The whole radiated., This prestigious coin was struck at the Carson City Mint, established during the silver rush in 1863, opened in 1870, and closed in 1893. It shows signs of heavy circulation but remains visually appealing. While the California Gold Rush began around 1848, the Silver Rush began in Nevada and Utah in 1859 with the discovery of massive silver lodes. The first mine, Comstock Lode, was discovered that same year and established in 1862. The following year, the Carson City Mint opened and was initially intended to mint the silver extracted from these mines. Carson City also minted some gold coins from the outset using metal from the Carlin Trend mine and other mines in northeastern Nevada. Of the three subtypes of the “Liberty Head $20” type, Carson City only minted the last two. The first type, minted between 1849 and 1866, does not feature the U.S. motto. The second type, to which our coin belongs, features the motto and an abbreviated denomination and was minted between 1866 and 1876. The last type, minted between 1877 and 1907, features the denomination written out in full. Over the twenty years that the Carson City Mint was in operation, 1874 was the second-most significant year in terms of the number of coins minted of this type and subtype; the first being 1876. Nevertheless, California’s monopoly on gold remains evident in the number of coins minted. San Francisco minted no fewer than 1,214,000 coins (see PCGS), which is 3.3 times more than Philadelphia (366,780 coins according to PCGS) and 10.5 times more than Carson City, which minted 115,085 coins (see PCGS). These numbers thus demonstrates the rarity of both this type and this mint, while also bearing witness to the history of Nevada and the United States in the second half of the 19th century., UNITED STATES OF AMERICA / TWENTY D.
