40 Reis - João VI Lisboa mint

Historical Context: The 1825 40 Reis copper coin was issued under João VI, King of Portugal. This era saw significant imperial upheaval, including the Napoleonic Wars' aftermath and Brazil's independence recognition in 1825. Its issuance for São Tomé and Príncipe highlights Portugal's efforts to maintain economic and administrative authority within its African colonies during a period of imperial contraction and domestic political challenges.

Artistry: While the specific engraver is undocumented, the dies for this colonial issue originated from the Lisbon Mint, embodying neoclassical stylistic conventions of early 19th-century European coinage. The obverse typically presents a laureate bust of King João VI, often facing right, rendered with a dignified royal portrait. The reverse commonly features the crowned Portuguese coat of arms (shield with five escutcheons and seven castles), above the "40 REIS" denomination, within a legend denoting the monarch and date.

Technical/Grading: As a copper coin for colonial circulation, this 40 Reis frequently displays characteristics inherent to its metal and purpose. Key high-points for wear on the obverse include the king's hair, laurel wreath, and shoulder. On the reverse, the crown's intricate details and central elements of the Portuguese shield are most prone to flattening. Examples often show surface imperfections, planchet flaws, and varied patination due to copper's nature and tropical usage. A complete, sharp strike is rare; central weakness is commonly observed.
