1935 United States Assay Commission Medal. Bronze. 51 mm. By John R. Sinnock. JK AC-80a. Rarity-5. Edge Incuse WILLIAM R. SINER. MS-64 (NGC). Mottled rose-orange patina enhances a base of warm golden-tan; the lower reverse is bolder olive-gray. The appearance is smooth, satiny, and visually appealing.The obverse die of this issue is signed J.R. SINNOCK. F. A.D. VIVUM. MXMXXXIV, which translates as "J.R. Sinnock, Engraved From Life 1934." Obviously President Roosevelt sat for Sinnock in person rather than the engraver having to create this likeness through the usual photographs. The reverse is similar to that used for Mint Director Nellie Tayloe Rosss medal and, while it is generally believed that she is the model for the seated figure, there is no proof of this.
