Watch List notes:

COMMEMORATIVE MEDALS, BRITISH MEDALS, Admiral Edward Vernon, Rear Admiral Sir Chaloner Ogle and Brigadier General Thomas Wentworth, the Capture of Carthagena, Pinchbeck Medal, 1741, three standing figures, Vernon in centre, with lions at his feet, rev Panorama of Carthagena, fort in centre, 38mm (Adams PBvow1A; McG 176; Betts 309; cf Ford XIV, 558, sold for US$6000). An excellent example but weakly struck and lacking high spots, better than very fine and very rare.
The editors of Betts added the footnote "The figures on the obverse might be characters in some extravaganza and represent the "art" of the entire series ..."

Estimate: £250-350
