20 Réis - João V (Crown with 4 Arches; Lisbon)

The 20 Réis coin minted in 1715 reflects the height of the Portuguese colonial administration in Brazil during the reign of João V. Struck at the Lisbon mint for circulation within the colonial economy, this denomination was part of a robust copper coinage system designed to facilitate daily trade and commerce in an era defined by the massive influx of gold from the Minas Gerais mines. The coin serves as a physical testament to the mercantilist policies of the Portuguese Empire, which sought to standardize currency throughout its overseas territories.

The design features the crowned shield of the Portuguese coat of arms, a symbol of royal authority that remained remarkably consistent across the period. The crown, distinguished in this specific issue by its four arches, reflects the baroque sensibilities of the early 18th century. While the name of the specific engraver remains obscured by the passage of time and the anonymity of colonial-era mint workers, the craftsmanship is representative of the high output and strict metallurgical standards demanded by the Lisbon mint to support the administrative needs of the Brazilian colony.
