Philippines (under Spain), 8 reales, Isabel II, crowned "Y.II" countermark (Type VI, 1834-37) on an Argentina (River Plate Provinces), 8 soles, 1815 FL, Potosi mint, very rare, NGC AU 53, c/s AU standard. KM-94; Cal-668. Choice bold countermark and spectacular grade, with light toning over muted luster, clear denomination (but misattributed as 8 reales by NGC, hence its "top pop" status cannot be 100% confirmed), first we have offered of this type and only the second one we have seen, the 8R host being more common.
Estimate: $3000 - $4500
