Description
The 1940 (S) Mercury Dime is a dime produced at the San Francisco Mint as part of the Mercury Dimes 1916-1945 series. The U.S. Mint produced 21.6 million examples, making this ranked 2nd of 3 mint variants by mintage, with 20% of production. The obverse features young Liberty wearing a winged Phrygian cap, symbolizing freedom of thought — often called the "Mercury" dime despite not depicting the Roman god and the reverse displays a Roman fasces — a bundle of rods with an axe — entwined with an olive branch, symbolizing strength through unity tempered by peace. Struck during the Great Depression, when mintages dropped sharply and the United States abandoned the gold standard in 1933. Struck at the San Francisco Mint, established during the California Gold Rush and now primarily producing proof and collector coins. Estimated market value ranges from $7 to $47 depending on grade and condition. Struck in 90% silver, 10% copper, weighing 2.5 grams, 17.9 mm in diameter, with a reeded edge. Cataloged as PCGS #5026.
