Type
Coin/Bullion
Maker
United States Mint (Philadelphia) for the Central Bank of the Philippines. These were struck under contract during a period of transition in Philippine monetary history.
Material
Cupro-Nickel (75% Copper, 25% Nickel). Note: These specific post-1958 coins do not contain silver, unlike the earlier US-Philippine pesos which were .750 or .800 fine silver.
Dimensions
Variable by denomination; 50 Centavos is 30mm (approx. 10g), 25 Centavos is 23.5mm, 10 Centavos is 17.5mm.
Description
A collection of mid-20th century Philippine circulation coins. While they possess a 'silver' appearance typical of nickel-based alloys, these pieces represent the shift away from precious metal coinage toward industrial metals for everyday use. They feature prominent Philippine iconography including the national shield and profiles of revolutionary figures.
Key Features
Presence of the 'English' legends (instead of the later Tagalog 'Sari-saring Barya'), high relief of the national coat of arms, and the distinctive cupro-nickel luster which differs from the warmer tone of authentic silver.
Material & Composition
Cupro-Nickel (75% Copper, 25% Nickel). Note: These specific post-1958 coins do not contain silver, unlike the earlier US-Philippine pesos which were .750 or .800 fine silver.
Finish & Decoration
Business strike finish with frosted relief and satin fields. Features the coat of arms of the Republic of the Philippines on the obverse and portraits of national heroes like Marcelo H. del Pilar (50 Centavos) or Lady Liberty/Vulcan (older motifs) on reverse.
Hallmarks & Stamps
Stamped with 'CENTRAL BANK OF THE PHILIPPINES' and 'REPUBLIC OF THE PHILIPPINES'. Some may bear a small 'P' mint mark for Philadelphia or no mark at all.
Construction Details
Die-struck/machine-minted using high-pressure steam or electric presses. Reeded edges for higher denominations to prevent clipping.
Functional Features
Standardized currency for commerce; reeded edges to provide tactile identification and security against tampering.
Handle & Grip Details
Not applicable (coinage form factor).
Craftsmanship Details
Precision industrial minting; sharp detail on the central shield and clear, legible typography consistent with mid-century US Mint quality standards.
Authentication Indicators
Authentic government-issued currency. Design matches known US Mint strikes for the Philippines. Lacks the hallmark '925' or 'Sterling' because it is base metal coinage.
Origin & Manufacturing
United States (Philadelphia Mint) and Philippines (Manila). Struck under the authority of the Central Bank of the Philippines.
Era & Period
Modern Republic Era (English Series, 1958–1967). This period followed the post-WWII US administration and preceded the Pilipino Series (Tagalog).
Age Estimate
Circa 1958-1966 based on visible dates such as 1964 and 1966 on the coin faces.
Cultural Significance
Represents the economic recovery and sovereign identity of the Philippines in the decades following World War II and its independence from US administration.
Condition Notes
Circulated (Fine to Very Fine). Visible surface scratches, rim dings, and 'bag marks' from contact with other coins. Moderate oxidation but no significant corrosion.
Value Estimate
$0.50 to $5.00 USD per coin depending on denomination and exact condition. Primarily of historical and numismatic interest rather than bullion value.
Care & Maintenance
Do not clean with abrasives or silver polish as these are not silver; store in a cool, dry place. For numismatic value, avoid 'dipping' in acids which can strip the original mint luster.
Similar Pieces

Interesting Facts
The 1958-1966 English series was the last Philippine series to be inscribed entirely in English. Many people mistake these for silver because previous Philippine Centavo issues (before 1945) were indeed made of high-purity silver.
