The State of Shipwreck Treasure Hunting: 2016–2026

A decade of changing recovery rights, salvage operations, enforcement, technology, and the collector market for documented shipwreck material.

Finding a wreck, recovering its cargo, and legally selling an object are three different things. This report traces how government-led recovery, existing salvage rights, better survey tools, and documentation shaped the shipwreck trade between 2016 and 2026. The collector’s question is not simply ‘what was found?’ but ‘what can lawfully enter the market, with a defensible history?’

A discovery is not new market supply.

Start by separating three stages that headlines often collapse into one.

Discovery: A survey identifies a site. It does not establish ownership, permission to recover, or permission to sell.

Recovery: Objects may be raised for conservation and study under a government project or licence. They may remain public heritage.

Market entry: An object reaches collectors only when the applicable rights and disposition rules allow it. Its paperwork must follow the object.

More wreck discoveries do not automatically mean more coins for sale.

Different operators. Different destinations.

The report compares established Florida operations with state-led and museum-focused recovery. These models cannot be treated as interchangeable.

Established Florida operations: Mel Fisher’s operations on Atocha and Santa Margarita, and the 1715 Fleet operations, work within established rights and oversight arrangements. Documentation and the specific recovery agreement matter.

The Bahamas: The report describes Allen Exploration’s Maravillas project as government-licensed, with recovered material destined for conservation and museum display rather than routine collector sales.

Colombia: The San José project is presented as state-led archaeological recovery. A discovery announcement is not an offer of coins to the trade.

Ask where recovered material is going: a museum, a conservation laboratory, or a lawful sales channel.

Permission and provenance do different jobs.

Legal permission concerns the right to recover and transfer an object. Provenance concerns the documented history of that particular object. A convincing story is not a substitute for either.

Heritage protection: The UNESCO 2001 Convention provides a protection framework for underwater cultural heritage. Its application depends on participating states and relevant domestic law; it is not a universal rule that makes every recovery illegal.

State and vessel claims: Sovereign immunity — the legal protection that may apply to a state’s vessels and property — and competing ownership claims can affect historic wrecks. The report uses San José and the Mercedes litigation to illustrate why ‘finders keepers’ is an unreliable assumption.

The Schmitt case: The report recounts allegations involving undisclosed 1715 Fleet gold coins and the use of photographs and digital evidence to reconstruct their history. Its lesson is traceability, not guilt by association for every coin from that fleet.

A recovery certificate, an ownership history, and an authenticity opinion answer different questions. Check what each document actually establishes.

Better tools do not grant better title.

The decade’s survey advances explain why discoveries and commercial availability can move in opposite directions.

AUVs survey: Autonomous underwater vehicles (AUVs) run survey patterns and collect data. They can extend the reach of a search without deciding who owns what they locate.

ROVs work at depth: Remotely operated vehicles (ROVs) let teams inspect and work on deep sites. Technical access still depends on permissions, conservation plans, and project funding.

Sonar analysis and 3D recording: Machine-assisted sonar review helps identify candidates; photogrammetry records sites as three-dimensional models. These are evidence-gathering tools, not proof of commercial recoverability.

The practical bottleneck can be rights and stewardship, even when the technology exists.

Separate market evidence from the investment thesis.

The report connects constrained new supply with established collector demand. That is an argument to examine, not a promised return.

Auction turnover: The PDF cites Sedwick auction totals of approximately $4.07 million in May 2021 and $5 million in November 2025. Sale totals measure activity across a sale; they do not measure the appreciation of a single coin or a constant basket.

Bullion and collectible value: Gold and silver prices can influence an object’s melt value — an estimate of its recoverable precious metal. A collectible premium also depends on attribution, condition, demand, and documentation. Neither component guarantees the price at which an owner can sell.

Documentation: Grading, wreck attribution, recovery records, and ownership history can help buyers evaluate an object. A slab or certificate should be matched to the exact piece and read for its actual scope.

Limited supply alone does not guarantee rising prices. Evaluate the piece, the evidence, the costs, and the likely exit separately.

Treat the next five years as scenarios.

The PDF’s outlook is forward-looking interpretation. Keep it separate from the events and results on which it is based.

Recovery policy: Watch whether governments expand archaeological recovery, change licensing terms, or alter what may enter private ownership.

Collector demand: Public attention may bring new readers and collectors, but publicity does not establish durable demand for every type of material.

The risks: The report highlights regulatory changes, fraud or counterfeit scandals, and a precious-metal correction. These could weaken the thesis even if new supply remains limited.

Follow actual policy decisions and comparable sales, not just spectacular discoveries or headline valuations.
