Denver ? The U.S. Mint agreed Friday to pay $9 million to female workers at its Denver plant who alleged their bosses demanded sex in exchange for promotions, harassed them and retaliated when they complained.

The deal, which must be approved by an Equal Employment Opportunity Commission judge, also calls for the appointment of an independent monitor at the facility for three years, Mint spokeswoman Becky Bailey said.

As many as 130 women could share in the settlement if it is approved, said Lynn Feiger, who represented the workers who filed the complaint.

The complaint was filed in 2003 by 32 women who alleged that pornography was openly displayed at the Denver plant and women were subjected to unwanted sexual advances and sexual discrimination by male workers and managers.
