George III (1760-1820), Oval countermark struck on a Spanish Eight Reales of King Charles III, 1778 FF, Mexico City (Mexico) mint, toothed border both sides. Oval George III hallmark embossed on bust of Spanish King facing right, date below, legend surrounding CAROLVS III DEI GRATIA. Rev, crowned quartered shield of arms, pillar with ribbon motto either side, legend reads HISPAN ET IND REX M 8R FF (S.3765A; ESC 129; Bull 1852 Obv A/Rev 2).
An ever appealing piece within the emergency issues of George III, a near centred countermark. Host coin a comprehensive example of the year, some natural wear to the high points. Reverse pleasing with some metal stress to the left hand side near the Mexico mint mark. Countermark near extremely fine, host coin about very fine.
