BOLIVIA. "Royal" Presentation Cob 8 Reales, 1652-P E(E-E). Potosi Mint; Assayer Antonio Abando (A/F-O/N) and Antonio de Erueta (E-E). Philip IV. NGC EF Details--Environmental Damage.

KM-R-A20.2; Lazaro-118 (same dies); Cal-1405; cf. Calb-1038. Transitional second type of 1652; legend in three lines. The sole certified example of the type on either the NGC or PCGS population reports. Seldom encountered and highly coveted, this EXTREMELY RARE type is the direct result of the Potosi mint scandal. This moderately worn somewhat crude issue, struck on a broad round planchet, retains most of the design features. A few areas of weakness are noticed, but with bold pertinent details. Close inspection reveals both sides have areas with slightly granular surfaces accounting for the details designation. Despite its shortcomings this highly desirable type offers a pleasing appearance displaying rich mottled slate gray patina with areas of brighter coloration.
