1922 United States Assay Commission Medal. By George T. Morgan. JK AC-66. Rarity-4. Bronze. MS-63 (NGC).51 mm. Rich golden-rose color is seen on both sides of this attractive, fully defined specimen. A few inoffensive carbon spots are all that preclude an even higher grade. The obverse of this issue is a reduction of the medal for Treasury Secretary Andrew W. Mellon. The reverse, which was also used on the 1943 Assay Commission medal, exhibits a majestic eagle that is similar in style to the 1918 Lincoln-Illinois Centennial commemorative half dollar.
