927-D, 1927-S, 1929, 1930-S, 1931, 1931-D and 1932, most examples of which were melted in the Mint after President Franklin Delano Roosevelt issued the Gold Recall Act in 1933. Semi key-date issues include the 1908-S, 1924-D, 1924-S, 1925-D, 1925-S, 1926-D and 1926-S.
