Key points

Identify what the mixed collection can already support

Transcribe packaging, documents, old labels and provenance only when their wording is clear. Do not complete a missing statement from another object in the group.

Evidence available in the first pass

Keep face and edge orientation fixed while marking an uncertain name, period or material under the object's number. Preserve the first image and reading.

Questions that remain open

When material, count or current name is obscured, state why. Check whether an overall photograph has cropped an edge before requesting another view.

A case name or transaction context is not proof of origin. Only the material evidence belonging to the collectibles is carried into the description.

A batch image should establish quantity only

Separate a mixed holding into metal, paper, stamps, porcelain and other materials. Preserve each original unit and avoid placing unlike objects under the same assessment heading.

After the group photograph, give every object a complete view, tentative name, dimensions or weight, current packaging and locatable damage.

Keep provenance apart from visible facts

Preserve boxes, sleeves, certificates, receipts and labels as found, matching each one to an identifier rather than assuming the whole batch shares them.

A family account can be retained as context, while the object's features, open questions and document wording remain separate.

Different materials require different descriptions

Use a new identifier for each object and keep its complete outline, faces, edge, underside and measurement images together where appropriate.

Support the material group safely: no cleaning of metal, no pressing of paper, no forced removal of stamps and no lifting porcelain from a vulnerable rim.

Do not guess an uncertain name

Images can reveal inscriptions, designs and obvious damage; material, concealed cracks, paper structure and fine repairs may still need direct examination.

Mark an uncertain name or date explicitly. Completing a table is not a reason to turn resemblance into evidence.

A practical mixed-collection handover

Begin with the package, documents, labels and provenance, then connect them to separately supported and photographed objects. Note every visibility restriction.

Add the material, item count and working name only as far as direct evidence allows. A new identification should retain the earlier wording and date.

Keep the original files unfiltered and add improved views separately. This preserves colour, orientation and the first condition reference.

Check identifiers on objects, images, measurements and attachments before movement. An unmatched label remains outside the object description.

For appraisal, maintain the existing surface and enclosure while clearly naming the material or condition question that requires specialist access.

文章 FAQ

What is the first useful division for mixed collectibles?

Separate metal, paper, stamps, porcelain and other materials, then assign one identifier to each object. Give every item its own complete photographs, original measurements, packaging and open questions.

How should packaging and provenance be described?

Transcribe boxes, sleeves, certificates, receipts, labels and family accounts as supporting context under the matching identifier. Keep visible object condition and unconfirmed statements separate, especially when they disagree.

Which details should remain open for direct examination?

Leave material, hidden cracks, paper structure, fine repairs, obscured markings and unsafe-to-open areas unresolved when photographs cannot establish them. Do not clean, press, detach or dismantle the object to fill a blank.
