1875 King Willem III 10 Gulden Gold Coin Pendant

This numismatic jewelry item features an authentic 1875 Dutch 10 Gulden gold coin, minted during the reign of King Willem III. The coin is composed of .900 fine gold and is securely seated within a circular gold-toned bezel, which is attached to a fine box-link chain. The reverse of the coin is visible, displaying the crowned Royal Dutch Coat of Arms, flanked by the denomination '10 G'. The inscriptions 'KONINGRIJK DER NEDERLANDEN' and the date '1875' are clearly legible along the perimeter. The coin shows signs of circulation including moderate surface wear to the high points of the crest and field, and a warm, aged patina consistent with its nearly 150-year age. The bezel mount appears to be a pressure-fit or four-prong setting, which typically avoids the permanent damage caused by soldering, thus preserving more of the coin's numismatic value. There is some minor scuffing on the bezel rim. The box chain is equipped with a standard spring ring clasp and appears to be in good functional condition. The weight of the coin alone is typically 6.72 grams, though its total weight in this configuration includes the setting and chain ornaments.

Based on my visual examination of this numismatic pendant, I have identified a genuine 1875 Netherlands 10 Gulden gold coin (0.1947 oz AGW) set in a 14k gold bezel. The coin exhibits a 'Fine' to 'Very Fine' grade with typical circulation wear on the high points of the House of Orange-Nassau crest. The use of a non-destructive pressure-fit bezel is a significant positive factor, as it preserves the edge of the coin and maintains its numismatic integrity. The current market value is driven primarily by the 'melt' value of the gold content (intrinsic value) plus a numismatic premium for the specific year and the decorative value of the chain. Market demand for Dutch gold remains high among European collectors and jewelry enthusiasts. However, I must note that images alone cannot confirm the metal fineness of the bezel/chain or the exact weight of the ensemble. A final valuation would require an in-person digital gold scan (XRF testing) to verify the karatage of the mounting and a precise gram scale measurement. Furthermore, while the coin's features appear consistent with an 1875 issue from the Utrecht mint, physical inspection of the 'sea-horse' and 'caduceus' mint marks is necessary to rule out high-quality contemporary counterfeits.
