European detecting atlas

Metal detecting in Europe: check the country rule first.

Europe is not one detecting rulebook. Start with the country, confirm the exact land and protected status, then record an old find before you remove its clues.

First two country guides

Same hobby. Different legal route.

These guides use official national sources, show the review date, and still send you back to the exact land manager.

ENGPermission + protected-site check

England

Public access is not detecting permission.

Get owner and occupier permission. Avoid scheduled monuments without Section 42 consent. Report suspected Treasure within 14 days.

NLD30 cm limit + local APV

The Netherlands

Permission is only the first checkpoint.

Stay on land and within the top 30 cm. Protected monuments, active excavations, underwater sites, and local bans sit outside that route.

The safe map layer

A map should name the authority—not reveal a site.

For historic ground, a useful map explains the legal route. It should never expose a burial site or exact findspot.

Historic find routes

Preserve the clues before naming the coin.

Metal, diameter, weight, portrait, letters, reverse design, and find context work together. One clue alone is not an identification.

Roman

Portrait, legend, reverse, mint.

Follow a visual decision tree, move through the imperial timeline, and compare possible matches in OCRE or PAS.

Open Roman Coin Identification

Medieval / hammered

Cross, bust, pellets, mint name.

Use the surviving design—even on a clipped or cut fragment—to build a careful shortlist.
