PROVIDENCE, R.I. -- Former Boston Red Sox pitcher Curt Schilling -- whose video game company underwent a spectacular collapse into bankruptcy last year -- is selling the blood-stained sock he wore during the 2004 World Series.

Chris Ivy, director of sports for Texas-based Heritage Auctions, says online bidding begins around Feb. 4. Live bidding will take place Feb. 23.

The sock previously had been on loan to the National Baseball Hall of Fame and Museum. It has been at Heritage's Dallas headquarters for several weeks and will be displayed at the auction house's Manhattan office before it is sold, according to Ivy.

He said the sock is expected to fetch at least $100,000, though he described that as a conservative estimate.

"I do expect the bidding to be very spirited," Ivy said.

Schilling's company, 38 Studios, was lured to Providence, R.I., from Massachusetts with a $75 million loan guarantee in 2010. In May, it laid off all its employees and it filed for bankruptcy in June. The state is now likely responsible for some $100 million related to the deal, including interest.

Schilling also had personally guaranteed loans to the company and listed the sock as bank collateral in a September filing with the Massachusetts secretary of state's office.

Messages left for his publicist were not immediately returned.

The bloody sock is one of two that sent Schilling into the annals of baseball lore in 2004.
