Detector finds on eBay: what can legally be sold, and where

A guide by Rob · Law last checked 24 September 2026

Type “Roman coin” or “Viking bracelet” into eBay and you will get pages of results. Most are listed perfectly legally. Some are not — and the difference is rarely in the object. It is in one line of the listing: where it was found.

England and Wales: mostly yes, with one big exception

In England and Wales most detector finds can be sold. A lone Roman grot, a medieval buckle, a Georgian button — none of them is Treasure, and once the finder and the landowner have agreed who owns what, they can be kept, given away or sold. That agreement is the reason the detecting code of conduct asks you to get permission in writing before you ever switch on.

The exception is Treasure, and it is wider than most people think. It covers (National Museums NI, no date a):

If you find something you believe is Treasure, you must tell the coroner within fourteen days. Not doing so is a criminal offence, with up to three months in prison, a fine, or both (Treasure Act 1996, s. 8). Treasure is offered to museums first, and it can be sold only once it has been through that process and been disclaimed.

What eBay itself requires: for potential Treasure, sellers must be able to show the Crown Disclaimer or the find’s Treasure number, and include it in the listing (eBay, no date).

Scotland: everything is reportable

Scotland does not use the Treasure Act. Under its own system every find must be reported, not only gold and silver (Treasure Trove Scotland, no date). eBay’s rule follows that: a Scottish find should carry a disclaimer certificate in the listing, showing it was reported and that the seller has the legal right to sell it. An unreported Scottish find is not the seller’s to sell.

Northern Ireland: the find itself is the problem

Northern Ireland is the one most people get wrong. The Treasure Act applies there, but that is not the main point. Searching that involves digging — metal detecting expressly included — needs a licence, and licences are only granted for archaeological projects. (National Museums NI, no date b)

So for most of us, detecting as a hobby there is not an option. A listing that says an object was “found in Northern Ireland”, with nothing about when, how or under what licence, should make any buyer stop and ask. There may be an innocent answer — a find from before the licensing rules, or something turned up by a plough rather than a detector — but it is the seller’s job to give that answer, not yours to assume it.

The Republic of Ireland: the State owns it

In the Republic, searching for archaeological objects without the Minister’s written consent is a criminal offence, carrying fines or prison (National Museum of Ireland, no date). “Archaeological object” is defined widely enough to cover coins, buttons and buckles of almost any age, and any found since 1994 with no known owner belongs to the State (National Monuments (Amendment) Act 1994, s. 2). eBay asks sellers of Irish finds to show they were reported under the National Monuments Acts and a waiver of ownership from the Minister (eBay, no date). In practice, very little found in the Republic can legitimately be on eBay at all.

Selling abroad means exporting

Every eBay listing that ships worldwide is a potential export, and exports have their own rules. Archaeological objects found in UK soil and over 50 years old need an export licence to leave the country, whatever they are worth — the value threshold for them is zero. The licence comes from Arts Council England. It is free, and the straightforward ones are usually turned round in about a week (Arts Council England, 2026; Department for Culture, Media and Sport, 2024). A seller posting a Roman coin to a buyer in the United States without one is breaking the rules, however small the coin.

It is not only the seller who can be in trouble

Buying is not risk-free either. Under the Dealing in Cultural Objects (Offences) Act 2003 it is an offence to dishonestly deal in a cultural object you know or believe to be tainted — illegally excavated or removed, in the UK or abroad — and the Act defines dealing as including buying. The maximum sentence is seven years (Dealing in Cultural Objects (Offences) Act 2003, ss. 1 and 3). The Act is aimed at people who know what they are doing, not honest buyers who were misled. But “I didn’t ask” is a weaker position than “I asked and was shown the paperwork”.

What a proper listing tells you

eBay’s own policy is plain: sellers have to include the provenance or ownership history of the object in their listing (eBay, no date). So before you buy, look for:

  1. Where it was found — the county at least, and the country without fail.
  2. When and how — on a detecting permission, a field walk, an old collection?
  3. A record — a Portable Antiquities Scheme reference for England and Wales; a Treasure number or Crown Disclaimer where it could be Treasure; a Scottish disclaimer certificate.
  4. An export licence, if it is leaving the UK.

A listing whose whole description is one line about how rare and stunning the object is doesn’t meet eBay’s own rules, whatever the object is.

Why it matters

An object’s price and its value to history are not the same thing. What makes a find matter to history is its findspot: where it came out of the ground, what it lay next to, what it tells us about who dropped it. A Viking bracelet with a recorded findspot adds a dot to the map of Viking settlement. The same bracelet with only “rare, stunning” is a nice piece of bronze, and whatever it could have told us is gone.

That is not an argument against selling finds. It is an argument for selling them properly, with the record attached, so that when an object changes hands its story goes with it.

Every legal point above was checked against these on 24 September 2026. The law changes — the definition of Treasure did in 2023 — so if something here looks out of date, tell me.

This is a plain-English guide, not legal advice. If a lot of money or a doubtful find is involved, ask a Finds Liaison Officer or a solicitor before you buy or sell.

Before you dig

Finding things is the easy part. These are the people who make a find count for something.

Scotland, Ireland and Northern Ireland

Those four are for England and Wales, where the Portable Antiquities Scheme records finds and the Treasure Act decides what must be reported.

The Republic of Ireland is different again, and severely so.

Northern Ireland is stricter still. The Treasure Act applies and finds go to National Museums NI within fourteen days, but any searching that involves digging — metal detecting expressly included — needs a licence, and licences are only granted for archaeological projects. National Museums NI ›
