The 1 centavo coin from 1921 belongs to an interesting period of Portuguese monetary history. It was minted during the First Republic, a politically turbulent era marked by economic reforms. Although it has a low face value, this coin attracts collectors due to its relative scarcity and the limited circulation of coins from this series.
Historical context
After the establishment of the Republic in 1910, Portugal adopted a new monetary system that reorganized the escudo and its subdivisions. Bronze coins of 1, 2, 5, and 10 centavos became part of everyday transactions.
The year 1921, however, was one of the most unstable in terms of regular production. Political turmoil, inflation, and frequent changes in government policies caused some issues to have lower mintages or limited distribution, which increased the numismatic interest of certain dates.
Technical characteristics
The 1921 1 centavo coin features the typical characteristics of the Republican bronze series.
Specifications:
- Face value: 1 centavo
- Composition: Bronze
- Weight: approximately 1.0 g
- Diameter: about 15 mm
- Edge: plain
- Obverse: inscription República Portuguesa and the national coat of arms.
- Reverse: numeral 1 in the center, surrounded by the word Centavo and the date 1921.
The design is simple and functional, reflecting the economical style of the period.
Mintage
Exact mintage numbers vary depending on the source, but experts consider the 1921 issue relatively less common when compared to other years in the same series. This plays a direct role in its market value.
Numismatic value
The value of the coin depends on three main factors:
- Relative rarity of the year
- State of preservation
- Collector demand
Here is a realistic estimate for the current market:
- Circulated (low grade): 1 to 3 euros
- Well preserved (VF to XF): 5 to 15 euros
- Almost uncirculated (AU): 20 to 35 euros
- Uncirculated (UNC): can exceed 40 to 60 euros, depending on the level of perfection and demand.
Coins certified by services such as NGC or PCGS may reach higher values, especially when graded above MS63.
Why collectors value this coin
- It represents the early Republican period.
- Some dates in this series are harder to find in good condition.
- It’s an excellent entry point for collectors of Portuguese numismatics.
- Small bronze coins tend to wear down more easily, making high-grade pieces more desirable.
Conclusion
The 1921 1 centavo coin may look small and simple, but it carries an important piece of Portugal’s economic history. For collectors, it combines accessibility with historical interest, and in well-preserved condition it can reach respectable numismatic values.
