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." //

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." //

The motto has been in continuous use on the one-cent coin since 1909, and on the ten-cent coin since 1916. It also has appeared on all gold coins and silver dollar coins, half-dollar coins, and quarter-dollar coins struck since July 1, 1908. //

A law passed by the 84th Congress (P.L. 84-140) and approved by the President on July 30, 1956, the President approved a Joint Resolution of the 84th Congress, declaring IN GOD WE TRUST the national motto of the United States. IN GOD WE TRUST was first used on paper money in 1957, when it appeared on the one-dollar silver certificate. The first paper currency bearing the motto entered circulation on October 1, 1957.
