Represents the Philippines' commitment to highlighting native biodiversity and modernization of their financial infrastructure through the NGC series.
Condition Notes
Very Good/Circulated. Visible surface contact marks (bag marks) and minor scratches consistent with circulation in commerce.
Value Estimate
Face value: 0.25 Philippine Pesos (approx $0.004 USD). Numismatic value: Minimal, usually found in bulk lots unless in high-grade 'Uncirculated' condition.
Care & Maintenance
No specialized silver cleaning is required as it is not silver. Keep dry to prevent oxidation of the steel core if the plating is breached. Avoid abrasive cleaners that can strip the nickel layer.
