Old Dutch Coin Appraisal

Dutch 50 Cents Coin (Square, Wilhelmina)

This appears to be a square-shaped 50 cent coin from the Netherlands, likely minted during the reign of Queen Wilhelmina (1890-1948). The coin is made of a dark-toned metallic material, possibly a copper-nickel or silver alloy that has developed a dark patina over time. Its distinctive square shape with rounded corners is a notable physical characteristic. The obverse side, visible in the image, clearly displays the denomination "50 C." in a geometric, Art Deco-inspired font. Surrounding the denomination, there are stylized patterns of interconnected lines and possibly triangles, which are characteristic of Dutch coinage from this period, particularly those designed by J.J. van Goor. The surface shows considerable wear consistent with circulation, indicated by softened details and some apparent scratching or rub marks, especially towards the edges and within the design elements. There are no obvious signs of significant damage like deep gouges or repairs, but the overall patina suggests age and handling. The edges appear slightly raised, forming a thin border around the central design. This square coin is known for its unique aesthetic and represents a specific period in Dutch numismatic history.
