| Reverse description | The denomination numeral '5' appears prominently at the top of the field, followed below by the word 'GROSZY' in large capital letters spanning the width of the coin. Below this, the four-digit date '1811' is struck in bold numerals, and beneath the date the mintmaster's initials 'I.B.' are placed centrally, identifying the Warsaw mint official Jan Baptist Menadier. The reverse carries no peripheral legend, presenting a clean, typographic design typical of early nineteenth-century Polish subsidiary coinage. |

| Additional information |
The Duchy of Warsaw was a French client state carved out of Prussian and Austrian partition territories following Napoleon's victories at Jena and Austerlitz, and its coinage was issued under Frederick Augustus I of Saxony, who held the title of Duke by Napoleon's direct appointment. The mint mark I.B. identifies the Warsaw engraver and mintmaster Jan Beyer, who oversaw production during the duchy's short-lived existence.
The duchy itself collapsed after Napoleon's Russian disaster in 1812, absorbed into Russian-controlled Congress Poland by 1815. Coins struck in the final year of this issue were circulating in a political entity that had, in practical terms, already ceased to function.
