The pinchbeck metal medalion commerating the capture of Portobello in Panama by Admiral Vernon and Commodore Brown in 1739. It is toned to a rich brown and is in F-VF condition for its age and near as struck with minor dings. A scarce early military medallion and seldom seen. Similar to Mitchner 5047 and 37 mm in diameter. Historically this is a very interesting piece as it reflects the continuing struggle between Spain and England over American trade. The more general struggle of the War of the Austrian Succession will not break out until next year. Although sold as a commerative and not an official issue to combattants, this is clearly a precursor to the numerous campaign medals of the 19th and 20th centuries.
