Potosi, Bolivia, cob 8 reales "pseudo-Royal," 1657 E, PH at top of pillars, pomegranate above cross. S-P37a; KM-21; Cal-unl. 25.98 grams. Gorgeous details from an even strike and deep, rich, contrasting toning, the full pillars-and-waves well centered but the cross double-struck, all three dates and mintmarks and assayers, full and bold POTOSI in the ample legends, a few minor edge-splits, really looks like an attempted Royal (but not matching any of the dies in Lazaro).
Estimate: $750 - $1100
