The 8-Point Find Identification Checklist

Use this eight-point checklist before cleaning, researching or posting an unknown metal detecting find.

1. Protect the find immediately

Handle fragile objects by the edges, keep loose pieces together and avoid bending, scraping or polishing. If the object is wet, do not force rapid drying. Photograph its original condition and note whether it came from salt water, wet soil or dry ground.

2. Record the discovery context

Write down the date, general region, soil type, approximate depth and detector response. Never publish exact coordinates for a protected or archaeologically sensitive site. Context can be as important as the object itself when identifying age and use.

3. Photograph every useful angle

• Front and back photographed straight-on
• Both edges to show thickness and construction
• Close-ups of letters, seams, fasteners and decoration
• One photograph beside a metric scale

4. Measure accurately

Record length, width, diameter and thickness in millimetres. Weigh the object in grams when possible. Measurements separate similar-looking coins, buttons, buckles and fittings.

5. Describe the material carefully

Note colour, density, magnetic response and visible corrosion without guessing too confidently. Green patina can suggest a copper alloy; orange scaling often suggests iron, but surface appearance alone is not proof. Do not use acid, bleach or abrasive tests.

6. Transcribe every mark

Copy visible letters, numbers and symbols exactly as seen. Record uncertain characters with a question mark. Rotate the photograph because worn lettering may become clearer under light from another direction.

7. Compare multiple features

A single similar image is not enough. Compare dimensions, metal, attachment method, edge, lettering and construction. Prefer museum catalogues, official heritage databases and specialist references over unsourced marketplace listings.

8. Ask for a reviewed identification

Post the photographs, measurements and general region together. Clearly separate what you observed from what you suspect. Treat community answers as leads until several features and a reliable reference agree.

Frequently asked questions

Is detector Target ID enough to identify a find?

No. Target ID changes with depth, orientation, soil and nearby metal. Use it only as supporting context.

Should I clean a coin before photographing it?

No. Photograph it first and identify the likely material before choosing any conservation step.
