Colombian Navy divers have pulled the first physical artifacts from the San Jose galleon, a 300-year-old Spanish vessel resting off the coast of Cartagena whose cargo has been valued at $20 billion in secondary estimates. The second phase of recovery began in November 2025 and yielded a bronze cannon, three macuquinas coins, two porcelain cups, porcelain fragments, rope adhered to the cannon, and sediment samples. The haul represents the first time objects have been extracted from the protected site and brought aboard military vessels for scientific study, placing Colombia’s government in direct physical custody of cargo that remains the subject of a long-running ownership dispute.
Why the first San Jose artifacts change the ownership fight
Every object lifted from the seabed now sits under state control, and that fact carries legal weight. The Colombian government presented the recovered items in Cartagena, with President Gustavo Petro calling the recovery a historic advance in reclaiming a national cultural asset. The wreck was previously declared a national cultural-interest asset, or BIC, under Colombian law, a designation that frames any extraction as heritage preservation rather than treasure hunting.
Sea Search Armada, a U.S.-linked salvage company, has maintained a competing claim to the wreck for years. That claim has cycled through courts without final resolution. What has shifted is the physical reality: Colombia now holds artifacts aboard Navy vessels, processed through documented conservation protocols. The three macuquinas coins are especially significant because they confirm the presence of monetary cargo in the wreck zone, a point central to any valuation argument. If Colombia can demonstrate an unbroken chain of custody from seabed to laboratory, with metallurgical and provenance data generated under state supervision, the practical burden on any outside claimant to assert rights over those same objects grows substantially heavier.
The government’s approach has been deliberately framed as scientific rather than commercial. A project-level statement emphasized that the recovery serves research and heritage goals, with artifacts entering controlled-humidity and temperature environments alongside anti-corrosion precautions immediately after extraction. That framing is strategic: it positions Colombia as a custodian of shared cultural patrimony, not a commercial actor, which could influence how international tribunals weigh competing claims.
Colombian officials have repeatedly contrasted their model with traditional salvage contracts that pay private firms a percentage of recovered treasure. By channeling the work through public institutions and insisting on archaeological methods, the state is arguing that the San Jose is more akin to an underwater museum than a submerged vault. That posture could prove crucial if Sea Search Armada or any other claimant seeks compensation based on the commercial value of the cargo rather than its cultural significance.
Bronze cannon, macuquinas, and porcelain: what divers actually recovered
The November 2025 phase produced a specific and documented set of objects. According to the official project update, divers collected a bronze cannon with rope attached, three macuquinas, two porcelain cups, other ceramic fragments, and sediment. Seal analysis on the cannon has already begun, with researchers examining markings that may indicate the vessel’s origin or the cannon’s manufacturer and help correlate the piece with known Spanish armaments from the early 18th century.
The three macuquinas deserve close attention. Macuquinas were hand-struck coins produced in colonial Spanish American mints, typically in silver or gold. The official project documentation identifies them as coins but does not specify the metal composition. Secondary reporting has described them as gold, but no primary government source or assay report has confirmed this. That distinction matters: gold coins would support higher valuation estimates for the remaining cargo, while silver macuquinas, though historically significant, would tell a different story about the wreck’s commercial contents and the scale of bullion that may still lie on the seabed.
The inter-agency structure overseeing the work involves four Colombian institutions: the Culture Ministry, ICANH (the Colombian Institute of Anthropology and History), the Navy, and DIMAR (the maritime authority). This four-body framework was established before the 2024 exploration stage and was reaffirmed in a March 2024 ministerial statement that responded to public allegations about irregular interventions at the site. That statement outlined the controls, monitoring parameters, and research protocols that would govern any physical contact with the wreck, including requirements for video documentation, conservation logs, and scientific sampling plans.
The 2024 exploration stage preceded the November 2025 extraction phase, creating a two-step sequence: survey first, then selective recovery. Objects were extracted aboard Colombian Navy vessels using methods designed to preserve archaeological context, not simply pull treasure from the ocean floor. The sediment samples collected alongside the coins and porcelain suggest researchers are building environmental data about the wreck site itself, not just cataloging valuable objects. Grain size, chemical composition, and biological traces in those samples can help reconstruct how the wreck has deteriorated and how best to stabilize any future finds.
Officials have stressed that the cannon and coins were lifted from a limited area rather than from the main hull concentration, in order to test procedures and conservation workflows. That cautious approach reflects lessons from other high-profile shipwrecks where rapid, large-scale recovery led to damage and data loss. By starting small, the San Jose team can refine handling techniques, adjust storage conditions, and calibrate corrosion treatments before tackling more fragile or historically dense sections of the site.
Unanswered questions about the San Jose coins and cargo claims
Several gaps in the public record limit what anyone can conclude with confidence. The $20 billion valuation attached to the San Jose’s cargo appears in secondary reporting but has no published basis in any government assay, inventory, or appraisal document available in the official project releases. The figure has circulated for years, but its origin remains unclear, and the Colombian government has not endorsed it in formal communications. Without a transparent methodology, that number functions more as a headline-grabbing estimate than as a grounded economic assessment.
There is also uncertainty about the precise location and integrity of the main treasure hold. While Colombian authorities have released video and still images of cannons and stacked ceramics on the seafloor, they have not disclosed a detailed site map or a quantified inventory of visible cargo. That opacity is partly intentional, aimed at deterring looting and protecting a militarily guarded zone, but it complicates outside efforts to evaluate the scale of potential recovery or the strength of competing claims.
Sea Search Armada’s legal arguments rest on its assertion that it identified the wreck area decades ago and is therefore entitled to a share of whatever is brought up. Colombian officials counter that the San Jose is a sovereign cultural asset under national and international norms, and that any prior location work does not confer property rights over the ship or its contents. Court filings referenced in U.S. reporting on the dispute underscore how long-running and complex the litigation has been, with no definitive ruling that would force Colombia to treat the wreck as a commercial prize pool.
Key technical questions remain unresolved. Authorities have not yet published metal assays for the macuquinas or detailed corrosion analyses for the cannon. Those data will be crucial for dating the pieces, confirming their mint origins, and determining how representative they are of the broader cargo. Nor has the government released projected timelines for subsequent extraction phases or criteria that would trigger a shift from pilot recovery to large-scale operations.
For now, the November 2025 artifacts function as both scientific samples and legal markers. Scientifically, they inaugurate a conservation pipeline that can be expanded as more material is raised. Legally and politically, they anchor Colombia’s argument that the San Jose is being handled as an archaeological site under public stewardship. As conservation reports and peer-reviewed studies emerge, they may either reinforce the narrative of a carefully managed heritage project or expose tensions between research goals and the lure of immense, if still unproven, wealth on the Caribbean seafloor.
