British and US money, a two-carat diamond ring and a horse whip-shaped gold tie pin have been stolen from a house in County Durham.
The burglary happened at some time between 1730 GMT and 2000 GMT on Wednesday at Park Avenue, Coundon Gate.
Thieves are believed to have climbed the backyard wall and kicked in the back door to get inside the house.
Police said the cash amount stolen was "substantial" and the items stolen "sentimental".
Officers said the US Dollars were all new notes. Also stolen were personal papers and bank cards.
The gold tie pin is described as being in the shape of a horse whip with a small horse shoe in the centre bearing the inscription, "Horse Artillery 19th field".
Police said they wanted to speak to any witnesses or anyone with information about the items stolen.
