Police have released images of about 200 pieces of jewellery and other valuables in a bid to trace their owners.
Officers seized the property, including rings, watches, pendants, bracelets and trophies, at an address in Cambridge, but detectives believe the items may have been stolen from homes across Cambridgeshire, Hertfordshire, Bedfordshire and neighbouring counties including Norfolk and Suffolk.
Each of the items has been posted on the force's Facebook page and burglary victims can email officers to claim them.
The valuables will also go on display during an open day at Parkside police station in Cambridge next Saturday.
Det Sgt Chris Tatum-Horsfield said: 'If you have had valuables stolen during a burglary in the 12 months leading up to April this year, I would urge you to come along to the open day.
'Officers will be on hand to show the seized items and hopefully reunite victims with their property.'
If you recognise any of the items or need more information, email OpRobbin@cambs.pnn.police.uk or call 101.
