The inscriptions read "Puerto Rico", "Isla del Encanto" (Isle of Enchantment), "E Pluribus Unum", and the date. The reverse of the coin was designed and sculpted by Joseph Menna.
The obverse design of the coin will continue to use the rendition of the George Washington from the prior 50 State Quarters Program, which was designed by John Flanagan after the William Cousins original.
