Great Britain 1792 guinea
This specimen was lot 31001 in Heritage sale 3064 (Chicago, April 2018), where it sold for $2,160. The catalog description noted, "George III gold Guinea 1792 MS63 NGC, Royal mint. A striking example by all accounts, complete with satiny surfaces that display beautiful amber color at the peripheries and a few scattered marks that align with the grade. The portrait of the King remains bold, as does the reverse shield design, further aiding in its exceptional appearance. As the single-finest example graded, a rather exciting opportunity for the specialist." 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.
