This specimen was lot 89 in Sedwick sale 20 (Winter Park, FL, November 2016), where it sold for $19,100. The catalog description noted, "Potosi, Bolivia, bust 4 escudos, Charles IV, 1791PR, laureate bust (very rare), encapsulated NGC AU 58, finest and only known in NGC census. Superb strike and lustrous fields, exceptionally detailed (per the very rare one-year design) with just the highest points slightly flat (not really wear). With a mintage of only 170 pieces (both laureate and non-laureate types) this date is the rarest bust-type issue in any denomination from this mint. This specimen is clearly a trophy gem and has no equal in any sales records known to us. NGC certification #4431905-001."
While silver coins from Bolivia exist in vast quantities, gold from Bolivia is scarce. For the colonial period, Colombia may be regarded as the most prolific issuer, followed by Mexico, followed by Peru. Bolivia, Chile and Guatemala are minor sources. This type, with a laureate bust of Charles IV, was minted 1791 only and is very rare. The standard bust was minted 1791-1808 and is scarce.
Recorded mintage: unknown.
Specification: 13.54 g, .875 fine gold, .380 troy oz AGW.
