collector's item
An object of great interest, value, or rarity, as in This necklace is a collector's item. Originating in the early 1900s as collector's piece, a usage still common in Britain, the term in its present form is occasionally transferred to persons as well, as in The Beach Boys became a collector's item on the tour.
