The coin in DimesWorth's logo is the Winged Liberty Head dime, designed by Adolph Alexander Weinman, issued between 1916 and 1945. This coin is more commonly known as the 'Mercury' dime. Why? The wings on the cap worn by Lady Liberty led to a case of mistaken identity - for the Roman messenger god. In fact, the design was meant to suggest freedom of thought, not the fleetness of foot. But Mercury is also responsible for commerce, so maybe the designation is appropriate after all. Given the speed of business these days, the traditional concept of Mercury isn't so far off the mark either.

Misnomer or not, the nickname has sent the coin into space. In 1961, astronaut Gus Grissom carried seven "Mercury" dimes on board the 'Liberty Bell 7' for luck. This Mercury mission was successful, but it's questionable whether or not the dimes did their work, since the Liberty Bell 7 sank shortly after splashdown. When the capsule was recovered from the ocean floor by the Discovery Channel expedition in July 1999, the dimes were still on board. In spite of their nearly four-decades-long soak, the dimes were more fortunate than Grissom, who died in the Apollo I capsule fire in 1967.
