Mexico (1556-98)-Mo O 8 reales
This specimen was lot 39330 in Stack's Bowers Winter sale (Baltimore, November 2015), where it sold for $1,292.50. The catalog description noted, "MEXICO. 8 Reales, ND (1556-98) Assayer O. Philip II (1556-98). NGC VF-35. Full crisp crown atop a clear shield. Nice round flan with good centering and virtually no strike doubling. Nearly full legends on both sides. Tone within the recessed areas providing a nice contrast to the devices. A fully original coin that has never seen saltwater like so many of other examples of the issue. An exceptional example of this type. Pedigree: From the David O'Harrow Collection." This type was not dated and the terms of service of the various assayers ("O" in this case) are still hotly disputed. In 1728, cobs were debased from .931 to .917 fine silver.
Recorded mintage: unknown.
Specification: 27.07 grams, .931 fine silver, .810 troy oz ASW, this specimen 27.4 g.
