S-3688 variety, Georgius II type.
A landmark example which is the single finest graded and only MS65 example of this type at either service.
And while this piece is technically superb, with utterly unmarked, gem surfaces, it is also aesthetically sublime, with a lovely, lustrous original patina and delicate pull away color at the legends on the obverse and reverse.
This coin is from the CRO archives and is not currently available for sale.
