A certified 1712 Spanish gold 8 escudo cob doubloon — minted in Lima under King Felipe V with assayer initial M and recovered from the 1715 Plate Fleet wreck off the east coast of Florida — is set in an 18K yellow gold diamond-accented pendant signed "SS," suspended on an 18K yellow gold Byzantine chain, totaling 93 grams with a chain length of 14.5 inches. Accompanied by Smith's Certificate of Authenticity and Registration No. NP***.

The 1715 Plate Fleet was a convoy of eleven Spanish treasure ships carrying the accumulated wealth of the Americas back to Spain when they were destroyed by a catastrophic hurricane on July 31, 1715, off the east coast of Florida near present-day Vero Beach — one of the most dramatic and historically significant maritime disasters in the history of the New World. The fleet carried millions of pesos worth of gold and silver coins, jewelry, and trade goods belonging to the Spanish Crown and private merchants, nearly all of which sank to the ocean floor where it remained for over two centuries before salvage operations beginning in the 1960s began recovering individual coins and artifacts. Coins recovered from the 1715 Fleet are among the most historically significant and collectible numismatic treasures in the world, representing physical artifacts from one of history's most dramatic events at the intersection of empire, commerce, and natural disaster. The 8 escudo denomination — the largest gold coin minted by the Spanish Empire and commonly called a "doubloon" — was the highest-value coin produced at the Lima mint and was reserved for the most substantial financial transactions of the colonial era.

This particular 8 escudo doubloon is described in its Smiths certificate as a superb, well-centered and detailed example featuring the full date (1712), mintmark L (Lima), denomination (8), and assayer's initial M — a combination of legibility and completeness that places it among the finest documented examples from the 1715 Fleet wreck. The obverse displays the crowned royal arms of Spain with the cross of Jerusalem, while the reverse shows the crowned Hapsburg shield with lions and castles in the four quadrants — both sides showing the bold, hand-struck character unique to cob coinage. The 18K yellow gold pendant mounting features four diamond-set cross tabs that grip the coin at the cardinal points without covering its faces, while the diamond-pave bail above is marked with the "SS" maker's signature of the pendant craftsman. The 18K Byzantine chain provides a strong, flexible, and visually substantial support for a pendant of this weight and historical significance.
