FACTORS WE CONSIDER

Age & historical period

Older items from significant historical periods generally command higher rarity scores. A Georgian piece scores higher than a Victorian equivalent.

Evaluate period alignment with AI analysis

Condition & preservation

Exceptional preservation significantly increases rarity. An intact specimen is far rarer than damaged examples of the same item.

Provenance & documentation

Items with documented history, especially from named collections or famous owners, receive elevated scores.

Analyze provenance gaps in ownership history

Auction frequency

We analyze how often similar items appear at major auction houses. Less frequent appearances indicate higher rarity.

Cultural & scientific significance

Items of particular importance to history, science, or culture receive additional rarity consideration.

Craftsmanship & uniqueness

Exceptional quality of execution or unique characteristics within a category boost the rarity score.

Important Note

Rarity scores are generated by AI analysis and are intended for entertainment and general guidance only. They should not be considered professional appraisals. For significant purchases or sales, always consult with qualified experts and auction houses. Rarity also affects insurance documentation. Market conditions and new discoveries can rapidly change an item's rarity status.
