Nate D. Sanders Auctions

A trove of items once owned or gifted by Monica Lewinsky, including a black negligee and a letter signed by President Bill Clinton, is being auctioned online, Nate D. Sanders Auctions announced Monday.

The 32-item collection was submitted by Lewinsky’s one-time lover Andy Bleiler to special prosecutor Kenneth Starr during his investigation of the former White House intern’s sexual relationship with Clinton, said Laura Yntema, the auction manager.

Details of Lewinsky’s sexual relationship with Bleiler surfaced amid the probe that led to Clinton’s 1998 impeachment by the House of Representatives on perjury and obstruction of justice charges.

Clinton was later acquitted by the U.S. Senate.

Bleiler, Lewinsky's former high school teacher, was married at the time of his five-year affair with the San Francisco native, Yntema said.

It is believed Lewinsky was friendly with the Bleiler family in the 1990s, Yntema added.

The collection includes:

a "sheer black floor-length negligee by City Culture,"

"three sealed and slightly crushed boxes of presidential M&Ms,"

handwritten notes and greeting cards signed by Lewinsky,

a letter typed on White House stationary signed by Clinton,

... and several articles of casual clothing Lewinsky gave to Bleiler’s wife, Kate Nason, according to the lot description.

Lewinsky's infamous "blue dress" is not among the items listed for sale.

The lot is expected to nab between $25,000 and $50,000 when bidding concludes Thursday, Yntema said.

Yntema said she was not sure why the items were used as evidence during Starr’s investigation into Clinton’s misconduct.

Lewinsky, 39, has largely avoided the media limelight after dominating tabloid headlines and late-night talk show jokes throughout the late 1990s.
