Coin Description: Potosi 1690 P Eight Reales. 25.7 grams. El Peru, mint of Potosi. An Eight Reales struck in the 25th year (1690) of the reign of Carolus II. The mint mark (P) and the assayer’s initials (VR for Pedro de Villar) appear three times and the date (690) twice on this well struck specimen. Obverse well struck and centered with clear date and other details apparent. The cross side is also well centered with almost a complete cross and date. Lion and castles well positioned and visible with some flattening. Overall an exceptional piece.
