Human skull [file]

The seller asked 100 Euros (US$145) for the skull, which he said was found in a closet.

Many curious lookers were attracted to his stand, and some asked the price but none offered to buy.

"There are no real buyers, people only ask the price. I've been trying to sell it for ten days," said the vendor who refused to be identified.

The skull originally belonged to Belgrade's Institute of Forensic Medicine, he claimed.

A pathologist estimated it was approximately 50 years old and said there were signs showing it had been treated by pathologists.
