How records are made

Accuracy is valued above scale. A small, properly sourced catalogue is worth more than a large speculative one.

Source-first workflow

  1. 1

    Identify sources

    Locate standard catalogues, museum records, archives and specialist literature for the field before any record is written.

  2. 2

    Evaluate sources

    Rank each by authority, primary or secondary status, edition and coverage.

  3. 3

    Build the master taxonomy

    Extract the classification the sources actually use, rather than inventing one.

  4. 4

    Cross-reference

    Compare at least two independent sources wherever possible.

  5. 5

    Record conflicts

    Where authorities disagree, both readings are published with attribution.

  6. 6

    Publish

    A record is created only after the underlying type is verified. Unverified material stays out of the catalogue.

What is never invented

  • Catalogue numbers, mint marks and serial formats
  • Dates, denominations, weights and dimensions
  • Manufacturers, rulers and issuing authorities
  • Rarity, prices and auction results
  • References and photographs

Where evidence is missing, the record says “research required” instead of guessing.

Identification is not valuation

Identification, condition, rarity and market value are four separate things. A rare object can be inexpensive; a common one can be valuable in exceptional condition. This catalogue answers what an object is — not what it is worth.

Images

Only photographs of real objects are used, from public-domain, museum or openly licensed sources, each credited with its licence and original page. Machine-generated images are never used to depict a real object.

Review and revision

Submissions from collectors enter a pending queue and are never published automatically. The workflow is: submitted → reviewed → sources checked → approved → published. Records keep their revision date, and changes of attribution are recorded with the source that justified them.
