Historical Context
The 50 centavos coin issued in 1968 in Portugal is part of the third series of half-escudo (50 centavos) coins of the Portuguese Republic, which started in 1927.
This series (1927–1968) was minted in nickel silver (Alpaca alloy), approximately composed of 61% copper, 20% zinc, and 19% nickel.
On the obverse (front) is an allegory of the Republic, wearing a Phrygian cap and facing right, with the inscription REPUBLICA PORTUGUESA and the date “1968.” The reverse shows the denomination “50 CENTAVOS” below the national shield and decorative elements.
The 1968 mintage was 11,448,000 pieces. These coins circulated until they were formally withdrawn, replaced by other denominations as the currency evolved.

Collector Notes
- Although the mintage is relatively high (~11.4 million), being the last year of the series gives it extra interest for collectors aiming to complete annual sets.
- Condition is critical: coins graded Fine (F), Very Fine (VF), Extremely Fine (XF), or Uncirculated (UNC) can vary significantly in value.
- Check for excessive wear, deep scratches, or improper cleaning, as these factors greatly reduce market value.
Numismatic Value
- According to catalogs, circulated coins are worth around €0.56.
- Coins in “Extremely Fine” or “Uncirculated” condition typically sell for €2–5, depending on the seller and preservation.
- In specialty numismatic shops, coins in near-perfect condition may list slightly higher, but this coin is not considered rare, so its financial value is modest.
Conclusion
For collectors of Portuguese coins, the 1968 50 centavos is an interesting piece as the final year of its series, with well-documented specifications and a relatively high mintage. From an investment perspective, its value is low, except for coins in exceptional condition (UNC) sought after by specific collectors.
