treasure
Enable an AI agent to recognise a physical object or assemblage treated as treasure, assess the evidence for its significance and condition, and determine appropriate handling, investigation and disposition.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a physical object or assemblage treated as treasure, assess the evidence for its significance and condition, and determine appropriate handling, investigation and disposition.
Treasure is a legal and archaeological class of portable valuables - chiefly precious-metal objects, coins, jewellery, and associated artefacts - recovered after concealment, loss, wreck, or deliberate deposition, and treated as a distinct find-category rather than ordinary lost property or commercial cargo.
It can be Evaluate a treasure designation against documented evidence and competing interpretations.; Reconcile constituent inventories while preserving uncertain membership and missing portions.; Record deposit context and discovery evidence before disturbance or separation.; Compare material, cultural and historical significance without collapsing them into one price.; Determine whether proposed examination, recovery, disclosure or transfer has adequate evidence and permission.; Prepare preservation and custody handoffs that retain object associations and contextual records..
Distinguishing features
A physical object or assemblage is identified or hypothesised, rather than treasure being only a metaphor for something cherished.
A person, community or institution attributes exceptional worth or significance to it; record who makes that designation and why instead of treating material price as sufficient.
Where several objects are called one treasure, evidence supports their grouping, such as shared deposition, documented historical association or an explicit collecting context.
Concealment or loss alone does not establish treasure status: distinguish an ordinary cache or lost object from an assemblage whose treasure designation has an evidenced basis.
Everyday treasure designation is distinguished from any formal legal classification; neither classification is inferred solely from age, gold content or discovery underground.
Scope
+ Evidence supporting or contesting the designation of an object or assemblage as treasure
+ Membership, arrangement and completeness of a treasure assemblage
+ Deposition, concealment, discovery and recovery context
+ Material, historical, cultural and attributed significance
+ Custody, competing claims and permissions affecting treasure-specific actions
+ Condition, contextual integrity and readiness for examination or recovery
- Complete typologies and manufacture histories of individual coins, jewels, artworks or other constituent objects
- The full archaeological site, landscape or building containing the treasure
- General legal systems, court proceedings and jurisdiction-wide treasure law
- Treasure-hunting expeditions, excavation projects and their operational plans
- Sales, insurance contracts and financial portfolios involving the treasure
- Metaphorical treasures, fictional loot and digital game assets
Characteristics
- Treasure designation basis
- Material worth, historical significance, cultural significance, personal significance, formal classification, other stated basis; multiple values allowed Makes explicit why this object or assemblage is being treated as treasure and whose criteria apply.
- Physical existence evidence
- Directly observed, documented but not inspected, reported, hypothesised, disputed Separates an accessible treasure from an unverified account or suspected deposit.
- Assemblage membership
- Links to constituent objects or groups, with inclusion evidence and uncertainty Prevents nearby finds or later additions from silently becoming part of the treasure.
- Constituent count
- Number of objects, fragments or lots, with counting basis and uncertainty Supports reconciliation of recovered, missing and transferred portions.
- Deposit interpretation
- Deliberate concealment, stored wealth, offering, accidental loss, transport loss, later collection, other, unresolved Distinguishes observed arrangement from hypotheses about how the treasure came together.
- Recovery state
- Location unknown, located and undisturbed, exposed, partly recovered, fully recovered within a stated boundary, dispersed Determines which interventions remain possible and what contextual evidence is at risk.
- Contextual integrity
- Apparently undisturbed, disturbed but documented, mixed, substantially undocumented, unknown Indicates how reliably arrangement and associations can support interpretation.
- Assessed value
- Currency amount or range, with date, valuation basis, assessor and included constituents Keeps financial estimates comparable without substituting price for other forms of significance.
- Claim and custody relationships
- Links to finders, custodians, asserted owners, source communities and deciding authorities, with each role distinguished Avoids treating possession, discovery or an asserted claim as proof of ownership.
- Intervention sensitivity
- Context loss, corrosion or environmental change, fragile enclosure, mixed-material incompatibility, security exposure, other documented concern Identifies what could be damaged or irreversibly lost through exposure, separation or treatment.

Designation and significance Why this physical thing is called treasure and what would be lost if its significance were misread.
Treasure is an attributed status that requires an explicit basis beyond the presence of valuable material.
Designation evidence
The physical referent, designating parties and criteria behind the treasure label.
Basis for treasure status
Record who calls the thing treasure, their reasons and the evidence that the physical referent exists.
- What object or assemblage is being called treasure, by whom and on what stated basis? definition
- Which observations or records support its existence and designation, and which parts remain reported or disputed? provenance
Forms of significance
The distinct sources of worth attributed to the treasure.
Value beyond material content
Keep material value, assemblage significance and community meanings distinguishable, including disagreements.
- What significance depends on the treasure remaining associated rather than being valued as separate objects or raw material? boundary
- If a financial estimate is used, what date, currency, constituents and valuation basis does it cover? measurement
Assemblage and completeness What belongs to this treasure and how its surviving portions relate.
A treasure may be distributed across fragments, recoveries and collections, making its boundary consequential.
Membership boundary
Evidence for including objects, containers and associated materials.
Supported constituent associations
Record confirmed and proposed members without equating proximity with common origin.
- Which objects, containers or residues belong to the treasure, and what supports each inclusion? boundary
- Which nearby finds or later additions are excluded or uncertain, and why? boundary
Survival and dispersal
Known quantities, missing portions and separation across holdings.
Reconciled treasure extent
Distinguish present holdings from the estimated original deposit and the extent actually investigated.
- How many objects, fragments or lots are documented, and how are duplicate records and joined fragments reconciled? measurement
- What evidence identifies missing, unrecovered or dispersed portions, and how uncertain is the original total? provenance
Deposit and discovery How the treasure came to its recorded setting and how that setting was encountered.
Deposit and discovery evidence can explain the assemblage while being destroyed by its recovery.
Deposition context
Observed arrangement and interpretations of concealment, storage, offering or loss.
Deposit observations and interpretations
Separate physical observations from proposed depositional events and motives.
- What arrangement, enclosure, stratigraphic relationship or environmental setting was observed before disturbance? provenance
- What evidence supports concealment, storage, offering or loss, and which alternatives remain plausible? provenance
Discovery and recovery sequence
The sequence through which the treasure became known, exposed and removed.
Traceable recovery context
Record discovery accounts, recovery episodes and their effects on surviving evidence.
- Who encountered or recovered each portion, when, and which contemporaneous records support the account? provenance
- What context was disturbed or lost during each episode, and what remains available for examination? boundary
Claims and authorised disposition The relationships and decisions that govern access, recovery and the treasure's destination.
Discovery, custody, ownership and cultural affiliation can point to different parties and permit different actions.
Claims and classification
Asserted interests and any documented formal treasure classification.
Separated rights and roles
Record the basis and status of claims without converting an assertion or custody relationship into a settled right.
- Who holds, claims or asserts a cultural relationship to the treasure, and what evidence supports each distinct role? provenance
- Has a competent authority classified this find under an applicable treasure regime, and what decision and jurisdiction establish that status? provenance
Action-specific permissions
Evidence needed to decide a particular intervention or disposition.
Permitted next action
Relate permissions, unresolved claims and disclosure controls to the action being considered.
- For the proposed recovery, sampling, separation, display or transfer, whose permission is required and what documents its scope? action
- What unresolved decision or restriction affects that action or the disclosure of the treasure's precise location? action
Preservation and evidence retention How to preserve both treasure constituents and the associations that make them informative.
Recovery and treatment can preserve valuable objects while losing enclosure, arrangement, residues or other evidence of the treasure as a whole.
Exposure and material response
Observed condition and vulnerabilities associated with exposure or changing surroundings.
Recovery-sensitive condition
Identify condition concerns for enclosed, joined or mixed-material constituents before choosing handling methods.
- Which constituents or enclosures show instability, and what observations or assessments establish their condition? measurement
- What assessment is needed before opening, lifting, drying, cleaning or separating this treasure? action
Association-preserving treatment
Documentation and treatment choices that retain assemblage-level evidence.
Retain context through intervention
Make potential evidence loss explicit when examination, conservation or transfer changes the assemblage.
- Which arrangements, residues, attachments or container relationships must be documented before the proposed intervention? action
- How will separated constituents, samples and their records remain traceable to their original positions and recovery episodes? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Real-world use
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Metal-detectorists reporting gold, silver, coin and prehistoric-metal finds to Finds Liaison Officers and coroners in England and Wales.

- Conservation damage from over-cleaning, unstable reconstruction, or poor storage.
- Which of these failure modes and hazards hold for the sense of treasure this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- England, Wales and Northern Ireland: Treasure Act 1996 uses metal, age (commonly 300 years for precious metal), and assemblage tests, including some prehistoric base-metal hoards.
- Scotland: treasure trove covers all portable antiquities of archaeological interest with no known owner, not only precious metal.
- Republic of Ireland: archaeological objects are in principle State property; detecting is tightly licensed.
- United States: no general federal treasure-trove statute; ordinary finders' law at state level, plus the Abandoned Shipwreck Act for many wrecks.
- Civil-law Europe: archaeological finds are commonly state patrimony rather than finder's treasure.
- Spain and several other coastal states treat historic wreck cargoes as national heritage, rejecting commercial 'treasure salvage' title (as in the Odyssey Marine / Black Swan litigation).
- Which of these regional variation hold for the sense of treasure this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Lost property (waif) - Lost property was not concealed with intent to recover and is handled by ordinary lost-and-found or finders' law, not treasure inquest.
- Archaeological artefact in general - An artefact is any cultural object from a deposit; it is treasure only if it also meets a precious-metal, age, assemblage, or national-patrimony test.
- Wreck (maritime) - Wreck is vessel and cargo remains under salvage or wreck law; it becomes 'treasure' only where a heritage or precious-find statute also applies.
- Bullion in commerce - Bank or refinery metal is produced or held as a commodity, not recovered as a find with unknown owner.
- Booty or prize - Property taken in armed conflict under prize or looting rules, not a deposited or lost assemblage later found.
- Archaeological hoard - A hoard is a deposited assemblage as an archaeological fact; it may fail a legal treasure test (wrong metal, too recent, or outside the statute).
- Cultural property / heritage object - UNESCO/ICOM cultural property is a broader export-and-protection class; most heritage objects are not treasure, and some treasure is not listed cultural property.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of treasure this model covers, and on what evidence? provenance

What the second pass must settle
- Does the registry intend treasure to include individually cherished physical objects and openly held collections, or primarily concentrated wealth associated with concealment, loss or discovery?
- Does an existing world model already own treasure or an equivalent concept, requiring this registry entry to link to it?
- What evidence threshold should distinguish reported or hypothesised treasure from a recognised physical instance?
- When an assemblage is dispersed, supplemented or partly reunited, what preserves its identity as the same treasure?
- Which jurisdictional classifications and community understandings must be researched for intended uses without imposing one definition of treasure universally?
