Great Britain
George III gold Proof Guinea 1787 PR60 NGC, KM609, S-3729, W&R-104. Highly reflective and quite attractive despite the grade, this piece shines with a pleasant honey-golden color. As the surfaces are relatively exempt from distracting contact marks and hairlines, it would seem that the assigned grade was given due to the evident light friction appearing on the high points throughout. Light mechanical doubling is visible as a result of the piece having been struck twice. An interesting piece and worthy of examination.
