4 Escudos - Fernando VI

Fernando VI's accession in 1746 brought immediate pressure on colonial mints to update their coinage, and the Mexico City facility — already the most productive gold mint in the Spanish empire — adapted quickly. The 1747 date places this piece in the earliest years of his reign, before the administrative reforms of the 1750s began standardizing output across New Spain's minting operations.

Cob-style production had long since given way to milled coinage at Mexico City by this point, but quality control remained inconsistent enough that planchet irregularities are frequently encountered on this type.
