Police are appealing for help to trace the owners, or buyers, of suspected stolen commemorative coins which have been recovered from a house in Hartlepool following a search.
Officers discovered several coins and documentation to suggest that other coins had been sold at auction on August 19.
Many of the coins are in presentation boxes and police believed that they may have been catalogued by the owner as they have small white stickers on them with what is believed to be Arabic writing.
