Detectives investigating the murder of a 76-year-old man in Cambridgeshire have released a picture of a rare coin thought to be missing from his house.
Llywelyn Thomas was found dead in the bedroom of his home in Chittering on 18 December, following a botched burglary.
The 1668 Robert Brooke halfpenny was one of 50 to 100 coins in a burgundy folder believed to have been stolen along with three watches and a wallet.
Officers are also looking for a poker which may have been the murder weapon.
Det Ch Insp George Barr, from Cambridgeshire Police, said: "These are very distinctive coins and I would urge any collectors who have been offered them to call police."
