COLOMBIA. 4 Escudos, 1769-PN J. Popayan Mint. Charles III (1759-88). PCGS AU-53 Gold Shield.Fr-26; Restrepo-M64.8; KM-37. A well struck, exceptional example of this issue, historically notable as the final appearance of the portrait of Ferdinand VI on any coin struck in Colombia or anywhere else. The surfaces glow with luster in protected regions and deep violet and coppery orange toning over the fields and devices. The obverse shows a swollen area from die failure in the middle of the right obverse field. Undoubtedly one of the prettiest examples extant of this type.Ex: Eldorado Collection.
