5 Zlotys Polonia, Trial Strike B

The "Polonia" 5 Złotych was part of an ambitious interwar reform of Polish coinage under the Second Republic, with multiple compositional trials struck before the silver standard issue was finalized. Trial Strike B in bronze was never intended for circulation — it exists as a production test, almost certainly struck in very limited numbers at the Warsaw Mint. The silver production version saw a mintage of roughly 1,100,000 pieces in 1933 and 1934 combined, making the bronze trial a genuinely rare document of the minting decision process.
