Your first few outings will produce a pouch full of odd bits of metal, and most of it will be rubbish. But mixed in with the ring-pulls are things that are hundreds or even thousands of years old, and learning to recognise them is half the fun of the hobby. Here are the finds UK detectorists turn up most often, roughly from most common to least.

Modern rubbish (you’ll find lots of this)

Everyday historic finds

FindRoughly how oldHow to recognise it
ButtonsMostly 17th–19th centuryFlat copper-alloy discs with a loop (shank) on the back. Some have makers' marks or livery designs
Musket balls and lead shotMostly 16th–19th centuryRound lead balls, often with a seam or a flat spot where they hit something
Lead weights and fishing weightsMedieval to modernLead lumps, discs or cones, sometimes with a hole
Victorian and Georgian coppers18th–19th centuryLarge copper pennies and halfpennies, often very worn
BucklesMedieval to 19th centuryCopper-alloy frames, often broken. Shapes change a lot over time, which helps with dating
ThimblesMedieval to modernSmall copper-alloy thimbles with dimpled surfaces, often squashed
Crotal bellsMostly post-medievalSmall round bells with a slot, once used on horse harness and livestock
TokensEspecially 17th centurySmall coin-like pieces issued by traders, often with a name and town

The finds everyone hopes for

Hammered coins. Before milled coinage took over in the 17th century, English coins were struck by hand with hammer and dies. Hammered silver pennies, groats and their cut halves and quarters are the finds many UK detectorists prize most. They’re usually thin, irregular in shape, and often show a cross on the back.

Roman coins. Small bronze Roman coins, many from the 3rd and 4th centuries AD, are among the most common ancient finds in England. They’re often dark and worn, and detectorists nickname them “grots”. Silver denarii and siliquae turn up less often.

Brooches. Roman bow brooches, Anglo-Saxon brooches and medieval brooches are all found by detectorists and are very collectable.

Medieval and later jewellery. Rings, pendants and dress fittings, occasionally in gold or silver.

Could it be treasure? Gold and silver objects over 300 years old, and some other finds, may legally count as treasure and must be reported within 14 days. See our treasure guide. And don't clean old finds. It can destroy detail and value. Our cleaning guide explains why.

How to identify what you’ve found

  1. Search the Portable Antiquities Scheme database. The PAS database at finds.org.uk contains well over a million recorded finds, with photos and descriptions. Search for the type of object and browse similar examples.
  2. Show it to your Finds Liaison Officer. FLOs identify and record finds for free, and you get your find back. It’s the best way to put a date on an object and add it to the historical record.
  3. Ask at your club. Experienced members have usually seen it before. See our guide to clubs.
  4. Use a good reference book. Two standard references for UK detectorists are below.
