1963 United States Assay Commission Medal. Silver. 57 mm. By Gilroy Roberts and Frank Gasparro. JK AC-107a. Rarity-7. Edge Incuse FREDERICK W. TATE. MS-68 (NGC). Handsome pewter gray patina is seen on both sides of this lovely sandblast-finish specimen. The surfaces are virtually pristine.The reverse design of this issue, showing Assay commissioners engaged in weighing and counting coins, is the only accurate depiction of the actual work of the Commission to appear in this long series, and ranks as one of Gasparros best works. The obverse is a reduction of the regular secretary of the Treasury medal for C. Douglas Dillon. According to the Julian-Keusch reference, this was the last Assay Commission medal to be struck only in silver. Examples are rare, and this is the only specimen that we have handled in at least a dozen years. It is the Keusch specimen, originally presented to Frederick W. Tate, deputy director of the Mint in 1963 under Director Eva Adams. Our (Bowers and Merenas) November 1995 sale of the Roger M. Fred, Jr. Collection also included an example of JK AC-107 as lot 1150.In 1963 the Assay Commission, which met on February 13, included a number of prominent numismatic personalities: Elston G.
