10 Réis - João V Goa mint

Historical Context: This 10 Réis copper coin was issued during the reign of João V (John V, 1706-1750), known as "the Magnanimous," a period of immense wealth and power for Portugal, largely funded by Brazilian gold. Struck at the Portuguese colonial mint in Goa, India, for circulation in Mozambique, this coin exemplifies the intricate logistical and administrative networks of the Portuguese Empire. As KM#1 for Mozambique, it represents a foundational element of the region's early numismatic history, providing essential small denomination currency for daily commerce within the vast colonial territories of Portuguese East Africa.

Artistry: The design of this colonial copper issue, while not attributed to a specific engraver, reflects the practical aesthetic prevalent in Portuguese overseas mints. Unlike the elaborate Baroque coinage of the metropolis, colonial copper prioritized legibility and durability. It typically features the crowned royal monogram of João V, often stylized as "J5," on the obverse, symbolizing imperial authority. The reverse commonly displays a large cross, frequently the Cross of the Order of Christ, a powerful emblem of Portuguese expansion. The stylistic school is utilitarian Baroque, adapted for mass production and colonial necessity.

Technical/Grading: Weighing 12 grams and measuring 26 millimeters, this 10 Réis is a substantial copper coin. For grading, key high-points to examine for wear include the crown atop the royal monogram and the extremities of the cross. Given the manufacturing techniques of the 18th century and the nature of colonial production, strike quality can vary considerably. Collectors should anticipate potential planchet imperfections, such as laminations or porosity, and occasional off-center strikes or areas of weakness, particularly in the finer details of the monogram or legend. A strong strike will exhibit sharp, complete elements.
