Are Ancient Roman Coins Legal to Own? A Country-by-Country Guide

Last updated: 12 May 2026 · Author: Aurora Antiqua Editorial · Reading time: 8 min

Quick answer: Yes, in most Western countries, including the EU member states, United Kingdom, United States, Canada, Switzerland, and Australia, owning and trading ancient Roman coins from documented private collections is fully legal. Restrictions apply to coins exported from source countries (notably Italy, Greece, Turkey, Egypt, Bulgaria, and Cyprus) after their respective cultural-property laws came into force. Provenance matters: a coin from an old European or American collection is unproblematic; a coin without provenance from a source country may be restricted.

The two legal questions

Whether you can legally own a Roman coin depends on two separate questions:

1. Was it legally exported from its country of origin? Most source countries restrict export of antiquities found on their soil. Coins exported before these laws took effect, or sourced from old collections established before them, are unrestricted.
2. Is it legal to own in your country? Almost always yes in Western jurisdictions, as long as the coin was legally imported.

Provenance (the documented history of a coin's ownership) links these two questions. A coin in a 1970s auction catalogue is exempt from most cultural-property laws because it predates them.

What "provenance" means in practice

Provenance is the documented chain of ownership of a coin. In ascending order of strength:

1. Old collection ticket, a handwritten or printed ticket from a previous owner, attached to the coin or stored with it. Common, low-evidentiary, but a useful signal.
2. Dealer invoice, a written invoice from a recognised dealer, especially one with a long-established business.
3. Published auction catalogue entry, the coin appears in a printed catalogue with photograph and lot number. Strong evidence.
4. Museum or institutional deaccession, extremely rare for ancient coins, but unimpeachable when present.
5. Pre-1970 documentation, anything proving the coin was outside its source country before the 1970 UNESCO Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property. This date is widely treated as the benchmark.

The 1970 UNESCO Convention is the key reference date. Coins documented as in a private collection before 1970 are generally accepted across all Western jurisdictions without further evidence.

How Aurora Antiqua handles provenance

Every coin we list includes the provenance information available to us. We source from:

• Old European private collections (mostly British, German, Belgian, French) with collection history pre-dating the modern cultural-property regime
• Established auction houses (CNG, Roma Numismatics, Naville Numismatics, Heritage, Künker) where lots are vetted before sale
• Documented dealer estates with paper trails

We do not purchase coins:

• Offered without any provenance from sellers in or near source countries
• Lacking adequate documentation where the metal value alone would otherwise tempt purchase
• With provenance that mentions undocumented "metal detector finds" in countries where this is restricted

When provenance is limited to "old European collection" we say so. We do not invent provenance.

Import to your country: practical guidance

Importing to the United States

The U.S. Customs and Border Protection enforces CBP regulations and CCPIA agreements. For a coin shipped from Belgium to the US:

• Coins valued under approximately $2,500 typically clear with the commercial invoice alone
• Coins of specific types restricted by a CCPIA bilateral agreement (notably Italian provincial coinage and some Greek issues) require evidence of pre-restriction provenance
• Aurora Antiqua provides a description, declared value, and provenance note with every shipment

Importing to the UK

Post-Brexit, the UK requires:

• Standard customs declaration
• VAT (currently 20%) on the import value for most coins, though some categories qualify for the 5% reduced rate for collectors' items
• Cultural-property declaration only for shipments from outside the EU when the coin's value exceeds £39,000

Importing within the EU

Single-market trade, minimal documentation, no import duty between member states. VAT is applied at point of sale per the seller's country (Belgium for Aurora).

Importing to other countries

The general rule: any coin with documented pre-1970 ownership history clears without issue almost anywhere. Coins from source countries without documentation may be detained pending evidence.

What about metal-detector finds in your own country?

This is a separate question from the trade question.

A coin you find with a metal detector in a country where this is legal can be kept (subject to reporting rules). A coin imported from somewhere it was illegally extracted cannot.

Frequently asked questions

Can I sell an ancient coin I inherited from a grandparent? Almost always yes. Family inheritance is itself provenance, and a coin in a family collection for 50+ years almost certainly predates current cultural-property frameworks. A photograph of the coin in a grandparent's collection ticket or letter is helpful but not required.

Do I need an export licence to buy a coin from Aurora and ship it home? For shipments within the EU, no. For shipments to the US, UK, Canada, Australia, Japan, etc., Aurora provides the standard customs documentation; no special licence is needed for coins not subject to a CCPIA bilateral agreement.

What if I want to sell a coin I bought from Aurora later? You receive the same provenance information we held. You can re-sell to any dealer or auction house. The provenance "Acquired Aurora Antiqua, [date]" is itself an addition to the coin's documented history.

Are gold Roman coins (aurei, solidi) treated differently? In some jurisdictions yes, gold may attract additional import duties or VAT. Cultural-property restrictions are the same as for bronze and silver: provenance, not metal, is the trigger.

Why don't Aurora's listings always show a 1970-pre provenance? Most ancient coins surfaced from old collections without dated documentation. We say what we know: where we acquired the coin, the prior dealer if applicable, and any collection history disclosed at acquisition. Honesty about gaps is more useful than invented certainty.
