The 1772 date on this type marks a hard break in Spanish colonial coinage: that year, Carlos III mandated the transition from the cob ("macuquina") format to the milled portrait coinage, with Mexico City among the first American mints to comply. The reform was partly administrative — cobs were nearly impossible to counterfeit-proof — and partly imperial vanity, as the king wanted his likeness circulating across the Atlantic world.
These pieces saw extraordinary geographic reach, trading hands in Canton, Philadelphia, and Calcutta with equal legitimacy. The United States formally recognized the 8 Reales as legal tender until 1857.
