Jewellery and watches were among items stolen during a burglary at a home in Hemel Hempstead.
The items were taken from a property in Peascroft Road between 7pm on Saturday, February 3 and 2.30am on Sunday, February 4, when entry was gained after glass in a rear patio door was smashed.
"Our enquiries are continuing at this time, including a review of any CCTV or doorbell camera opportunities," said Detective Constable Gemma Ball, from the Dacorum Local Crime Unit.
"As part of the investigation, we’re releasing these images in the hopes that someone might have come across them since the weekend.
"Have you seen them discarded or advertised for sale anywhere? Did you witness any suspicious activity in the area between the times stated?
"If you have any information at all that might assist us, please get in touch."
