rarity

RAIR-uh-tee/ˈrerəti/

The condition of being uncommon.

The ancient coin's rarity sets it apart from the collector's common specimens.

A collector carefully displays one unusual ancient coin apart from common coins, singular rare object.
Etymology

The original image is of things thinly spread, with spaces between them: sparse things are few, and therefore uncommon. Rarity shifted from the condition of being uncommon to an uncommon thing itself.

In context
