Great Britain
George II gold 2 Guineas 1739 AU58 NGC, Royal mint, KM578, S-3668. A highly lustrous example, on the cusp of Mint State, with strong design features, very few individually identifiable marks and almost imperceptible hints of friction on the highpoints. An altogether excellent selection for the savvy collector, as the technical designation suggest a lower price point than a low-end Mint State example, but the eye-appeal is almost certainly every bit their equal.
