BOLIVIA. "Royal" Presentation Cob 4 Reales, 1749-P q. Potosi Mint, Assayer Luis de Quintanilla (Q). Ferdinand VI. NGC AU-50. KM-R39(royals not listed); Cal-396. Weight: 13.13 gms. The only example certified on either the NGC or PCGS population reports. <strong>EXTREMELY</strong> <strong>RARE</strong> and very attractive, this wholly original looking survivor is vastly superior than normally encountered from this series. The strike is bold on a compact flan with well-formed and nicely defined design features displaying beautiful old cabinet patina with a slight iridescent sheen that pops out when rotated in the light. Seldom are pieces from this series encountered in this high state of preservation without any problems that usually plague these special issues. Serious consideration should be given by potential bidders who are seeking nicely preserved numismatic relics to add to their collections. From the Pat Johnson Collection.<p>Purchased privately from Freeman Craig circa 1970s.
