More than 50 items of jewellery including rings, watches and necklaces have been recovered by police, who hope to reunite them with their owners.
They were found by officers during the arrest of five people on suspicion of burglary in Billingshurst in January.
Detectives believe they may have been stolen in burglaries in Sussex but have been unable to link them to any crimes.
Photographs have now been uploaded here in the hope their owners can identify them.
Investigator Rebecca Doherty said: “We are sure that these items have been stolen but we need to know where they have been stolen from so they can be given back to their rightful owners.
“If we can prove they have been stolen, it would also help us to prosecute those who we believe took them.
“If any of the items are yours, or if you recognise any of them, please contact us.”
