MEXICO. 8 Reales, 1784-FF. Charles III (1759-88). NGC AU Details--Chopmarked.KM-106.2; FC-68; El-95; Cal-Type 103#935. Sharply struck and dazzling in the fields with a small chop just to the left of the one in the date and a second chop inside the "O" of "CAROLUS". Nonetheless, a coin that is sure to stop the specialist in their tracks, as the FF assayer issue for 1784 is the key to the series and rarely becomes available in any grade.<p>NGC AU Details--Chopmarked.
