Ferdinand VI gold 4 Escudos 1750/48 Mo-MF AU Details (Obverse Repaired) NGC, Mexico City mint, KM137, cf. Cal-107 (unlisted overdate). Rather sharply detailed, with a very clear overdate and evidence of tooling on the obverse defining the grade. The reverse remains very attractive with old orange-gold patina and significant remaining luster. A decent example of this very rare overdate variety, and one of very few specimens seen by the cataloguer, with no specimens listed on the current combined census of the major third party grading services.From The Rudman Collection of Mexican Coins
