Watch List notes:

Potosi, Bolivia, cob 1/4 real, Philip II, assayer L to right, mintmark P to left, very rare. S-P3; KM-unl; Cal-109. 0.87 grams. Very broad flan with full legends showing all five commas as stops between words and evident ISPAN without H, also full crowns and bold full inner details, lightly toned AXF, arguably the finest of six known of this very rare assayer Alonso Lopez Barriales (missing in Sellschopp), who in 1577 had been removed from office and fined under charges of fraud, the prosecutor actually asking for death penalty and confiscation of his entire estate.
