COLUMBIA – The historic discovery of the San José galleon has officially set a new record for the largest treasure ever found, valued at an astonishing $17.4 billion.

Located off the coast of Cartagena, Colombia, this Spanish warship sank in 1708 while carrying approximately 180 tons of gold, silver, and precious stones from Peru. The confirmation comes after years of speculation, with recent archaeological findings providing conclusive evidence of the ship’s identity.

However, this monumental discovery has ignited an intense diplomatic battle between Spain and Colombia over rightful ownership.

The sunken Spanish galleon and its unprecedented treasure

On June 8, 1708, the San José galleon met its fate during a naval battle with British warships. As the flagship of the Flota de Tierra Firme, this vessel held a monopoly on transferring precious metals from the Americas to Spain. The ship wasn’t merely a cargo vessel but a critical component of Spain’s transatlantic trade network.

While the Colombian government announced locating the wreckage in 2015, formal identification remained pending. It wasn’t until specialized underwater expeditions in 2021 and 2022 that researchers recovered the first gold pieces from the site, located 600 meters below sea level. These artifacts have now undergone rigorous analysis, confirming the ship’s identity beyond doubt.

The treasure’s estimated value of 16 billion euros surpasses the previous record holder – the Sree Padmanabhaswamy temple treasure in India, valued at approximately 15 billion euros. This makes the San José galleon’s cargo officially the most valuable historical treasure ever discovered in human history.

The archaeological significance extends beyond monetary value. The ship represents a perfectly preserved snapshot of colonial Spanish commerce, with each artifact telling a story about global economic systems based on resource extraction from the Americas.

Scientific confirmation through advanced archaeological methods

Colombian researchers employed sophisticated techniques to verify the wreckage’s identity. Through photogrammetry, they created high-resolution 3D models of recovered coins, revealing crucial details about their origin and authenticity. The analysis confirmed these coins were:

  • Minted in Lima, Peru in 1707
  • Hand-struck with irregular shapes (known as “macuquinas”)
  • Bearing the distinctive coat of arms from the Crowns of Castile and Leon
  • Made of raw gold extracted from colonial mines

These characteristics align perfectly with historical records of the San José’s cargo manifest. The coins’ irregular form was typical of colonial Spanish currency – less refined than European counterparts but remarkably effective for the economic systems of the time. Their distinct features provided researchers with indisputable evidence of the wreck’s identity.

The scientific paper published in Antiquity journal (Vargas Ariza et al., 2025) details the comprehensive analysis that led to this confirmation. High-resolution photographs taken at the wreck site show coins scattered across the port side of the stern, preserved remarkably well despite three centuries underwater.
