Ferdinand VI Real 1751 Mo-M MS63 NGC, Mexico City mint, KM76.1. Choice Uncirculated with partially reflective surfaces and golden toning on the obverse, while the reverse is more darkly patinated. A most attractive example of this type, conditionally very rare in this preservation with only two finer coins (both MS64) of the type listed in NGC's current census, and thus eminently desirable.
