BOLIVIA. "Royal" Presentation Cob 8 Reales, 1666-P E. Potosi Mint, Assayer Antonia de Ergueta (E). Philip IV. NGC VF Details--Plugged. KM-R21; Lazaro-177 (same dies); Cal-1434. This handsome and nicely preserved example boasts a strong central strike with a bold full cross, but with minor doubling on the pillars, on a broad round planchet. The legends are nearly complete with only minor portions of the some of the letters off the flan, though the two middle digits of the date at 7 oclock are somewhat weak. Close inspection of the surfaces and design elements does not reveal any overt evidence of being plugged; indicating a skilled and tasteful repair long sense toned over. Despite its shortcomings a pleasing survivor of this <strong>RARE</strong> date displaying rich mottled gray and slate patina offering much originality. From the Pat Johnson Collection.
