Mexico H3064-31311r.jpg

This specimen was lot 31311 in Heritage sale 3064 (Chicago, April 2018), where it sold for $3,760. The catalog description[1] noted, "Charles & Johanna 'Late Series' 4 Reales ND (1542-57) M-S XF Details (Surface Hairlines) NGC, Mexico City mint. Placed on a broad flan with full legends and displaying variegated brown and silver tone over both sides. Some strike doubling, mostly confined to the centers, is noted along with a mixture of hairlines from an previous improper attempt at cleaning. Despite its flaws, perhaps finest known quality for this very rare 'S' assayer variety, it being only the second we've seen, the other being a heavily corroded, barely legible example that appeared in a 2012 Stack's Bowers auction (Sale 164 - Lot 2674) and brought $550 hammer. Selections from the Isaac Rudman Numismatic Cabinet." 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: 13.53 grams, .931 fine silver, .405 troy oz ASW, this specimen 33 mm diameter.

Catalog reference: KM0018, Cal-Unl., Nesmith-78.
