Give every coin a stable identifier
Create a unique inventory number and photograph both sides with a scale. Record diameter, weight as measured, visible inscriptions, condition and existing labels. Avoid aggressive cleaning to “read” a legend; surfaces may carry evidence and conservation value.
Separate numismatic description from ownership
A catalog attribution may identify a ruler, mint or period, but that does not establish when or how the coin entered a modern collection. Record acquisition date, seller, invoice number, shipping records and any earlier collection references in distinct fields.
Treat old envelopes as research leads
A handwritten coin envelope might contain a collector name or auction number. Photograph and preserve it even if the attribution turns out to be outdated. Match auction plate images carefully; small differences can identify a different specimen.
Check applicable restrictions
Export and import requirements for archaeological or numismatic objects vary by country and category. Ask for documentation relevant to origin and current jurisdiction; a dealer’s guarantee cannot override law. If the chain is weak, seek specialized legal or numismatic advice before purchase or transfer.
What to do next
- Assign each coin a unique inventory ID
- Photograph both faces and preserve old envelopes
- Record attribution separately from ownership
- Link invoices and prior catalog appearances
- Review jurisdiction-specific transfer restrictions
Common questions
Does a coin identification establish legal title?
No. Identification and ownership are separate questions.
Should I clean coins before photographing them?
Avoid unapproved cleaning; consult a specialist about preservation.
Cultural-property compliance varies by jurisdiction. Style and seller documents do not establish lawful title. Obtain independent professional advice and avoid inadequately documented material.
