12800 Réis - João V 1st Type of Shield, Bahia Mint

Historical Context: This impressive 12800 Réis coin, struck between 1727 and 1729 at the Bahia Mint, represents the zenith of Brazil's colonial gold production under King João V of Portugal. Known as "The Magnanimous," João V's reign (1706-1750) was largely financed by the vast gold and diamond discoveries in Brazil, transforming Portugal into one of Europe's wealthiest nations. The 12800 Réis, a significant gold denomination, played a crucial role in international commerce and served as a tangible symbol of the immense wealth flowing from the colony to the metropole, solidifying Portugal's imperial power.

Artistry: The design of this 12800 Réis coin adheres to the Baroque aesthetic prevalent in European monarchical coinage of the era, characterized by its grandeur and detailed execution. While specific engravers for colonial Brazilian issues are often unrecorded, the style reflects the influence of Portuguese royal mint traditions. The obverse features the crowned Portuguese royal arms, specifically noted as the "1st Type of Shield," indicating particular heraldic details or shield shape used early in João V's coinage. The reverse prominently displays the armillary sphere, a potent symbol of Portuguese maritime exploration and global empire, accompanied by the date and mintmark.

Technical/Grading: Struck in .917 fine gold, the substantial weight of 28.68 grams and large diameter of 36 millimeters presented considerable challenges for consistent striking. High points susceptible to wear or weakness typically include the crown's uppermost elements and the intricate details within the royal shield on the obverse. On the reverse, the raised bands and central globe of the armillary sphere are often the first areas to show flattening. Due to the hand-fed presses and the metal's relative softness, these coins frequently exhibit variable strike quality, with central weakness or minor planchet irregularities being common characteristics of the series.
