Aureo sale 238, lot 576

This specimen was lot 576 in Aureo & Calicó sale 238 (Barcelona, November 2011), where it did not sell. The catalog description[1] noted,

"1820. Zacatecas. RG. 8 reales. Parte de brillo original. Magnífico ejemplar para esta pieza. Muy escasa así. (EBC-). (Eight reales of 1820, Zacatecas mint. Partial luster, magnificent example for this date, very scarce thus, nearly extremely fine.)"

Alarmed by the outbreak of the Mexican war of independence, local officials opened a mint in Zacatecas so that silver ore would not have to be transported over bandit infested mountain trails. This bust type was struck 1813-22 and is rare in nice condition as most were poorly made. By 1818, techniques had improved to the point where reasonably well struck specimens are available. Assayers AG (1814-20) and RG (1820-22) are both recorded for the date.

Recorded mintage: unknown but common.

Specification: 27.07 grams, 0.896 fine silver, .780 troy oz ASW.

Catalog reference: Cayón-16032, Cal. 696, KM 111.5.
