The items read like a treasure trove of riches for New York royalty.

A 10-room apartment in a luxury cooperative one block from Central Park. A vintage convertible once owned by Lauren Bacall. Joe DiMaggio’s No. 5 Yankees jersey, signed and framed.

On Tuesday, the owner of these valuables, Rudolph W. Giuliani, 80, must surrender them all, and more, to two election poll workers in Georgia, whom he defamed and who won a $148 million judgment in a lawsuit.

The order, by a Federal District Court judge last week, is an epilogue of sorts. Mr. Giuliani was once a widely beloved mayor who fashioned himself as the quintessential New Yorker. He was a leader respected far beyond the city before ultimately aligning himself with Donald J. Trump and promoting election conspiracy theories that cost him his reputation, his vocation and his broad appeal.

Mr. Giuliani now stands to lose something just as precious — his carefully curated New York identity, built over decades in the spotlight, one trophy at a time. For a Brooklyn-born power broker, whose legal troubles have stripped him of his last home in the city, it approaches exile.

Mr. Giuliani has cited the court order in a fund-raising email for his legal defense.

“They want my home, my belongings, even all of the nostalgic keepsakes that I’ve collected throughout my 80 years of life,” he wrote in the letter, before adding he will “NEVER SURRENDER the fight.”
