On April 21, 1787, the Congress of the Confederation of the United States authorized a design for an official copper penny,[3] later referred to as the Fugio cent because of its image of the Sun and its light shining down on a sundial with the caption, "Fugio" (Latin: I flee/fly, referring to time flying by). This coin was designed by Benjamin Franklin; as a reminder to its holders, he put at its bottom the message, "Mind your business". This design was based on the 1776 "Continental dollar" coin, which was produced in pattern pieces but was never circulated.[4]
