GREAT BRITAIN. 2 Guineas, 1740/39. London Mint. George II. PCGS AU-55 Gold Shield.S-3668; Fr-337; KM-578. A delightful overdate issue, this exceptionally pleasing piece presents evidence of light handling upon the high points, though a good deal of luster in the fields remains. Further accentuating this coins charm is the attractive tone which it has developed, offering hints of magenta and burgundy throughout.
