1739 Admiral Vernon Medal. Porto Bello with Vernons Portrait Alone. Adams-Chao PBv 13-K, M-G 38. Rarity-5. Copper. MS-63 (PCGS).39.9 mm. Exceptionally well preserved for the type, this piece sports warm medium brass color with mottled olive-gray overtones. Nicely made, as well, with a universally bold strike that includes considerable sharpness to Vernons portrait and throughout the reverse design. A few inoffensive spots are all that seem to preclude a higher Choice Mint State rating for this smooth and inviting piece.
