FACTORS WE CONSIDER

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

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 historyAuction 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.
