5 Réis - Maria I (Large Type; Low and High Crowns; Lisbon)

The 5 Réis coin minted in 1786 reflects the transition of the Portuguese Empire under the reign of Queen Maria I, the first undisputed queen regnant of Portugal and Brazil. Struck at the Lisbon mint for use in the colonial Brazilian market, this piece belongs to a broader series of copper coinage intended to facilitate everyday trade and small-scale transactions within the territory. The period was marked by administrative attempts to standardize the complex currency systems across the Portuguese Atlantic, with these coins serving as the workhorse of the local economy.

Design-wise, the coin features the characteristic heraldry and crown motifs common to the Maria I era, often categorized by collectors into variations of 'low' and 'high' crown types. These designs were produced by the Royal Mint in Lisbon, following traditional European numismatic styles of the late 18th century. While the coins were mass-produced for circulation and often exhibit significant wear from decades of heavy use, they are regarded by historians as essential artifacts representing the direct economic influence of the Portuguese Crown on its overseas colonial administration prior to the relocation of the court to Brazil.
