This specimen was lot 21096 in Heritage sale 3010 (Boston, August 2010), where it sold for $2,185. The catalog description[1] noted, "George III gold Guinea 1791, MS63 NGC, superb mint brilliance with minimal contact marks, rare grade for this heavily circulated type." This type, the commonest of several used during George's long reign, is noted for 1787-99. The reform of 1817 terminated all guinea-denominated issues in favor of the sovereign. At that time the guinea, which heretofore had varied in value, was fixed at 21 shillings.

Recorded mintage: unknown.

Specification: 8.35 g, .917 fine gold, .246 troy oz AGW.

Catalog reference: S3729, KM 609.
