1921 Portugal First Republic Coat of Arms 5 Centavos Bronze Coin – NGC MS63 RB Highlights: 1. The prominent armillary sphere on the obverse directly links Portugal’s glorious Age of Discoveries (maritime exploration heritage) with the new republican ideals after the 1910 revolution. It replaced royal imagery, making this coin a tangible artifact of political regime change — a unique historical narrative not found in most other contemporary European minor coins. 2. This belongs to a brief 3-year type (1920–1922) of bronze small change before design modifications in 1924. Combined with the relatively high mintage but challenging survival in high-grade red-brown condition, it offers an accessible yet satisfying “type coin” challenge for First Republic specialists, especially preserved with attractive original mint luster. 3. In MS63 RB, it provides strong visual appeal (remaining red copper glow mixed with brown toning and cartwheel luster) at a modest price point. It serves as an ideal, budget-friendly certified example for building a thematic collection of 20th-century European republican coinage or world bronze minors, while NGC certification adds security and display value without the high cost of true key dates. Coin Story: In October 1910, the Portuguese Republican Revolution overthrew the Braganza dynasty and established the First Portuguese Republic. The new regime urgently needed to reform the currency system. In 1911, the Escudo was introduced as the new monetary unit (1 Escudo = 100 Centavos), replacing the old Real system. Between 1920 and 1922, the Republic issued a series of bronze/copper small-denomination coins (1, 2, and 5 Centavos) to meet everyday low-value transaction needs. The 1921 5 Centavos features the national coat of arms design: Obverse: The Portuguese Republic coat of arms, with the armillary sphere (armillary sphere) above the shield — symbolizing Portugal’s Age of Discoveries and maritime heritage — surrounded by “REPÚBLICA PORTUGUESA” and the date 1921 below. Designed by Domingos Alves do Rego. Reverse: Large numeral “5” in the center, “CENTAVOS” above, with shield elements or simple decorations below, and a beaded border. This coin embodies the Republic’s symbolism: the armillary sphere represents Portugal’s seafaring imperial legacy and republican ideals, replacing royal portraits or emblems from the monarchy era. It belongs to the transitional small-change coinage of 1917–1922, reflecting the economic turmoil (inflation and political instability) of the young Republic. Small copper coins became the primary medium for daily payments. From 1924 onward, the design style was adjusted, making this series a classic representative of First Republic coinage.
