The Seated Liberty dollar was a dollar coin struck by the United States Mint from 1840 to 1873 and designed by its chief engraver, Christian Gobrecht. It was the last silver coin of that denomination to be struck before passage of the Coinage Act of 1873, which temporarily ended production of the silver dollar for American commerce. The coin's obverse is based on that of the Gobrecht dollar, which had been minted experimentally from 1836 to 1839. However, the soaring eagle used on the reverse of the Gobrecht dollar was not used; instead, the United States Mint (Mint) used a heraldic eagle, based on a design by late Mint Chief Engraver John Reich first utilized on coins in 1807. Seated Liberty dollars were initially struck only at the Philadelphia Mint; in 1846, production began at the New Orleans facility. In the late 1840s, the price of silver increased relative to gold because of an increase in supply of the latter caused by the California Gold Rush; this led to the hoarding, export, and melting of American silver coins. The Coinage Act of 1853 decreased the weight of all silver coins of five cents or higher, except for the dollar, but also required a supplemental payment from those wishing their bullion struck into dollar coins. As little silver was being presented to the US Mint at the time, production remained low. In the final years of the series, there was more silver produced in the US, and mintages increased. In 1866, "In God we trust" was added to the dollar following its introduction to United States coinage earlier in the decade. Seated Liberty dollar production was halted by the Coinage Act of 1873, which authorized the trade dollar for use in foreign commerce. Representatives of silver interests were unhappy when the metal's price dropped again in the mid-1870s; they advocated the resumption of the free coinage of silver into legal tender, and after the passage of the Bland–Allison Act in 1878, production resumed with the Morgan dollar. == Background == The Mint Act of 1792 made both gold and silver legal tender; specified weights of each was equal to a dollar. The United States Mint struck gold and silver only when depositors supplied metal, which was returned in the form of coin. The fluctuation of market prices for commodities meant that either precious metal would likely be overvalued in terms of the other, leading to hoarding and melting; in the decades after 1792, it was usually silver coins which met that fate. In 1806, President Thomas Jefferson officially ordered all silver dollar mintage halted, though production had not occurred since 1804. This was done in part to prevent the coins from being exported to foreign nations for melting, causing a strain on the fledgling Mint for little gain. Over the next quarter century, the silver coin usually struck for bullion depositors was the half dollar. In 1831, Mint Director Samuel Moore requested that President Andrew Jackson lift the restriction against dollar coin production; the president obliged in April of that year. Despite the approval to strike the coins, no silver dollars were minted until 1836. The Bureau of the Mint in the 1830s was undergoing a period of significant change, as new technologies were adopted. In 1828, the Mint, whose authorization had been subject to periodic renewal by Congress since its inception in 1792, was given permanent status. A new building to house the Philadelphia Mint was authorized by Congress, and opened in 1832. Congress adjusted the precious-metal content of US coins in 1834 and 1837, and was able to achieve a balance whereby US coins remained in circulation alongside those of foreign nations (mostly Spanish colonial pieces). In 1836, the first steam machinery was introduced at the Mint; previously coins had been struck by muscle power. Congress had in 1835 authorized branch mints at Dahlonega in Georgia, Charlotte in North Carolina, and at New Orleans in Louisiana. The Charlotte and Dahlonega mints only struck gold, catering to miners in the South who sought to deposit that metal, but the New Orleans facility would also strike silver coins, including the Seated Liberty dollar. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Seated Liberty dollar」の詳細全文を読む スポンサード リンク
