1739 Admiral Vernon Medal. Porto Bello Medals with Vernons Portrait and Icons. Copper. 37.7 mm. Adams-Chao PBvi 6-G, M-G 98. Rarity-5. Plain Edge. AU-58 (NGC). Satiny and hard surfaces are smooth in hand and exceptionally attractive for an example of this type. Predominantly antique copper in appearance, glints of faded antique gold are evident here and there around the peripheries, especially on the obverse. Sharply to fully defined overall and not all that far from Mint State. We offered another NGC AU-58 example of PBvi 6-G in our New York Americana Sale of January 2011 that brought $747.50. The present example is far finer despite the identical grade and worthy of a strong premium.
