Bolivia 1675-P E 8 reales
This specimen was lot 22276 in Stack's Bowers NYINC sale (New York, January 2020), where it sold for $780. The catalog description noted, "BOLIVIA. Cob 8 Reales, 1675-P E. Potosi Mint. Charles II. PCGS VF-30 Gold Shield. Dually dated and struck on a heart-shaped flan that is very similar in appearance to the presentation issues that obviously received more care and attention. Perhaps coincidentally produced this way or possibly struck on a left-over cast flan. Ex: Charles L. Ruby Collection." Cob eight reales were struck at Potosi for Charles II 1667-1701 and are generally very crude. A few presentation pieces, round and fully struck, were made every year; these are today called "royals" atho it is uncertain if they were actually presented to the king in Madrid. The surviving "royals" today are nearly always holed or plugged as they were saved as part of a necklace. Assayer E operated 1651-78.
