The Saleroom, a British auction house, has 18 human skulls from Ancient Egypt up for sale, according to the auction website.
The skulls of ten men, five women and three people of undetermined sex are for sale with a guide price of £200-£300, or about $250-$380.
Several skulls are more than 3,000 years old and date from 1550-1292 BC, brought from Thebes.
Such a sale has drawn criticism from some experts, who have called for a review of laws governing the sale of human remains.
For example, Dan Hicks, a British museum specialist, told the US media that "it's quite a shocker" to see the skulls for sale.
"Every generation or so, surely we need to check in on our ethical compass on these questions and just ask, is this really right?" he said.
Laura Van Broekhoven, the director of the Pitt Rivers Museum, reportedly said that she was "really surprised that auction houses are still doing this."
"I would hope that we would stop selling and commodifying human remains of communities that really have tried to have dignified ways of, and usually ritual ways, of dealing with their ancestors," she said.
In early April, the British Museum was in the spotlight as an investigation was launched against it by the Information Commissioner's Office (UK's information watchdog) over allegations of excessive secrecy regarding a collection of sacred Ethiopian altar tablets that had been hidden from public access at the museum for more than 150 years.
The 11 wooden and stone tablets, which were stolen by British soldiers after the Battle of Maqdala in 1868, have never been on public display and are considered highly sacred.
