This exquisite pendant features a sea-salvaged 1/2 reales silver cob coin from the Spanish Empire, discovered near the Peruvian coast, likely from a shipwreck near Callao. Minted in the 1700s, the coin displays castles and lions in the quarters of a cross, with the royal monogram of Spain. Set in a handcrafted 18k gold pendant, it weighs 2.9 grams and measures 16 x 21 mm, including the pendant loop. Authenticity guaranteed, this rare piece of history is ideal for collectors or as a standout piece of jewelry.
