Thieves let themselves into a pensioner’s home in Horam and stole his wallet on Tuesday morning (July 30).
The pair called at the house of the 82-year-old at Horam Manor Bungalows at 10.30am.
The pensioner answered the door and the men held up a card which may have had a photo on it.
Sussex Police are appealing for witnesses and information.
Detective Constable Mark Davis, who is investigating the incident, said: “At this point one of the men went into the kitchen and the other into the living room.
“They left shortly afterwards, at which point the victim discovered his wallet containing some cash and cards had been stolen.”
Both men were described as white, about 6ft tall, in their 30s and clean shaven.
The first man, who had short dark brown hair, was of larger build than the second man, who had straight brown hair.
DC Davis added: “If you were in the area on Tuesday morning and saw these two men, or have received similar visits recently, please call us on 101 quoting serial 0483 of 30/7.
“You can also call the independent charity Crimestoppers anonymously on 0800 555 111.”
