Great Britain, copper alloy Admiral Vernon medal, 1739, Vernon and Brown / Porto Bello, extremely rare, ex-Adams. AC-PBvb4F. 15.21 grams; 38 mm. Dark XF+ with nice surfaces (parts of rims crude) but Vernon's face is somewhat flat, no rarity rating given in AC but with note "known only by the medal illustrated above and another in the Medina-Ferrari-Chao collections," and since the present piece is neither, it must have been a post-publication discovery. XRF: 49.19% copper, 47.25% zinc, 2.86% lead. Pedigreed to the John Adams Collection (with his handwritten tag) and to the Stack's auction of January 2010, with original lot-tag 4677.
