Seville, Spain, 4 reales, Ferdinand-Isabel, assayer Gothic D on reverse, NGC MS 64, finest known in NGC census. CT-211. 13.64 grams. Beautiful sharp detail all over, the reverse 100% full but the obverse slightly off-center (and slightly doubled), no wear at all and in fact the highest grade we have seen on any coin of this period, with lovely original mint luster and bluish toning at rims, hands down the finest.
