one-of-a-kind items

Irreplaceable individual objects

Objects that are unique—either literally singular or so rare and distinctive that no equivalent exists.

The phrase emphasizes irreplaceability: The estate sale featured one-of-a-kind items from the artist's personal collection.

Often used in retail and collecting to suggest special value, though the term gets stretched to cover anything marketed as distinctive.
