| 背面描述 | The large numeral 5 dominates the upper central field, with the denomination inscription GROSZY curved beneath it in bold relief. To the left, a tied spray of stylised oak or grain leaves rises diagonally, bound at its base with a ribbon bow, serving as the principal decorative device. The word PRÓBA appears to the right of the numeral 5, identifying this piece as a trial strike. The field is otherwise plain, with no additional border ornamentation. |
