80 Réis - João V (State of Grão-Pará and Maranhão; Crown with 4 Arches; Lisbon)

The 80 réis coin issued in 1749 under the reign of João V reflects the colonial economic policies of the Portuguese Empire in the 18th century. Minted in Lisbon for use specifically within the State of Grão-Pará and Maranhão, this copper denomination was part of a broader effort to provide sufficient small-change currency to facilitate local commerce in the northern territories of colonial Brazil, which were then heavily reliant on trade and resource extraction.

The design features the crowned shield of Portugal on the obverse and the denomination 80 flanked by rosettes on the reverse. The inclusion of the crown with four arches is a hallmark of the period's numismatic style under João V, aimed at reinforcing royal authority across the Atlantic. These coins were produced in significant quantities to circulate alongside higher-value gold coinage, serving as the essential workhorses of the colonial economy during an era when Portugal exerted tight control over the monetary supply of its overseas domains.
