Hundreds of items owned by Boston gangster James "Whitey" Bulger are going on the auction block this weekend.

Interested buyers can bid on a sterling silver "psycho killer" skull ring, a rat-shaped pencil holder and a stack of books about the mafia. Many of the items were taken from the apartment in Santa Monica, California, where Bulger and his longtime girlfriend were captured in 2011 after 16 years on the run.

Proceeds from the auction will be distributed among the families of Bulger's victims, including 20 murder victims and several extortion victims.

The live auction will be held Saturday at the Boston Convention and Exhibition Center along with a simultaneous online auction.

The 86-year-old Bulger is serving a life sentence in federal prison.
