Dukat koronny - Stanisław August Poniatowski

The reference codes here tell a story of their own: Kopicki assigns no number, placing this piece outside his standard sequence — a strong indicator of a pattern or probe issue rather than a coin struck for general circulation. The ParM#1275 attribution situates it within Plage and Mańkowski's documentation of Polish medallic and pattern coinage from the Poniatowski reign, a period when the Royal Mint in Warsaw was simultaneously navigating monetary reform pressures and the political collapse that would culminate in the First Partition's aftermath.

The PN113 designation in KM confirms proof or pattern status. Silver at this weight and diameter was an unusual choice for a ducat denomination, which conventionally ran in gold.
