Brief Description

This coin is part of the 'Flora and Fauna Series' issued by the Central Bank of the Philippines starting in 1983, designed to highlight the country's national heroes alongside its biological diversity.
Estimated Value
$0.10-$0.50 in circulated condition; $1.00-$3.00 in uncirculated condition.
Care Instructions
Handle by the edges to avoid transferring skin oils. Store in a cool, dry place within a PVC-free flip or capsule. Do not clean with chemicals or abrasives.
Mint Mark
Contains the BSP (Bangko Sentral ng Pilipinas) mint mark on the obverse to the left of the bust.
Mintage & Rarity
Common; high mintage typical for standard circulation coinage of that era.
Weight & Diameter
3.85g weight, 21.0mm diameter
Edge
Reeded
Apparent Grade
Fine to Very Fine. The coin shows significant surface wear, darkening (toning), and minor surface scratches.
Obverse (Front)
Features the head of Juan Luna facing right, a renowned Filipino painter and political activist. The legend reads 'REPUBLIKA NG PILIPINAS' with the year '1988' at the bottom.
Reverse (Back)
Features a Graphium idaeoides (Butterfly). Above it is the denomination '25 SENTIMO'. Underneath is the scientific name of the butterfly.
What Drives This Coin's Value
Condition is the primary factor. These are very common in circulated grades; only high-grade Mint State examples carry a premium.
Similar Coins
Easily confused with other denominations from the same 'Flora and Fauna' series, such as the 50 Sentimo or 1 Piso, though the size and specific 'butterfly' reverse distinguish it.
Authenticity & Counterfeit Red Flags
Authentic coins will have sharp reeding on the edge and clear, though potentially worn, lettering. Weight should align closely with the 3.85g spec.
Notable Varieties & Errors
Minor die rotations or strike errors exist but carry little premium unless extreme.
