The Seated Liberty Silver Dollar coin of 1840 to 1873 was the first regular issue coin of this denomination since 1803 (technically, the 1804 Dollar was struck in 1834 and restruck in the 1860s). The No Motto variety was issued between 1840 and 1866, the motto "In God We Trust" added on the reverse between 1866 and 1873 due to the Act of March 3, 1865. The Mint Act of Feb. 12, 1873 abolished the coin in favor of the Trade dollar, an act called the Crime of '73 by opponents of the legislation. (by Richard Giedroyc)
