Segovia, Spain, milled 8 reales, Philip IV, 1660BR, vertical aqueduct, encapsulated NGC AU details / scratches. KM-76; CT-591. Impressively huge flan (extending well past the rims), with good full details enhanced by toning, the fields positively rife with stress lines from striking, trivial scratches on lions and castles within the cross.
Estimate: $600 - 900
