Among other things, the authorities in New York intend to return five works from the Metropolitan Museum of Art (The Met).
At the same time, 58 works of art are being returned to Italy, including a bust of the goddess Athena dating to 200 BC.
"Today's repatriation demonstrates the breadth and scope of the antiquities trafficking networks," Manhattan District Attorney Alvin Bragg said in a statement.
Worth more than SEK 170 million
According to Bragg, the 16 works of art to be returned to Egypt are worth more than SEK 170 million.
Nine of the works were owned by collector Michael Steinhardt.
In 2021, authorities forced him to return 180 ancient objects believed to be stolen.
He avoided prison but was banned from dealing any more in antique art.
Five additional works of art were seized this spring from The Met by French and American authorities, and former Louvre director Jean-Luc Martinez was charged.
The objects came from the looting of archaeological sites in Egypt, which were then smuggled through Germany and the Netherlands to France and from there resold to The Met.
The investigation has led to the prosecution or arrest of nine people in France.
The police's anti-trafficking department has said more works will be seized and returned to their countries of origin.
