1890 United States Assay Commission Medal. Silver. 33 mm. By Charles E. Barber and George T. Morgan. JK AC-33a. Rarity-4. MS-62 (NGC). Bright antique silver surfaces with a sharp strike and a smooth appearance for the assigned grade.The bust of President Benjamin Harrison featured on the obverse of this issue is a reduction from that used on the Presidential medal (Julian PR-24), also the work of Charles E. Barber. The mintage of this issue in silver is at least 26 pieces, to fill the 26 medal cases that the Mint purchased from Knecht and Boyer. The unique velvet case was likely intended for President Harrison; the other 25 cases were in leather. From the Richard Jewell Collection.
