MEXICO, Mexico City, gold cob 4 escudos, 1680/79 L, Jeweled Cross (1680-98), unique, PCGS AU55, ex-1715 Fleet. S-M29; Cal-939 var (Type 163); KM-54; Fr-3. 13.41 grams. This important coin represents the first known gold issue of the Mexico City Mint, as it bears a visible date of 168 with a digit 7 under the 8, hence 1680/79 (not specified on label). While it is known from documents that gold began production in 1679, only one coin has been attributed to that date (a 1 escudo), and an article by Philip Flemming in the March 2013 issue of the U.S. Mexican Numismatic Association's Journal proves that that coin is of a later style. No other 1680s in any denomination are known, let alone the overdate 1680/79 as we see here. The "jeweled" cross and shield are bold and full, as is the oXML, with most of the peripheries flat and showing blunted edge-points (as made), light yellow in color and somewhat lustrous. From the 1715 Fleet.
