Description
This is a large-format 1 Piso coin from the Philippines, featuring the iconic profile of national hero Jose Rizal. Part of the 'Pilipino Series' which replaced the English-language 'Filipino Series', it represents a move toward nationalistic branding on currency. While it resembles silver to the untrained eye, it is composed of cupronickel, a standard base metal alloy for high-denomination circulation coins of the 20th century.
Key Features
Distinctive large 33mm diameter; 'PISO' spelled in Tagalog rather than 'PESO'; Jose Rizal portrait.

Business strike with a matte/circulated finish. Features a left-profile bust of Jose Rizal, the national hero of the Philippines. Beaded border design.
Hallmarks & Stamps
Obverse: '1 PISO', 'JOSE RIZAL'. Reverse (not visible): 'REPUBLIKA NG PILIPINAS' and the Coat of Arms of the Philippines.
Construction Details
Die-struck from nickel-plated or solid copper-nickel planchets. Industrial machine-milled fabrication.
Functional Features
Milled/reeded edge to prevent debasement; legal tender for one Peso in the Philippines during its circulation period.
Handle & Grip Details
None (standard numismatic item).
Craftsmanship Details
Standard mass-produced circulating coinage. Good die relief and clear lettering, typical of mid-20th-century industrial minting.
Authentication Indicators
Correct font style for the 'PISO' text; authentic portrait features of Rizal consistent with Central Bank dies; absence of silver hallmark '925' or 'Sterling' as this is base metal currency.
Origin & Manufacturing
Philippines; specifically the Central Bank of the Philippines, though planchets and striking were often contracted to foreign mints like the Royal Mint or Sherritt Mint during the early 70s.
Era & Period
Pilipino Series (1972-1974) / Ang Bagong Lipunan Series transition.
Age Estimate
Circa 1972-1974 based on the 'PISO' denomination and Jose Rizal portrait style.
Cultural Significance
Represents the post-colonial transition of Philippine currency into the national language (Tagalog) and celebrates the intellectual foundation of Philippine independence.
Condition Notes
Very Fine (VF) to Extremely Fine (EF). Visible circulation wear on the high points of Rizal's hair and cheek. Minor surface scratches and toning typical of copper-nickel alloys.
Value Estimate
$0.50 - $2.00 USD. These are very common and hold primarily sentimental or historical value rather than precious metal or high numismatic value.
Care & Maintenance
Avoid cleaning or polishing with abrasives, as this destroys numismatic value. Store in a PVC-free coin flip or cardboard holder to prevent 'green slime' (plasticizer damage).
