At the official auction of the New York International Numismatic Convention, crossing the block as lot 11306 is a historic landmark among Colombian coins. It is the only known example of the first milled 4 Escudos of Colombia. It is nicely toned with orange and coppery highlights around the peripheries of both sides. It is struck sharply and nicely lustrous for the grade, with some reflective texture visible on the obverse and some shining on the protected area of the reverse.
It features Denticles frame on both sides, but those at the upper left obverse are the longest. A short scratch crosses the field above 17 of the date, and a dull scrape is present between the crown and EQ of SEQUORS, but otherwise, no notable marks are seen. Also, no planchet flaws or striking anomalies are present, it truly represents the skill of the mint workers in Bogotá and their ability to develop a fine product.
However, traditional interpretations of the technological changeover suggested that hammered cob coinage stopped before milled coinage began. However, the existence of both hammered and milled coins dated 1755 suggests that the transition was more gradual, even that the two genres of coins were struck contemporaneously. When no one had discovered the coin, students of this series knew there was a good possibility of a milled survivor from 1755. A.M. Barriga Villaba’s Historia De Las Casa De Moneda records that 32 marks of milled gold coinage were produced in Santa Fe in 1755, equal to 2,176 Escudos. That figure is dwarfed by the 8,393 marks of hammered gold coinage produced that year.
Gold cobs of 1755 are extremely rare, and the existence of even a single milled gold coin from Santa Fe’s 1755 mintage is a miracle.
In 2013, lightning struck twice when a 1755-S 8 Escudos was discovered and auctioned by Stack’s Bowers Galleries. Previously unknown and totally new to numismatics, the coin brought $223,250.
If all 32 marks of gold were devoted to 8 Escudo production in 1755, the mintage would have been just 272 coins. If the gold was evenly divided between 8 Escudos and 4 Escudos, the mintages would have been 136 specimens of the Onza and 272 4 Escudos.
This coin has appeared at auction only twice, in 1943 and 2005. No other 4 Escudos from any mint could be considered rarer or more historically important than this one.
