Spanish Colonial Silver Cob Coin with Certification of Historic Artifact

This item consists of a hand-struck Spanish Colonial silver cob coin, identified by the accompanying documentation as a 4 Reale Piece of Eight. The coin features an irregular, or 'cob' shape, which was typical of silver struck at New World mints such as Lima or Potosi during the 16th to 18th centuries. It displays a visible patina and surface wear consistent with age and potential maritime salvage history. Accompanying the coin is a 'Certification of Historic Artifact' issued by the Conch Coin Company, dated July 16, 1992. The certificate lists the artifact number as 1785 and specifies a weight of 12.3 grams with a grade of 'Fine'. The documentation includes a black display mount with the artifact number printed in white, along with a protective plastic sleeve holding a descriptive tag. The certificate is printed on parchment-style paper featuring illustrations of Spanish galleons and Gothic-style typography. The overall condition of the documentation shows minor handling wear, while the coin itself exhibits expected rounded edges and partial strike details inherent to the cob production process.
