Several of billionaire Bernard Madoff's possessions were sold in a New York City auction over the weekend, as part of the disgraced financier's assets' liquidation, included in his plea bargain.

Madoff, who is the admitted mastermind of what has been described as the largest Ponzi scheme in American history, was sentences to 150 years in prison for his crimes.

According to M&C News, among the pieces sold in the recent auction, were one of his wife's diamond ring and a Steinway grand piano.

The 10.5-carat diamond ring sold for $550,000, while the Steinway grand piano sold for $42,000.

The proceeds from Saturday's auction are meant to be used to repay Madoff's victims.
