Great Britain
William & Mary gold 5 Guineas 1691, S-3423, Elephant & Castle hallmark, Tertio edge, AU Details "Rim Filing" NGC, although the cataloguer is puzzled over what is meant by "rim filing" as both rims look normal, as does the edge, as do the surfaces. Sharp images, light old abrasions (including on the rims) under the rich reddish gold toning. The hallmark is especially bold in detail, and overall the coin is fairly choice, and rare. Only one style of the jugate busts appears on the 5-guineas of this reign.
