GREAT BRITAIN. Guinea, 1774. George III (1760-1820). NGC PROOF-61.Fr-355; S-3728; KM-604. A lightly handled proof of the date, easily identified as such by a sizable internal cud beneath the "T" in "ET" on the reverse that appears on most examples. A few small rim knocks, while permissible at the assigned grade level, are mentioned for the sake of completeness.NGC PROOF-61.
