Hallmarks & Stamps
Mint mark 'MW' (Mennica Warszawska) found on the obverse under the eagle's right claw. Purity marks are absent as it is base metal currency.
Construction Details
Machine-struck using hardened steel dies and high-pressure industrial presses. Modern mass-production minting technology.
Functional Features
Reeded (serrated) edge for tactile identification and to prevent clipping. Circular planchet shape.
Handle & Grip Details
N/A (Numismatic object)
Craftsmanship Details
Precision industrial striking. The relief is uniform and the alignment (medal alignment) is precise, reflecting high-quality modern technical minting standards.
Authentication Indicators
Design matches official National Bank of Poland (NBP) specifications. Die-striking is crisp, consistent with Warsaw Mint standards. Lack of 'silver' hallmarks confirms it is a standard base-metal issue.
Origin & Manufacturing
Warsaw, Poland; minted at the Warsaw Mint (Mennica Polska).
Era & Period
Third Republic of Poland (Modern Era, 1989-Present). This specific design was introduced following the 1995 currency re-denomination.
Age Estimate
Modern (Post-1995). Without seeing the obverse date, it is likely from a production run between 1990 and the present year.
Cultural Significance
Represents the economic stabilization and Western alignment of post-communist Poland. It is a daily-use object for millions of Polish citizens.
Condition Notes
Circulated condition. Visible surface 'bag marks' (tiny nicks from other coins), light scratches, and general handling wear. No significant oxidation or corrosion visible. Overall: Very Good (Circulated).
Value Estimate
Face value: 0.50 PLN (approx. $0.12 USD). Collector value for common dates in circulated condition is negligible. High-grade uncirculated examples may sell for $1.00-$2.00.
Care & Maintenance
No special care required. If collected for numismatic value, do not polish or clean with abrasives as this destroys market value. Store in a PVC-free coin flip or capsule to prevent environment-related spotting.
Similar Pieces
Polish 10 Groszy and 20 Groszy coins (smaller, same metal). Older Polish silver coins (pre-1939) such as the Jan Kazimierz or Jadwiga issues, which do contain actual .750 or .900 silver.
Interesting Facts
The Grosz (plural: grosze or groszy) has been a Polish unit of currency since the 14th century, originally inspired by the Bohemian 'Grossus'. This modern version was part of the 1995 reform that 'slashed four zeros' from the old currency.
