Watch List notes:

Potosi, Bolivia, cob 8 reales, Philip II, assayer C below erasure, very rare. S-P5; KM-5.1; Cal-671. 27.03 grams. Broad flan with choice full shield boldly flanked by P-erasure-C (the erasure clearly containing at least some combination with assayer B) to left and denomination o-VIII to right, choice full cross-lions-castles and tressure, some legend despite peripheral flatness, beautifully toned XF, an excellent example of this traditional rarity that was claimed by Sellschopp to be evidence of striking in La Plata, an error that was publicly eradicated by Cunietti in 1988 but still persists in older catalogs and references.

Estimate: $3000 - $4500
