Object identifier appraisal record basics
Object identifier appraisal records help connect a physical item to photos, measurements, marks, condition notes, provenance documents, and market evidence. A code, label, barcode, inventory number, or old file name is useful only when it is tied to verifiable records.
Appraisers see identifiers in auction exports, dealer databases, museum labels, conservation invoices, estate spreadsheets, photo file names, and handwritten receipts. The identifier is not proof of authenticity by itself. It is a key that helps you find and organize evidence.
This guide uses the Object ID approach: document what the object is, how it looks, where identifying marks appear, and which records support the item history. The goal is a clean crosswalk from number to object to evidence.

Check whether the identifier supports the appraisal file
Upload the object, labels, inscriptions, back or underside, old receipts, appraisals, auction records, and condition photos. The free screener can flag whether the number is useful evidence or just an internal code.
Start with a free screener. Use a signed report only if you need insurance, estate, donation, or sale documentation.

What to record for each object identifier
A useful appraisal record captures both the code and the evidence around it. Record the identifier exactly as it appears, including capitalization, spaces, dashes, slashes, and handwritten ambiguity. Then document where the identifier appears and which source supplied it.
- Photographs: full object, front/back or top/underside, close-ups of labels, inscriptions, stamps, tags, and condition issues.
- Object description: type, title, maker or attribution, materials, dimensions, date or period, subject, edition, and distinguishing features.
- Identifier location: frame back, stretcher, underside, base, tag, box, receipt, conservation label, auction lot page, or file name.
- Source document: invoice, appraisal, consignment agreement, catalogue, conservation report, insurance schedule, or estate inventory.
- Confidence note: direct match, likely match, related record, or unresolved conflict.
Build a crosswalk, not a single-number story
One object can carry many numbers: a collector inventory number, an auction lot number, a dealer stock code, a conservation job number, a shipping label, and your own file ID. A crosswalk ties those numbers to the same physical object without pretending they all mean the same thing.
The crosswalk should explain which number came from which source, when it was used, and what it proves. A conservation job number may prove treatment history. An auction lot number may prove sale history. A museum accession number may prove collection history. None of them automatically proves authorship or age.
Identifier evidence table for appraisal files
This table is not a price-comps table. It is the evidence structure to keep beside comparable sales so reviewers can trace how each record connects to the physical object.
| Photo | Record type | Date | Identifier | Value role | Notes | Source |
|---|---|---|---|---|---|---|
| Photo | Object label or inscription | Current | Exact code as found | Links physical item to file | Photograph with scale and location context; do not transcribe from memory. | Owner photos / inspection |
| Scan | Dealer or gallery invoice | Sale date | Stock or inventory number | Supports provenance and purchase history | Check description, dimensions, and buyer/seller names against the object. | Invoice or receipt |
| Record | Auction lot record | Sale date | Lot number or archive ID | Supports market evidence | Confirm image, title, medium, size, and condition before using it as a comparable. | Auction archive |
| Report | Conservation report | Treatment date | Job number | Explains condition and restoration | Link treatment notes to current condition photos and disclose major interventions. | Conservator file |
| Inventory | Estate or insurance schedule | Schedule date | Internal file ID | Supports ownership and retention history | Use as provenance context, not as proof of authenticity or current value. | Estate / insurance record |
Takeaway: the identifier becomes useful when every number is tied to a photo, document, date, source, and confidence note.
Have labels or old numbers?
Organize the evidence before relying on the code.
Upload the object, labels, receipts, old appraisals, condition photos, and any auction or gallery records. The free screener can flag what belongs in the appraisal file.
Use the free screenerHow to interpret identifier patterns safely
Some identifiers contain dates, department prefixes, sequence numbers, or checksum-like endings. Pattern analysis can tell you where to search next, but it should not become the conclusion. Treat every decode as a lead until a source document confirms it.
- Date-like segments: ask for intake logs, consignment records, or file folders from that period.
- Department prefixes: ask the source whether the prefix maps to art, jewelry, furniture, silver, books, or another department.
- Image file names: keep original filenames because they may connect to an export, lot folder, or CMS record.
- Conflicting numbers: pause and investigate; mismatched dimensions, titles, or materials may mean a swapped frame, copied label, or unrelated file.
How to cite identifiers in an appraisal report
Put identifiers in the object description and repeat them in an appendix. Distinguish source IDs from your internal file number. A clean format might read: "Dealer inventory number: GNY-17-134; conservation job number: CL-2022-015; Appraisily file ID: AP-2026-0412."
In the valuation section, use identifiers to show that each comparable sale, prior receipt, or conservation note is tied to the same object or to a comparable object of the same maker, period, material, and condition tier.
