Martin Luther King Jr.'s heirs have ended a years-long legal battle over ownership of the civil rights leader's 1964 Nobel Peace Prize Medal.

A trial to determine whether the medal would be sold was scheduled to begin in Atlanta on Monday. But Reuters reported that instead, a court document requesting the suit be dismissed was filed. It did not indicate if the item would be sold.

The judge signed an order in which the parties asked to end their legal dispute, and agreed that the keys to a court-controlled box holding the medal until the resolution of the case should be given to Martin Luther King III.

Three of King's children serve as directors of an organization designed to manage their father's estate. Martin Luther King Jr. was assassinated in 1968, and died without a will.

Martin Luther King III and Dexter King voted in favor of selling the medal January 2014, but Bernice King objected to the sale of this and other "sacred" family heirlooms.
