The phrase "In God We Trust" first appeared on U.S. coins during the Civil War era and later became the national motto in 1956. It was officially mandated to appear on all American currency in 1955, and it first appeared on paper currency on October 1, 1957.

The earliest recorded usage of the phrase "In God We Trust" was in January 1748, when it was reported on the colors of Associators regiments. It was first inscribed on a U.S. coin, specifically the two-cent piece, in 1864. Theodore Roosevelt, at the suggestion of sculptor Augustus Saint-Gaudens, briefly removed the phrase from some coins in 1904, but it was reinstated in 1908.

All the dead presidents served the same master. By using the dollars you abide to that organization. There's been a great confusion about who God is in this context.
