Federal prosecutors want to seize about $10,000 from the prison account of 98-year-old ex-mobster they say boasted about killing 60 people in his life.

John “Sonny” Franzese’s son Michael tells the Daily News his father needs the money to buy eye drops, soup and sometimes ice cream. He says family members have put up the cash.

Sonny Franzese was convicted of extorting a strip club while he was underboss of the Colombo crime family. He’s at a Federal Medical Center in Massachusetts.

Franzese once lived the high life — hanging out with Frank Sinatra and Sammy Davis Jr. at New York’s Copacabana nightclub. He also had a stake in the porn film “Deep Throat.”

Prosecutors contend the seizure would still leave Franzese $250 in spending money.
