Bolivia 1640-P TR 8 reales
This specimen was lot 23134 in Heritage sale 3020 (Long Beach, September 2012), where it sold for $3,055. The catalog description noted, "Felipe IV Royal Cob 8 Reales 1640 P-TR, VF, slightly double-struck on the obverse but with bold details, lightly gilt and holed at one edge. Very rare, clear date and King's name." Royals are known of this type from the Potosi mint for 1630-48 but all are rare. The regular cob issues are not nearly as nice. The 1649-52 was a period of reform at the Potosi mint; it was found that the previous mintmasters in office 1625-48 had been debasing the cobs, a crime for which one official paid with his life. However, one may presume that a presentation piece such as this would not be trifled with.
Recorded mintage: unknown.
