History and Context
The 1957 50 centavos coin belongs to the period of the Cruzeiro (First Cruzeiro), when Brazil used this currency. This 50-centavos series was minted between 1957 and 1961, according to numismatic catalogs.
The Cruzeiro, at that time, was part of a transitional economic phase in Brazil, with inflation and changes in the monetary system, which created the need for fractional coins for daily use.
Technical Specifications
Key physical characteristics of the 1957 50 centavos coin:
- Composition: Aluminum (~99.5%)
- Weight: Approximately 1.83 g
- Diameter: About 21.07 mm
- Thickness: Around 1.97 mm
- Edge: Smooth (no reeding)

The obverse features the national coat of arms: a star surrounded by 27 smaller stars (representing the states) with the Southern Cross inside, flanked by tobacco and coffee branches.
The reverse shows the denomination “50 CENTAVOS” above a line, with the date “1957” below.
This coin was minted by the Casa da Moeda do Brasil in Rio de Janeiro and was demonetized on December 1, 1964.
Mintage
The 1957 coin had a relatively high mintage: 49,350,000 coins were produced.
This large number means the coin is not particularly rare, as many circulated.
Variants and Errors
Although considered a common coin, some variants and minting errors exist:
- Weak strike: One of the most frequently reported anomalies for the 1957 version. This is relatively common, which limits its added value.
- Decentralized strike (“boné”): Some coins show misaligned strikes.
- Reversed horizontal variant (MA-10): A specific variant described by collectors with the reverse slightly shifted.
These variants can increase collector interest, especially for those seeking minting errors or less common editions.
Numismatic Value
The coin’s value depends heavily on its condition and whether it has any error or variant:
- Common examples:
- Users report values between $0.26 and $0.63 USD for circulated to uncirculated coins.
- Brazilian numismatic shops offer them from around R$3.00 to R$6.50 for standard circulated coins.
- Coins with variants or errors:
- The MA-10 variant can sell for R$70.00, much higher due to its rarity.
- Even common errors like weak strikes generally command modest prices, as they are relatively frequent.
- International market:
- Typical listings on eBay show prices ranging from €7.95 to €10.95 depending on condition.
These prices indicate that the coin is generally affordable for collectors, except for rare variants.
Importance for Collectors
- Despite its high mintage, the 1957 50 centavos coin is interesting for completing Cruzeiro series for Brazilian collectors.
- Minting variations (like weak strikes or the “boné” error) appeal to collectors of errors, adding value to well-preserved specimens.
- Since it is made of aluminum, its intrinsic material value is very low; the value is mainly numismatic, based on rarity or variant.
Conclusion
The 1957 50 centavos coin from Brazil is a relatively common coin with a high mintage, made of lightweight aluminum, and circulated during the First Cruzeiro period. Its face value is obsolete, but for collectors, it has appeal for completing series, for Brazilian monetary history, and for its minting variants.
Most circulated coins have low numismatic value—just a few dozen reais in Brazil or a few euros internationally. Rare variants or errors, however, can significantly increase its value depending on rarity and condition.
