Fugio Cent Mind Your Business Copper Penny Plaque

On April 21, 1787, the Continental Congress of the United States authorized a design for an official copper penny, later referred to as the Fugio cent because of its image of the sun shining down on a sundial with the caption, "Fugio" (Latin: I flee/fly). This coin was reportedly designed by Benjamin Franklin; as a reminder to its holders, he put at its bottom the message, "Mind Your Business". The image and the words form a rebus meaning that time flies, do your work. This design was also used on the "Continental dollar" (issued as coins of unknown real denomination, and in paper notes of different fractional denominations) in February 1776.
