Florida Treasure Hunting Laws: Permits, Penalties, and Taxes

Florida treasure hunting laws claim state ownership of virtually every abandoned artifact, shipwreck, and piece of treasure trove sitting on state-owned land or state submerged seafloor, and excavating without a permit from the Division of Historical Resources is a third-degree felony carrying up to five years in prison. Casual metal detecting is legal in many places, but anything more than 50 years old still belongs to the state. The rules depend heavily on where you search and what you’re doing when you find something.

What the State Owns

Florida’s policy is blunt. All treasure trove, artifacts, and objects with historical or archaeological value abandoned on state-owned lands or state sovereignty submerged lands belong to the state, with title vested in the Division of Historical Resources within the Department of State.¹ The definition of a historic resource is broad: monuments, Native American sites, abandoned settlements, sunken ships, engineering works, coins, and artifacts of any kind relating to the history or culture of the state.²

Ownership is automatic. No one has to post a sign or tell you a site is protected. If it sits on state-controlled land and has historical or archaeological value, the state already owns it.

Where State Ownership Stops

Florida state waters run from shore to three nautical miles into the Atlantic and from shore to nine nautical miles into the Gulf of Mexico.³ Everything inside those lines is sovereignty submerged land, and the state’s claim over abandoned historical resources applies in full to shipwrecks, submerged prehistoric sites, and scattered cargo.

Beyond those limits, the federal Abandoned Shipwreck Act takes over. The United States asserts title to any abandoned wreck embedded in a state’s submerged lands, embedded in state-protected coralline formations, or located on state submerged lands and eligible for the National Register of Historic Places, then transfers that title to the state where the wreck sits. The traditional law of salvage and the law of finds do not apply to shipwrecks covered by the Act.⁴ Finding a wreck does not give you rights to it.

Private land is different. The state’s archaeological claim does not automatically reach onto private property, and common-law rules take the lead: the landowner controls access, and anything found generally belongs to the landowner, not the finder. Searching without express permission is trespassing. There is one important exception. The Division can designate a significant site on private property as a state archaeological landmark or part of a landmark zone, with the written consent of the property owner. Once designated, no one may conduct field investigations there without a Division permit, and the same criminal penalties apply.¹

Metal Detecting on Beaches and Public Land

Most county-managed public beaches allow metal detecting without a permit, but local governments set their own rules and some counties prohibit detecting or digging on the beach outright. Call the county or municipality that manages the beach before you go.

Florida state parks are much more restrictive. Metal detecting is prohibited on all state park lands except coastal parks, where it may be allowed within certain beach areas between the toe of the dune and the high-water line, as designated by the park manager. Detecting in submerged locations within state parks is never permitted.⁵ Call ahead to confirm which section of any given beach is open.

Even where detecting is legal, the age of the object controls what you can keep. Any item more than 50 years old is treated as an archaeological artifact, and title belongs to the Division of Historical Resources. You cannot lawfully take it home.⁵

National parks, monuments, and national seashores in Florida are off-limits entirely. Federal regulations prohibit possessing or using a metal detector, magnetometer, or any similar device within national park boundaries.

Permits for Excavation and Salvage

Any archaeological fieldwork on state-owned land, which includes state parks, preserves, forests, wildlife management areas, trails, university grounds, and all sovereign submerged lands, requires a permit from the Division of Historical Resources before you start.⁶

Research permits go to museums, universities, colleges, or other historical and scientific institutions the Division considers properly qualified to carry out systematic field research and produce a publishable report. The project archaeologist must meet the Secretary of the Interior’s Professional Standards for Archaeology, which requires a graduate degree in anthropology, archaeology, or a closely related field, at least a year of professional experience, and a demonstrated ability to carry research to completion.⁶ This is not a hobbyist permit.

The Division also has authority to issue commercial salvage permits for exploration and recovery at historic shipwreck sites on sovereignty submerged lands. Because the state owns all recovered specimens, the arrangement works as a trade: the salvor does the work, and Division rules determine what portion of the finds or their value the salvor receives as compensation for services provided to the state.¹ Everything recovered under any Division permit remains state property, with title vested in the Division.

Penalties for Digging or Trafficking Without a Permit

Florida separates non-excavation disturbance from actual excavation and punishes the latter far more heavily.

Conducting archaeological field investigations, removing, defacing, destroying, or otherwise altering any archaeological site on state land or within a designated state archaeological landmark without a permit is a first-degree misdemeanor, punishable by up to one year in jail.¹⁷
Excavating any archaeological site on state-controlled land, water authority land, or within a designated landmark without a permit is a third-degree felony, punishable by up to five years in prison and a $5,000 fine.⁸
Offering for sale, purchasing, or exchanging any object known to be illegally collected, or soliciting someone else to violate these rules, is also a third-degree felony with the same penalties.¹

The Division can also bring a separate administrative proceeding and impose fines of up to $500 per day against anyone who explores for, salvages, or excavates treasure trove, artifacts, or shipwrecks on state-controlled land without written permission. Both felony and misdemeanor convictions require forfeiture of all collected specimens, photographs, and records. For felony violations, any vehicle or equipment used in the offense can be seized, and the court may order restitution for the archaeological and commercial value of the damage plus restoration costs.¹

Reporting What You Find

Separate from the archaeological rules, Florida law imposes a general reporting duty for any found property, historical or not. If you find lost or abandoned property, you must report a description and its location to a law enforcement officer. The officer will ask whether you want to make a claim if no rightful owner comes forward. If so, you’ll need to deposit a reasonable sum with the agency to cover transportation, storage, and the cost of publishing notice.⁹

Keeping found property without reporting it is theft. Anyone who appropriates lost or abandoned property to their own use, or refuses to deliver it when required, is punished under the state’s general theft framework, with severity scaling to the value of what was taken.⁹

Federal Tax on Treasure You Legally Keep

People who lawfully recover valuable items face a federal obligation that surprises many finders. Under Treasury regulations, treasure trove is gross income in the taxable year in which you take undisputed possession of it, valued in U.S. currency at fair market value.¹⁰ The IRS does not care how you came to possess it. If it has value and you control it, it’s income.

Fair market value for artifacts and collectibles is determined by comparable sales, replacement cost, and the opinions of professional appraisers.¹¹ Florida has no state income tax, so the federal bill is the only income tax concern. If you later sell recovered items at a profit, gains on collectibles held longer than one year are taxed at a maximum federal rate of 28%, higher than the standard long-term capital gains rates that apply to stocks and most other assets.
