Heritage Auctions framed the sale as a celebration of Monroe's legacy on her centennial, with Joe Maddalena praising collectors for responding "with extraordinary enthusiasm to objects that reveal the woman behind the legend."
The depth of private correspondence sold — including Dr. Greenson's letter written just 11 days after Monroe's death recounting the events of her final day — is generating buzz among collectors and historians who see this as a raw, unguarded look at her unraveling.
The auction took place June 1, 2026 — what would have been Monroe's 100th birthday. Total take: £1.86 million (~$2.5M). The top seller was the Christian Dior suit from her 1954 honeymoon with Joe DiMaggio, which set a record at £334,665 (~$449,493.58) for a non-performance-worn Monroe garment.
$2.5 million is a lot of money for fabric and paper — but what collectors are really paying for is access to the parts of Marilyn Monroe that Hollywood tried so hard to bury.
The estate sale that Marilyn Monroe never asked for just became one of the most significant celebrity auctions in recent memory. On June 1 — marking what would have been the blonde icon's 100th birthday — Heritage Auctions moved £1.86 million (roughly $2.5 million) worth of her personal belongings, drawn from the collection of Norman and Hedda Rosten, close friends who knew Monroe far beyond the studio lighting and press junkets.
The headliner: a Christian Dior suit that Monroe wore during her 1954 honeymoon with baseball legend Joe DiMaggio after their famously brief 275-day marriage. The powder-pink ensemble fetched £334,665 — approximately $449,493.58 — making it the highest price ever recorded for a non-performance-worn garment associated with the actress. For context, that's roughly half the value of some Hollywood homes in this economy, all for clothes she wore on vacation.
But if you think the Dior suit was the real story, you haven't heard about the letters. An eight-page handwritten letter from playwright Arthur Miller to Monroe — written as their marriage crumbled and penned with the kind of raw vulnerability that doesn't survive contact with a PR team — sold for £46,481 (~$62,452.57). These were not love notes.
Sources familiar with the correspondence describe it as Miller's desperate attempt to salvage something both knew was already gone. Even more chilling: three letters from Dr. Ralph Greenson, Monroe's psychiatrist, also went under the hammer for £46,481.
One of those letters was written just 11 days after Monroe's death on August 5, 1962 — a haunting first-person account of her final day and its immediate aftermath that reads less like clinical documentation and more like grief made ink. For collectors, this isn't memorabilia. It's a autopsy.
Also sold: triple-hoop pendant earrings worn when Monroe arrived at New York's Idlewild Airport in September 1954 to begin filming "The Seven Year Itch" (£288,009 / ~$386,816), a Fabergé clock (£74,370 / ~$99,932), a rhinestone bracelet (£83,666 / ~$112,419) and Monroe's personal telephone book (£55,778 / ~$74,950). Joe Maddalena, Executive Vice President of Dallas-based Heritage Auctions, called the timing "especially meaningful," noting that "one hundred years after Marilyn Monroe's birth, collectors responded with extraordinary enthusiasm to objects that reveal the woman behind the legend." Whether that's tribute or trespassing depends entirely on how you feel about selling a dead woman's psychiatric records for five figures.
