Ferdinand VI 4 Reales 1751/41 Mo-MF VF Details (Damaged) NGC, Mexico City mint, KM95. Rather well detailed, yet with tooling evidence above the crown on the obverse, possibly removed from jewelry. A very rare date in any grade, missing altogether in Norweb, Gerber and Patterson. Only one coin of this date is currently listed in NGC census (an XF40 example).
Estimate: 200-300 USD
