GREAT BRITAIN. 1/2 Guinea, 1801. London Mint. George III. NGC MS-62.S-3736; Fr-363; KM-649. Giving an amazing appearance for these often widely travelled pieces, this Mint State beauty is well struck and highly reflective. The golden yellow hue of the luster is scarcely broken by contact, and altogether is an amazing piece that is a prize for any British collection.
