The sculpture is a detailed engraving on a round coin. The central design depicts a landscape with bridges, cityscape elements, and a field of stars above. Surrounding the scene, the upper portion of the coin features a floral and heraldic embellishment with a shield-like shape at the center. The coin is made of a dark metallic material, likely bronze or copper, with a rich brown color and patina. The outer edge of the coin includes an inscription in Latin characters. The sculpture shows intricate details that suggest careful and precise workmanship commonly seen in ceremonial or commemorative medallions.
