MEXICO. 4 Escudos, 1770-Mo MF. Mexico City Mint. Charles III. NGC AU Details--Removed from Jewelry. Fr-30; KM-141; Cal-1806. Bright and well struck, this example is one of only 2 graded by NGC and both are details-graded. The current example has glossy surfaces, and was previous removed from jewelry, but this does not negate its overall rarity. Despite its shortcomings a presentable example of this <strong>EXTREMELY</strong> <strong>RARE</strong> type that seldom appears on the market. From the Pat Johnson Collection.
