The year 2007 marked the eleventh year of production of the Proof Platinum American Eagle series. The U.S Mint continues its design series for the Proof Platinum coin entitled “The Foundations of American Democracy”, which honors the three branches of government. The second design recognized the executive branch. A bald eagle depicted with its wings spread representing freedom, a shield at its chest ready to enforce laws and guarantee those freedoms. In 2007 the Mint struck 25,519 one-half ounce proof Platinum American Eagles which represented over a 300% increase in overall mintage when compared to the previous year. This significant increase was due to the Mint releasing a special two coin 10th Anniversary set which included a one half ounce proof and reverse proof versions, which in turn became the highest selling Platinum Proof product in years. Less than 4% of the coins struck have received the perfect PF70 grade by PCGS.
