Wrong! The correct answer is: 1957.
In 1955, Congress passed a law requiring that "In God We Trust" appear on all U.S. coins and currency. The first paper currency with the motto appeared in 1957. This was right after the McCarthy era, during the early Cold War, when no congressperson would dare be seen voting against "God." "In God We Trust" did appear occasionally on a few coins, starting with a 2-cent piece in the 1860s, in an attempt (it is surmised) to put "God" on the side of the north during the Civil War. In 1956, an Act of Congress adopted "In God We Trust" as a national motto. The original motto, "E Pluribus Unum" ("out of many, [come] one,") celebrating plurality, still appears on the Presidential Seal and on some paper currency.
