1907 United States Assay Commission Medal. By Charles E. Barber and George T. Morgan. JK AC-51. Rarity-5. Silver. MS-62 (NGC).40 mm x 55 mm, plaque. Appealing deep steel-gray surfaces overall. The 1907 Assay Commission medal (or plaquette, due to its rectangular shape) features the same half length bust of Theodore Roosevelt facing left that was used on the Assay Commission medals of 1904, 1905, 1906, and which would be used again in 1908. The present example is quite scarce, as it is one of just 55 pieces produced in silver.From the Larry Baber Collection.
