10 Réis - Joao V Lisbon mint

Historical Context: This 10 Réis copper coin was issued for Angola during the extensive reign of Dom João V, King of Portugal (1706-1750), often referred to as "the Magnanimous." The specified date range of 1715-1749 places its production firmly within a period of immense imperial wealth for Portugal, primarily fueled by gold discoveries in Brazil. Though minted in Lisbon, the coin's Angolan attribution underscores the vital role of Portugal's African colonies in its vast overseas empire. Such base metal coinage facilitated daily commerce within the colony, reflecting the central government's control over colonial economic systems and the need for small change in a burgeoning trade network.

Artistry: The design of this 10 Réis piece, a product of the Casa da Moeda de Lisboa, adheres to the established numismatic iconography of the Portuguese Baroque era, albeit simplified for copper issues. The obverse typically features the crowned royal arms of Portugal, comprising the escutcheons of the five quinas and the seven castles, often encircled by a laurel wreath or similar ornamentation. The reverse usually displays the denomination, "X REIS" or "10 REIS," and the date, frequently within a decorative cartouche or wreath. While specific engravers for these colonial copper issues are rarely individually documented, the overall style reflects the formal, heraldic aesthetic prevalent in Portuguese coinage of the early 18th century.

Technical/Grading: Struck on a copper flan measuring 31mm in diameter and weighing 7.64 grams, this denomination often exhibits considerable variability in strike quality. Key high-points for assessing wear include the intricate details of the crown, the individual quinas and castles on the shield, and the delicate elements of any surrounding wreath. On the reverse, the serifs and outlines of the numerals and lettering are critical. Due to the nature of copper and the pressing techniques of the period, specimens frequently display planchet imperfections, areas of weak strike, and surface corrosion. A well-centered strike with full detail on the crown and shield is considered exceptional for this type.
