Construction Details
Machine-struck/Die-struck on a planar metal blank (planchet) under high pressure using industrial hydraulic minting presses.
Functional Features
Standard legal tender currency; features a reeded (milled) edge to prevent clipping and provide tactile grip.
Handle & Grip Details
Not applicable (coinage). The milled edge serves as the primary tactile interface for the user.
Craftsmanship Details
Industrial mass-production. High-quality die-sinkery is evident in the sharp serifs of the font and the intricate detailing of the oak leaves.
Authentication Indicators
Alignment of the wreath, crispness of the '10' relief, and standard cupronickel luster. Lack of silver hallmarks is consistent with modern circulation denominations.
Origin & Manufacturing
Warsaw, Poland. Manufactured by the Mint of Poland under the authority of the National Bank of Poland (NBP).
Era & Period
Third Republic of Poland, contemporary era (1995-present). Designed during the transition to a modern market economy.
Age Estimate
Issued between 1990 and 2023. The specific design was introduced in 1995 after the 10,000 to 1 currency redenomination.
Cultural Significance
Represents the post-Communist economic stability of Poland and the successful reintroduction of the Złoty currency system following hyperinflation.
Condition Notes
Circulated condition with visible surface 'bag marks', light scratches, and some localized oxidation/dirt in the crevices of the lettering. Grade: Very Fine (VF).

Face value is 0.10 PLN (approx. $0.025 USD). Numismatic value for a circulated specimen is negligible, though uncirculated 'Mint State' examples may carry slight premiums.
