Material & Composition
Nickel-Brass (70% copper, 5.5% nickel, 24.5% zinc). This item is not silver; however, its pale golden/silvery hue under certain lighting often leads to confusion with silver coinage or cupro-nickel alloys.
Finish & Decoration
Standard circulation strike with a matte field and raised (relief) elements. The obverse features the profile portrait of Emilio Aguinaldo, the first President of the Philippines, with a scalloped inner border and 'REPUBLIKA NG PILIPINAS'.
Hallmarks & Stamps
The coin features the mint mark of the Bangko Sentral ng Pilipinas (a stylized BSP logo) notably absent on this specific year for some mintages or located on the reverse. Date stamp '2005' on the obverse.
Construction Details
Machine-struck/Die-struck on a solid nickel-brass planchet. The edge is reedable (milled), though often worn smooth in circulation examples.
Functional Features
Monetary currency. It includes tactile elements (the scalloped border) to assist visually impaired users in distinguishing it from other denominations.
Handle & Grip Details
Not applicable (coinage). The edge features a continuous reeding to prevent 'clipping' or shaving of the metal and to provide grip during handling.
Craftsmanship Details
Standard industrial minting. The relief is shallow to ensure stackability and durability in circulation. The letter spacing and alignment are characteristic of high-volume government minting.
Authentication Indicators
The weight, diameter, and distinctive 'PISO' typeface are consistent with BSP standards for the 2005 mintage. The wear pattern is consistent with nickel-brass alloy rather than plated steel.
Origin & Manufacturing
Quezon City, Philippines. Manufactured by the Bangko Sentral ng Pilipinas Security Plant Complex using industrial coin presses.
Era & Period
Contemporary/Modern Republic of the Philippines. Specifically the 1995-series mintage that remained the standard for over two decades.
Age Estimate
Dated 2005; 19 years old at the time of this analysis.
Cultural Significance
Emilio Aguinaldo's presence on the coin honors the country's struggle for independence. The 5-piso coin was a workhorse of Philippine commerce, essential for 'Jeepney' fares and 'Sari-sari' store transactions.
Condition Notes
Good to Very Good (Circulated). Visible surface scratches (bag marks), minor rim dings, and significant oxidation/patina covering the original luster. The 'REPUBLIKA' lettering shows wear consistent with nearly 20 years of use.
Value Estimate
Face value is 5 Philippine Pesos (approx. $0.09 USD). In numismatic markets, a circulated 2005 specimen typically sells for $0.25 to $1.00 USD, though uncirculated (MS) examples can fetch slightly more.
Care & Maintenance
For circulation coins, cleaning is generally discouraged as it can ruin numismatic value. Store in a dry, PVC-free coin flip if keeping for a collection. Do not use silver polish, as this is a brass alloy.
Similar Pieces
Often confused with the newer 2018 5-Piso (which is silver-colored) or the 10-Piso bi-metallic coin of the same era. Collector versions exist in proof sets with higher luster.
Interesting Facts
This specific series was replaced in 2018 by the New Generation Currency (NGC) series, which made the 5-piso coin smaller, silver in color (nickel-plated steel), and featured Andres Bonifacio instead of Aguinaldo.
