This type was struck 1625-48 at Potosi. While silver cobs from Bolivia are very common, this early type is rare, as most were recalled and melted when it was discovered that the mint operators had been systematically debasing their issues, sometimes as low as .700 fine. This specimen was lot 1147 in Sedwick sale 9 (Winter Park, FL, April 2011), where it sold for $1506.50. The catalog description[1] noted, "Potosi, Bolivia, cob 8 reales, (164)4T, Royal-like. Broad flan with choice full shield and cross (the latter very slightly doubled) and much legend, VF+ with toned fields, clear 4 at end of date, a bit underweight but edges intact, probably a coin that should not have escaped the great recall in 1649. A gorgeous specimen in any case, far better than normal for this period, and well worth a premium."

Recorded mintage: unknown.

Specification: 27.07 g, .931 fine silver (if full fineness), .810 troy oz AGW, this specimen 24.3 grams.
