Police hope a potential buyer may recognise the stamps when offered the stolen haul. The collection contains stamps mainly from Britain’s Atlantic outposts Ascension Island, St Helena where Napoleon was exiled and Tristan de Cunha.
It is not known whether the collection was the target of the robber, who also took the 72-year-old’s phone, debit card and umbrella.
The man was walking through an alleyway in Enfield at around 10pm when a hooded man walked past him before turning around and coming back to mug him.
Detective Constable William Darko investigating said: “This was a cowardly offence committed against a vulnerable elderly gentleman who has been deeply affected by the incident.
“Sadly, we are well aware that the effects of becoming a victim of robbery can run far deeper than a loss of property.
A Met Police spokesperson added: “Police are appealing for information after an elderly man was robbed of a valuable stamp collection.
“At 22.20pm on Thursday, December 10, 2020, the victim, a vulnerable 72-year-old man, was walking through the alleyway from Canning Square to Magpie Close in Enfield.
“The suspect, an olive-skinned male wearing a hooded top, walked past the victim, but then turned and grabbed him from behind taking his possessions.
“The suspect went through the victim’s pockets and stole his wallet which contained his Freedom Pass and debit card, his mobile phone, an umbrella and a catalogue of collectable stamps worth around £5000.”
