The 2018 Palladium American Eagle Proof coin was released by U.S. mint on September 6th and it became 'Currently Unavailable' within 5 minutes of the sale opening. 2017 saw the release of U.S. mint's first ever Palladium coin, the 2017 Palladium Eagle bullion coin. The mint set the limit of 15,000 coins only and that's the limit for this years Proof version too. The U.S. mint hasn't confirmed yet if it is releasing the bullion version of the Palladium Eagle this year.
2018 Palladium American Eagle
As we saw in the 2017 Palladium American Eagle Bullion coin, this year's Proof version follows the same design taken from the Mercury dime or the Winged Liberty. The Mercury dime was designed by A. Weinman. It portrays the Liberty with a wreath of curls and a pileus or a Liberty cap. The pileus sports wings that Weinman intended to represent ‘Liberty of thought’! But it caused the famous misnomer - ‘Mercury dime’, as the messenger to the Gods, ‘Mercury’ had wings in his hat!
The reverse design of the Palladium Eagle bears a high-relief version of the 1907 American Institute of Architects (AIA) medal design, again a design of Weinman’s. The AIA Gold Medal, the highest honor that the Institute confers upon an individual or pair of individuals was designed by Weinman in 1907. It’s a tradition that is still being carried out by the AIA. The reverse design has inscriptions of UNITED STATES OF AMERICA, 1 OZ. Pd .9995 FINE, E PLURIBUS UNUM and $25 for the coin’s legal tender face value. The Proof version has a 'W' to denote the West Point mint.
