Cartagena, Colombia – Newly analyzed gold coins, salvaged from the depths off the Colombian coast, have officially been identified as cargo from the legendary San José galleon. This “world’s richest shipwreck” met its fate in 1708 during a fierce naval battle with British warships.

The San José was carrying an estimated 200 tons of gold, silver and emeralds when it sank. The current estimated value could reach a staggering $17 billion, sparking intense interest and legal battles over its recovery.

Confirmation of San José Origin

A recent study in the journal Antiquity, led by researchers from the Colombian Navy and other national authorities, provides definitive proof. Detailed images taken by remotely operated vehicles (Rovs) of the scattered coins at a depth of approximately 1,970 feet (600 meters) were crucial to the analysis.

The Colombian government initially announced the wreck’s location in 2015, after which deep-sea observations occurred via ROV expeditions in 2021 and 2022. Their research unequivocally links the coins and surrounding debris to the San José’s tragic 1708 sinking.

Did You Know? The san José’s treasure could potentially fund numerous social programs in Colombia, but legal challenges and preservation concerns complicate the situation.

Decoding the Sunken Gold

Researchers documented dozens of the rough gold coins scattered within the shipwreck. Though the exact count remains unknown, the high-definition photographs allowed meticulous examination. The coins averaged 1.3 inches (32.5 millimeters) in diameter and weighed approximately 27 grams (about 1 ounce).

Coin designs feature variations of the Jerusalem cross alongside shields displaying castles and lions. The reverse side depicts the “Crowned Pillars of Hercules above the waves,” a unique identifier of the Lima Mint.

Notably, the coins bear distinctive marks hammered into the metal, including those of a 1707 assayer from the Spanish mint in Lima, which is now Peru’s capital. Comparing these observations to historical colonial records cemented the link to the San José.

Daniela Vargas Ariza, the study’s lead author and a Maritime Archaeologist, explained that these Spanish colonial coins were frequently enough cut from gold or silver ingots.These hand-struck, irregularly shaped coins, known as cobs (English) or macuquinas (Spanish), acted as primary currency in the Americas for over two centuries.

Legal Disputes and the Fate of the Treasure

The San José wreck represents one of the most valuable underwater discoveries. Intense legal battles persist regarding salvage rights. Colombia’s government aims to recover artifacts for a national museum, hoping potential sales can fund the extensive archaeological recovery effort. However, existing Colombian law might restrict the sale of items deemed historical artifacts.

The Spanish government asserts its claim based on international maritime law. They argue that naval vessel wrecks, regardless of age, remain the property of the original nation. Colombia, however, has not ratified the specific convention cited, and critics argue such provisions intend to protect modern warship technology rather than centuries-old shipwrecks.

During the War Of The Spanish Succession, the San José led an 18-ship treasure fleet. It departed Cartagena on June 8, 1708, before British warships ambushed the ships. The San José exploded during the ensuing cannon exchange because there was an explosion in the powder room,sinking the ship and its treasure. Most of the Spanish fleet managed to reach safety in cartagena’s harbor due to this sacrifice.
