Marilyn Monroe’s Baby Grand Piano: $662,500

It belonged to an icon and it was bought by an icon. Marilyn Monroe had tracked down the piano, which belonged to her mother Gladys Pearl Baker and was sold many years before the latter’s demise. Marilyn simply loved the white lacquered baby grand piano. She even mentioned it in her autobiography. It was auctioned for sale in a Christie’s auction in 1999 along with other Monroe memorabilia. The highest bid was by pop star Mariah Carey who paid $662,500 for it.
