Heritage Auctions will sell more than 80 previously unseen personal items belonging to Marilyn Monroe on June 1, 2026 [1].

The sale coincides with the 100th anniversary of Monroe's birth [1]. Because these items have remained hidden from the public, the auction offers a rare glimpse into the private life and mental state of one of the most photographed women in history.

The collection includes a diverse array of artifacts, ranging from high fashion to intimate records. Among the highlighted lots is a Christian Dior suit and various pieces of jewelry [1, 2]. The auction also features more personal documents, such as private letters, drawings, and psychiatric notes [1, 2].

These items provide a contrast between Monroe's public image as a Hollywood icon and her internal struggles. The inclusion of psychiatric notes suggests a level of intimacy rarely seen in public sales of celebrity memorabilia. By releasing these documents, the auction aims to commemorate the actress's centennial while providing collectors with unique historical materials [1, 2].

Heritage Auctions has not released specific price estimates for the individual lots, but the rarity of the "unseen" nature of the items is expected to drive significant interest. The June 1 date marks a global milestone for Monroe's legacy, as the world recognizes the century since her birth [1].

The sale of psychiatric notes and private letters represents a shift in celebrity archiving, where the boundary between public persona and private medical or emotional history is further eroded for the sake of historical preservation and commercial value.
