More than 100 items looted from Iraqi museums have been handed in to US-led coalition forces, according to the American military.
Looters cleaned out much of the national museum
They are said to include priceless manuscripts, a 7,000-year-old vase and one of the oldest bronze bas-relief representations of a bull.
The United States pledged to recover and repair priceless antiquities looted from Iraq's national museum in Baghdad and other institutions in the wake of the rout of Saddam Hussein's forces, and has offered rewards for their return.
Coalition forces were criticised for not protecting the national museum, which housed many treasures from "the cradle of civilisation".
In a statement, US Central Command in the Gulf state of Qatar said: "Iraqis started to return the items after coalition forces began urging local residents to return any artefacts taken during the looting in Baghdad.
"One man returned a chest filled with priceless manuscripts and parchments to a nearby mosque, a local pianist returned 10 pieces including a broken statue of an Assyrian king dated to the 9th Century BC and one of the oldest recorded bronze bas-relief bulls.
"And after some negotiation, a man arrived with 46 stolen antiquities, then with eight more pieces, and finally with a 7,000-year-old vase.
"Every day, Iraqis approach coalition forces with information about missing antiquities, and coalition forces follow up and investigate those tips. Coalition forces will continue to work with the Iraqi people to recover priceless antiquities."
