1/2 Real - Fernando VI

Fernando VI never visited the Americas, and his reign saw the Spanish crown intensify Bourbon administrative reforms that would eventually destabilize colonial loyalty across New Spain. The Mexico City mint operated under the assayer system during this period, meaning each coin carries the initials of the assayer personally responsible for its silver content — an accountability mechanism with real legal teeth, as assayers could be prosecuted for short weights.

The half real was the smallest silver denomination in everyday colonial circulation, used heavily in petty trade and wages. Surviving examples in collectible grades are underrepresented relative to larger denominations, largely because the cob-style macuquina format of earlier issues had only recently given way to the milled coinage mandated by Philip V in 1732.
