Lot of (3) Uniface Cliches of Standard U.S. Mint Assay Commission Medals. Mint State.Included are: the obverse of the 1922 issue, AC-66; the reverse of the 1927 issue, AC-71; and the reverse of the 1922 Assay Commission Medal, AC-73. All are in their original 51 mm size, are less than .5 mm thick, and bear an incuse, reversed version of the obverse design on the back. Finished in what looks like the typical U. S. Mint Medal color and finish, these may have had some official purpose. At any rate, quite intriguing, and certainly rare.
