The coin features the third reverse (tails side) design in the six–year Preamble Series.

The 2011 coin design is emblematic of the theme “To Insure Domestic Tranquility,” the third principle in the Preamble.

She bears a a stalk of wheat in her left hand, as she extends her right hand to a landing dove, representing the fulfillment of tranquility in our Nation’s cohesive yet free society. Inscriptions are
