The Civil War emptied the country of federal coins. People hoarded silver and gold, and by 1862 even the copper-nickel cent had vanished, leaving shopkeepers to make change with private tokens, many of them thin bronze pieces worth far less than a cent. Mint Director James Pollock noticed that those tokens circulated freely, and late in 1863 he proposed a bronze cent and a bronze two-cent piece. A two-cent coin let the Mint put more face value into circulation for the same press time.
The Coinage Act of 1864, signed by President Abraham Lincoln on April 22, 1864, authorized both coins in French bronze. It was also the first law to make base-metal coins legal tender, up to ten pieces at a time.
The new coin carried a new motto. In 1861 the Reverend Mark R. Watkinson had asked Treasury Secretary Salmon P. Chase to recognize God on the coinage, and Chase told the Mint to prepare a suitable motto. Pollock's patterns tried "God Our Trust", and Chase asked that the shield design read IN GOD WE TRUST instead. The 1864 act let the Mint Director, with the Secretary's approval, set the mottoes, so the two-cent piece became the first United States coin to bear the phrase. A law of March 3, 1865 extended it to every coin large enough to carry it.
The coin was welcomed at first, but its moment passed quickly. The copper-nickel three-cent piece arrived in 1865 and the five-cent nickel in 1866, and the two-cent mintage fell every year after 1864. Surplus coins could not be redeemed until a law of March 3, 1871 allowed it in lots of $20. The 1872 circulation mintage was just 65,000, and the Mint Act of February 12, 1873 abolished the denomination. About 17 million of the roughly 45.6 million issued had been redeemed and recoined into cents by 1909.
