"The motto IN GOD WE TRUST was placed on United States coins largely because of the increased religious sentiment existing during the Civil War."
"Salmon P. Chase received many appeals from devout persons throughout the country, urging that the United States recognize the Deity on United States coins. From Treasury Department records, it appears that the first such appeal came in a letter dated November 13, 1861."
The Congress passed the Act of April 22, 1864. This legislation changed the composition of the one-cent coin and authorized the minting of the two-cent coin. The Mint Director was directed to develop the designs for these coins for final approval of the Secretary. IN GOD WE TRUST first appeared on the 1864 two-cent coin.
Another Act of Congress passed on March 3, 1865. It allowed the Mint Director, with the Secretary's approval, to place the motto on all gold and silver coins that "shall admit the inscription thereon." Under the Act, the motto was placed on the gold double-eagle coin, the gold eagle coin, and the gold half-eagle coin. It was also placed on the silver dollar coin, the half-dollar coin and the quarter-dollar coin, and on the nickel three-cent coin beginning in 1866. Later, Congress passed the Coinage Act of February 12, 1873. It also said that the Secretary "may cause the motto IN GOD WE TRUST to be inscribed on such coins as shall admit of such motto."
