Bolivia 1657-P E real
This specimen was lot 76587 in Stack's Bowers Collectors Choice Online Auction (Costa Mesa, CA, February 2025), where it sold for $145. The catalog description[1] noted, "BOLIVIA. Cob Real, 1657-P E. Potosi Mint. Philip IV. PCGS VF-30." Cob one reales were struck at Potosi with this design for Philip IV 1652-66 and are generally very crude. As part of the reform of 1652, the date was moved to the center of the obverse, greatly increasing the percentage of production with legible dates. Assayer Ergueta ("E") is known for 1651-78. A few presentation pieces, round and fully struck, mostly eight reales, were made every year; these are today called "royals" altho 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.
