Aureo sale 238, lot 436
This specimen was lot 436 in Aureo & Calicó sale 238 (Barcelona, November 2011), where it sold for 230 euro (about US$365 including buyer's fees). The catalog description[1] noted,
"1777. Potosí. PR. 8 reales. Parte de brillo original. Ligero exceso de plata en anverso. Rara así. EBC/EBC+. (eight reales of 1777, Potosí mint. Lustrous, Slight excess of silver on the obverse, rare thus, extremely fine.)"
The year 1773 marked the initiation of bust coinage at Potosi, the last mint to do so, as cobs continued to be produced until 1773. The assayer PR appears for 1776-95. The "excess silver" mentioned in the description is most likely raised lumps formed by rust pits in the die.

Recorded mintage: unknown but common.

Specification: 27.07 grams, .903 fine silver, .786 troy oz ASW.

Catalog reference: Cayón-12049, Cal. 978, KM 55.
