MEXICO. "Royal" Presentation Cob 4 Reales, 1643-Mo P. Mexico City Mint, Assayer P. Philip IV. NGC AU-53. KM-R41; Cal-1050; Pelicer-923. Weight: 14.03 gms. The only example certified on either the NGC or PCGS population reports. An incredibly pretty presentation piece struck on a somewhat compact heavy planchet with slightly misaligned dies. Nearly every design detail is struck up and like most "Royal Coinage" the cob is round. Rich patina graces both sides of this very eye appealing and <strong>EXTREMELY</strong> <strong>RARE</strong> coin with minor earthen deposits amongst the devices and in the crevasses. Wholly original looking and attractive, this beautifully preserved specially prepared issue is sure to excite advanced collectors seeking high caliber numismatic treasures. From the Pat Johnson Collection.
