The use of IN GOD WE TRUST has not been uninterrupted. The motto disappeared from the five-cent coin in 1883, and did not reappear until production of the Jefferson nickel began in 1938. Since 1938, all United States coins bear the inscription.
A third pattern two-cent piece dated 1863 bears the adopted motto, âIn God We Trust.â But this was created in the 1870s, at the end of the coinâs brief life. Its production might be attributable to collector demand for such a coin after the Congress discontinued the two-cent piece in 1873.
