1779 (ca. 1863) Captain John Paul Jones / Bonhomme Richard vs. Serapis. U.S. Mint Copy Dies. Bronzed Copper. 57 mm. Julian NA-1, Adams and Bentley-8, Betts-568. MS-64 BN (NGC).A second example struck from these dies, prepared in the U.S. Mint to replace the earlier gunmetal dies of ca. 1863. Boldly impressed with lovely medium copper patina, a few swirls of variegated color in the obverse field are all that seem to preclude a full Gem Mint State rating.
