The year 2007 marked the eleventh year of production of the Proof Platinum American Eagle series. The obverse side of the coin was designed by revered U.S Mint sculptor and engraver, John Mercanti and the reverse was designed by the famed U.S Mint sculptor and engraver, Thomas D. Rogers. In 2007, the Mint Struck just over 8,000 one-tenth ounce proof Platinum American Eagles, and less than 5% of those pieces have achieved the perfect PF70 grade by NGC. Fractional platinum is sought after by investors and collectors across the world because they are no longer in production by the U.S Mint.
