Santiago, Chile, bust 8 escudos, Ferdinand VI, 1751J, very rare variety lacking rosettes on reverse, from the Luz (1752), encapsulated NGC MS 62. KM-unl. (cf. 3); CT-unl. (cf. 72). Somehow this eye-catching variety has escaped notice by the general reference books, but of course it does appear in Carlos Jara's specialized catalog (p. 344), and several examples appear in the Sotheby's auction of March 1993, with only about 10-12 known overall. This specimen is somewhat typical in showing bright luster but central areas of weak strike, with slight flan-bulge and die-crack in upper half of obverse, still probably among the best examples known of this rarity. From the Luz (1752).
Estimate: $5000 - 10000
