 Now through Sunday, August 11th, the U.S. Mint invites the public to vote for the additional six D.C. superheroes they would like included in this special series. Public participation ensures that this multi-year series represents and reflects the most beloved of the D.C. superheroes. The U.S. Mint has a long tradition of producing coins and medals that honor American values, icons, and significant moments in history. This alliance with D.C. acknowledges the role of comic art in reinforcing American ideals.
