The U.S. Congress authorized the creation of a two-cent coin (pictured), the first U.S. currency to bear the phrase "In God We Trust".
Coinage Act of 1864
The Coinage Act of 1864 was a United States federal law passed on April 22, 1864, which changed the composition of the one-cent coin and authorized the minting of the two-cent coin. The Director of the U.S. Mint developed the designs for these coins for final approval of the Secretary of the Treasury. As a result of this law, the phrase "In God We Trust" first appeared, on the 1864 two-cent coin. An Act of Congress, passed on March 3, 1865, allowed the Mint Director, with the Secretary's approval, to place the phrase on all gold and silver coins that "shall admit the inscription thereon." In 1956, "In God We Trust" replaced "E Pluribus Unum" as the national motto. Beginning in 1957 currency was also printed with the motto. The law also made it illegal to privately mint one and two cent coins for circulation, thus effectively ending the production of Civil War tokens.
Two-cent piece (United States)
The two-cent piece was produced by the Mint of the United States for circulation from 1864 to 1872 and for collectors in 1873. Designed by James B. Longacre, there were decreasing mintages each year, as other minor coins such as the nickel proved more popular. It was abolished by the Mint Act of 1873.
In God We Trust
"In God We Trust" is the official motto of the United States as well as the motto of the U.S. state of Florida, along with the nation of Nicaragua. It was adopted by the U.S. Congress in 1956, replacing E pluribus unum, which had been the de facto motto since the initial design of the Great Seal of the United States.
